Termination Systems for Polymeric Insulated Cables up to 72 kV

Application

Raychems terminations up to 72 kV are suitable for all climates and environments, even severely polluted areas, and for all installation condi-tions, including top feed installation. The factory-engineered kits contain a proven termination system which saves space, facilitates installation and enhances system reliability. The spe-cial design of the termination, which incorporates pre-coated tracking resistant sealants that melt during the shrinking process, results in a reliable and lasting barrier against moisture and corrosion.

Features

The slim, compound-free Raychem Terminations are suitable for indoor and outdoor use on all polymeric cables for voltages from 42 kV up to 72 kV.

Major Design Elements

Kit content:The kit contains a limited number of light-weight components with unlimited shelf life under normal stor-age conditions. The heat-shrinkable sleeves are extremely versatile, and accommodate a wide range of cable diameters. Four basic kits cover all cable sizes, permitting reduced inven-tories and ef cient stocking policy.The lightweight of the components and limited volume of the kits facili-tate safe and easy transportation and handling. All components are included in a single box. The set of pre-engineered compo-nents requires no special or expensive tools for installation. Installation involves a simple set of standard procedures with no soldering re-quired. Neither does the termination require lling with oil or compound. Risk of leakage is avoided, and lling and topping-up time on the job site is saved.

High Performance Material:Raychem terminations are made of a specially formulated material with excellent tracking and erosion resist-ance characteristics. Accelerated and natural weathering tests which have been carried out at Raychem facilities and independent test sites around the world have demonstrated that the terminations are UV and water resistant and perform reliably even when exposed to sudden temperature variations. A Tracking and Erosion Test as per ASTM D2303 showed no tracking. IEC 112 was also conducted with no erosion or tracking observed.

Electrical Stress Control:Screened or shielded power cables require electrical stress control in order to reduce the electrical stresses at the end of the screen and at the termination surface to avoid partial discharge and surface corona under all service conditions. Corona or electrical discharge can ultimately destroy the cable insulation, causing premature failure.Raychems stress control sleeves have electrical properties that smooth out the electrical eld at the end of the cable. This is achieved by the unique resistive and capacitive properties of the heat-shrinkable materials.

A Universal System:The material used in these termina-tions is suitable for all climates and environments. It is not susceptible to damage from transportation or vandalism. The termination has a discreet, low pro le which allows it to blend into landscapes.

Dry Self-Supporting Outdoor Termination OHVT up to 145 kV

Application

The dry self-supporting termination is designed for voltage classes up to 145 kV and operation under severe environmental conditions. It is free from any insulating liquid or gel. Polymeric insulated cables of various designs can be adopted with respect to shielding and metal sheath. The polymeric housing with long creepage length covers extreme pollution levels according to IEC 60071-1 1996, IEC 60071-2 1996 and IEEE-1313.1-1996. Its mechanical performance is similar to conventional oil- lled terminations with composite housing.

The termination is easily separable and consists of a plug-in part and an epoxy resin insulator protected with directly moulded silicone shed hous-ing. Due to the short cable cutback dimensions of the plug-in the time required to install the termination is very short and can be further reduced in case of short cable links by pre-in-stalling the plug-in on the shop oor.

The plug-in is similar to the plug-in used with Tycos dry switchgear/ transformer termination.

Dry Compact Switchgear & Transformer Termination PHVS & PHVTfrom 72 kV up to 145 kV

Application

The dry compact switchgear termina-tion for voltage classes up to 145 kV is designed to be installed in cable entry housings of gas-insulated switchgear (GIS). It complies with IEC 62271-209 standard, which essentially speci es the interfaces between the termina-tion and the switchgear.Therefore the termination will t into all GIS complying with IEC 62271-209.An adapter is available to match the dimensions of wet (oil- lled) type terminations, which are also speci ed in IEC 62271-209.

The termination operates in SF6 but also in insulating liquids like trans-former oil. A corona shield at the top of the termination then provides the necessary shielding of the terminal.The termination is easily separable and consists of a plug-in part and an epoxy resin insulator. The insulatorcan be installed by the GIS or trans-former manufacturer already at the factory saving installation time onsite and reducing the risk of contamina-tion of the cable entry housing. In case of short cable links and due to the short length and light weight of the plug-in part it can be also pre-installed by the cable manufacturer further reducing the time required to install a substation.

The exible double sealing system is installer-friendly and ensures persistent leak tightness of the top assembly. Heat shrinkable polymeric tubing contain-ing oil-resistant sealant encapsulates the connector barrel and the poly-meric insulation transition.


The interface between stress cone, cable insulation and inner GFR housing is lled with silicone oil (4) through a lling nozzle at the base plate.

The cable outer serving is adapted through a gland system (8), whichaddresses the individual shielding and armouring of the cable. Heat shrink-able tubing is used to seal the cable gland.

Joints for Polymeric Insulated Cables EHVS from 42 kV up to 72 kV

27


Designed for easy jointing:The Raychem joint design comprises of a connector that allows even large cross-sections to be jointed and two dual-wall, heat-shrinkable sleeves. A heavy-walled co-extrusion of two layers of red insulation forms the inner sleeve. The outer sleeve consists of a thick layer of red insulation co-extrud-ed under a black outer conductive layer which acts as the joint screen.

Kit Content:The set of pre-engineered compo-nents and the Raychem connector require no special installation tools. After placing the heat-shrinkable components over the cable end, the connector is installed by tightening the special bolts, which shear off cleanly when the correct contact force is reached. Each sleeve in turn is placed over the connector area and shrunk down. Copper shielding mesh and an adhesive-coated outer sleeve for water sealing then complete the joint.

Controlled-torque Connector:The connector design allows cables to be jointed without special tools, heat treatment as dressing/ ling after installation. Shear-head bolts ensure a pre-engineered electrical connection. The shear-head bolts break off at a pre-determined level below the outer surface of the connector, at a de ned torque. This ensures the correct con-tact pressure is reached every time. The stable voltage drop provided by this concept has been demonstrated in eld installations which closely follow the predictions of long-term load-cycling tests.Comprehensive quali cation proce-dures like IEC 61238-1996 and ANSI 119.4 1993 prove the excellent long-term performance.

28

Electrical Stress Control:A material with stress adjusting characteristics is applied onto the connector and cable screen ends. This heat-shrinkable sleeve incorporates a conductive coating in the connector area which equalizes potential in the manner of a Faraday cage. It extends over the dielectric to accommodate possible insulation shrink-back.

Cross-bonding / shield break:The use of heat-shrinkable sleeves for stress control, insulation, and screen-ing provides a location for the shield break at the end of the joint.

Outer Sealing:The cable oversheath is replaced with a thick-wall heat-shrinkable insulating sleeve, which provides the required dielectric strength and create an effective water seal and corrosion protection.

Elastomeric Technology:Two dual-wall, heatshrinkable elas-tomeric sleeves shrink rapidly and deliver pre-engineered, uniform layers of thick insulation. The outer layer shrink to the pre-determined diam-eter and the elastomeric inner part con rms tightly to the joint.

The joint consists of connector (1), cable adapters (2) including stress cones and main joint body (3) con-taining Faraday cage (7) and outer serving by heat-shrink technology (9,12). The conductors of the cable are connected by a mechanical connec-tor sleeve (1) using torque controlled shear-off bolts. The connector sleeve is suitable for stranded aluminium and copper conductors but can be easily modi ed to accept solid conductors as well. The Si-rubber cable adapters (2), accommodating the various cable insulation diameters, build up the connection area to an almost constant diameter. This allows to cover dif-ferent cable cross-sections with just one main insulation joint body (3). Therefore cross-section transitions are possible without any extra compo-nents.

No extra tooling is needed to push-on the Si-rubber cable adapters (2) and the Si-rubber joint main body (3) due to its excellent elasticity.

A metal shielding clamp (7) on top of the connector ensures perfect heat transmission and a smooth interface t. The xing rings (6) keep the cable adapter and the cable dielectric in position.

During the installation the main body is parked on the over sheath of the cable. This keeps the cut back length and cable preparation time as short as possible. Mechanical solderless con-nector technologies (8) are used to connect metal shields copper wires, metal sheath and CAS. Heat-shrink technologies (9,12) replace the cable serving and the moisture barrier. The joint concept is similar for the shield break joints, despite the shield continuity.Special sealant components make it possible to use double-insulatedground leads, and thereby to utilise the proven heat-shrink technology.

Application:

Add-on kits for HV cables with integrated glass bres are available for all Raychem 145 kV terminations and joints. The add-on kits include all required components to reliably seal the cable and the glass bre outlet as well as suitable tubes to protect the sensitive steel pipes carrying the glass bres. The standard kit can be used for cables with up to two individual steel pipes. Glass bre splicing kits may be included in the add-on kits as well. These kits are able to handle up to 12 individual glass bres per steel pipe. The commonly used FOSC 500 splicing kit is able to take two steel pipes so up to 24 glass bres can be spliced with this splice box. The box is isolated and is therefore suitable for cross bonding joints as well.

The glass bre outlet is arranged straight, which means the pipe doesnt need to be fold back. This saves the pipe from being snapped off because its smallest permitted bending radius usually is bigger than the diameter of the power cable.

cable manufacturers

We are able to offer following services: Installations (accessories only) Trainings (on-site and in-house) Supervisions

InstallationsTyco Electronics has got well trained and experienced jointers which are able to carry out installation at construction sites. Usually they are supported by local helpers provided by the contractor or the local utility.In case there are no trained jointers available locally ordering installation services from us is the rst choice.

TrainingJointers with 5 years or more experi-ence in HV cable preparation may be trained on-site during an installation. Less experience jointers should be rst trained in our labs. In both cases well experienced supervisors demon-strate how to install our products in order to ensure the high performance expected to be enjoyed over the whole life time of our products.At the end of the training the jointers will be able to carry out installations without or at least with a minimum of help provided by our supervisors.

SupervisionJointers, which have been trained by Tyco Electronics supervisors prior to an installation but havent yet got suf- cient on-site experience in installing Tyco Electronics accessories, may need the help of a supervisor on-site. We recommend ordering this service for the rst installations. If ensures that all accessories are installed ac-cording to the instructions provided with the accessories.

For the installation of the cable accessories the construction side must be prepared before. The installation requirements for the different products are described on the following pages.

Introduction

Tyco Electronics Bowthorpe has been manufacturing surge arresters for over 60 years. Our knowledge and experience we use to develop our surge arrester range today.

Tyco Electronics is well known for their insulation and protection products worldwide. The range of HV surge arresters up to 550 kV and line discharge classes from 2 up to 5 operates in 130 countries in diverse climates from the artic circle to the tropics.

Since 1988 Tyco Electronics have designed the patented series parallel metal oxide surge arrester which is special in construction and provides many advantages over conventional single column and multiple columns porcelain and polymeric housed arresters. They were designed and tested to meet de ned abnormal service conditions as detailed in Annex A of IEC 60099-4 (1991).

The special construction of this series parallel surge arrester provides electrical and mechanical properties that cannot be obtained with single or multiple column types. In particular the geometry and unitary construc-tion provides inherent voltage grading that does not require additional grading rings or further correction of the maximum continous operating voltage (Uc) required for arresters of conventional construction.

For voltages up to 220 kV Tyco Elec-tronics offers two types of Polymeric Single Column Surge Arrester which also have their bene ts based on the construction and design.

Application

This range of Silicone Rubber housed surge arresters is applicable for sub-station equipment and transmission lines. Because of their high cantilever strength, they can be used to replace the cable support insulators on HV terminations. This results in simpli- ed installation for HV terminations at reduced cost which is aestheti-cally more acceptabIe to the general pubIic.

Bene ts

Low residual voltages High protection margins High TOV performance Inbuilt stress grading along the full length More effective grading per unit length than a single column type Similar stress distribution like single column type, but without stress grading

ring Resistant against Radial stress based on the gap free Bowthorpe patented

construction Safe non-shattering short circuit behavior to higher current levels High-energy handling Direct molded housing to prevent moisture ingress Hydrophobic and tracking and erosion resistant silicone housing High pollution performance Excellent cantilever and tensile performance Excellent mechanical, vibration and impact withstand capability Extremely strong mechanical strength Low thermal ageing of varistor insulation Smaller footprint than equivalent single column SA with grading ring Modular design for quick installation and commission Light weight Capable to withstand seismic condition Uniform current sharing Maintenance free Tested in accordance with IEC60099-4 at independent accredited

laboratories Quality design and manufacturing, ISO 9001 and 14001 compliant

52

Design Concept

Many 1-column porcelain housed and non-integrated polymeric housed type surge arresters have some limits. A few of them are the control of uniform stress grading and the radial eld strength which are the most important issues in these surge arrester design types. The high radial eld would lead to discharge in the surge arrester enclosure between the porcelain inside and the metal oxide varistors.

I. Single Modules for Single Column and Series Parallel Surge Arrester

A. Construction

The Tyco Electronics Bowthorpe patented surge arrester construc-tion eliminates the air gap by direct moulding of the silicone rubber hous-ing onto the wrapped ZnO varistor elements and the terminal assembly. The applied ZnO varistors ensure a very good electrical behaviour. The polymeric housing and the shed form ( gure 1a) shows a good performance in salt-fog tests.

B. Housing material

Housing material is a service proven formulation of Silicone Rubber. The silicone housing was developed using the knowledge accumulated over 35 years of internal Tyco Electron-ics materials science expertise and experience, resulting in an optimum shed pro le and a material with excel-lent tracking and erosion resistance. This range of Silicone Rubber housed surge arresters has been fully tested to meet the very severe pressure- relief tests.

C. Application

The advantages of the construction and the housing material are used for the Tyco Electronics Polymeric Surge Arrester independant if they are build in a single column design or in the series parallel design.

II. The Single Column Design

Tyco Electronics offers two types of single column Surge Arrester.

The construction of the arrester type HSR is manufactured with the above described modules. These arresters are available for voltages up to 132 kV as a class 2 Surge Arrester.

The type named PCA is designed as a class 3 Surge Arrester for voltages from 30 kV up to 220 kV.

III. The Module Series Parallel Design

Especially for higher voltages are some features like voltage distribu-tion, stress grading, thermal ageing, partial discharge and the weight important for the design of the Surge Arrester. Tyco Electronics developed the Module Series Parallel Design to build up the advantages for these higher voltages.

A. Voltage distribution and stress grading

The voltage distribution is largely governed by the surge arrester geometry and intermediate plates. The intermediate connection plates of the series parallel surge arresters provide additional natural grad-ing capacitance. The intermediate connection plates have stray capaci-tances which cascade and shunt to earth. Furthermore, the resistance and capacitance of the non-linear varistors also provide voltage grading.The equivalent cascade capacitance network (Fig. 1c) gives more uniform electric eld distribution when com-pared it with standard single column porcelain or non-porcelain house surge arrester with or without grading ring. Intermediate connecting plates assist the reduction in radial stress at extremely high voltage sections.The overall geometry of the modular surge arrester is such that both radial and longitudinal voltage stress was at an acceptable value at an extremely high system operating voltage.

B. Thermal ageing and partial discharge

An exponential longitudinal voltage grading of a surge arrester is undesir-able phenomenon for varistor disks especially for those which are in top of the Surge Arrester. Low energy ionisation of the parallel air gap due to the high electrical stress would lead to ageing and failure of the varistor insulation. It has been established that partial discharge activity in close proximity to metal oxide varistors will lead to rapid ageing and premature failure. Therefore, the conventional single column arrester requires a grading ring for the additional reasons other than uneven eld or thermal considerations.

Equivalent circuit network (Fig. 2a) can only handle the varistor element in its linear model either before or after the threshold turn on point.

For the former, varistors have high resistance and its capacitance that dictates the surge arrester voltage grading. Beyond the turn on point the varistors have low resistance and this dominates the voltage grading. Further more for the former case, although the varistor or varistors are seeing high stress, the equivalent network as shown in gure 2a, has high source impedance (Z). Under these conditions the voltage across the varistor will collapse as soon as any signi cant current commences to ow.The high equivalent source imped-ance effectively limited the voltage and current that can be applied to the varistor elements located in top surge arrestor section high stress region. It is in this context that further consideration must be given to actual ageing mechanism.

Thermal ageing of the varistor would be caused by the lack of self limiting under the combination of high stress and low source impedance. The series parallel surge arrester design has eliminated both, thermal and partial discharge ageing to the metal oxide arrester.

The Series Parallel surge arrester has no internal air gaps and therefore requires no grading ring to avoid internal ionisation.Figure 2b shows the coaxial circuit approximation model and gure 2c shows typical results obtained and con rmed the near uniform longitu-dinal voltage stress distribution. The Series Parallel surge arrester does not require external means such as grading rings, to aid the voltage distribution.

C. Comparison between seriesparallel and single column design

There are differences and similarities between the eld plot to a standard single column porcelain house surge arrester and the Series Parallel design. They are summarized as follows: The Series Parallel arrester has more

effective grading per unit length than the single column type

Specially a Series Parallel 4P type exhibits similar stress distribution to the IEC example calculations, but without use the oversize diameter voltage grading rings

Radial stress is an issue for many por celain housed design due to the inbuilt air gap between the varistor and the housing inner wall but not for the gap free (integrated housing) Tyco Electronics patented construction

D. Series Parallel surge arrester electrical tests

The following standard IEC routine testing for every series parallel surge arrester units: Reference voltage measurement Partial discharge measurement Leakage current measurement Residual voltage measurement

In addition, a proprietary internal procedure was introduced to check the current sharing of parallel columns within a series parallel surge arrester. A proprietary process ensures that between parallel columns the lowest practical differences in characteristics can be employed in one complete se-ries parallel surge arrester. Therefore, residual voltages, energy absorption and heat dissipation are shared among the parallel units.

E. Installation and maintenance ad-vantages of the series parallel design
