OverviewTyco Electronics, through its brand name Dulmison, have been supplying Heliformed® fittings tomarkets throughout the world for over 45 years. Dulmison obtained a manufacturing licence in1957, and became the first and oldest manufacturer of Helical line fittings outside North America.
Over the last 45 years, a range of Heliformed® terminations, joints, and support and repair fittingshave been developed. The range of application of these fittings is unsurpassed, and provides themost complete range of electrical distribution fittings of this type.
The apparent simplicity of Heliformed® fittings, their ease of installation in the field and theirmechanical and electrical conductive efficiencies, belie the design back-up and manufacturingexpertise necessary for what are essentially precision products. Heliformed® fittings are tailormade to match wide ranging differences in conductor materials, diameter configurations andservice conditions that vary from coastal climates to hot arid plains.
DesignAll Heliformed® fittings are designed to be compliant for use with the following Standardsand or Recommendations;
AS1222.1SC/GZ Conductors (Galvanised Steel)AS1222.2SC/AC Conductors (Aluminium Clad Steel)AS1531 AAC & AAAC Conductors (Aluminium and Aluminium Alloy)AS1746 HDC Conductors (Hard Drawn Copper)AS3607 ACSR Conductors (Aluminium Clad Steel Reinforced)
Heliformed® fittings are compliant with requirements of AS1154 Part 3.
InstallationHeliformed® fittings may be installed either by hand or by live line methods, and are designed tofit on to the conductor for which they are designed, without any question of malfunction ormisapplication.
Colour CodingColour Coding is determined by the stranding of the conductor, on which the Heliformed® fitting isto be used as per AS1154 Part 3.

FundamentalsHeliformed® Deadends have two lengths, Overall Length and Applied Length, the latter being thelength from the cross over marks. (See fig 1). The cross over mark, (See fig 2) shows the startingpoint for application of the deadend. The colour code at this cross over point is as per thestranding of the conductor (See colour code page 5). An identification tag is always attached tothe loop area of the fitting, and displays the fitting Cat. No., Range of Applications and/orstranding details.

Alpha Numeric IdentificationHeliformed® line fittings are identified by an alpha numeric catalogue numbering systemderived as follows:
• Nature of fitting material
• Type of fitting
• Conductor diameter range, applicable to fitting (Aust./N.Z Standard Metric)
Although examination of the list of ‘prefixes’ and suffixes’ listed below shows the system to belargely mnemonic, and thereby helpful in equating catalogue numbers with fittings, there are trapsand, as always, “exceptions to the rule” (see below)
Standard Abbreviations
PREFIXES (Material type)A Aluminium L Aluminium Clad Steel C Copper S Galvanised Steel
SUFFIXES (Fitting type)AR Armour Rod GG Heligrip®
DC Deadend for Copper GL Guy LokDE Deadend LG Line GuardDT Distribution Tie LS Line Splice
Steel Deadends are catalogue SGG (steel guy grip) rather than SDE.
Note: A true suffix ‘D’ appearing at the end of a catalogue number indicates the fitting suits morethan one conductor e.g. suits 7/2.75 Copper plus 19/1.75 Copper.

Aluminium Based Deadends have been designed as a simple and cost effective method ofcarrying out terminations on overhead distribution networks incorporating AAC, AAAC and ACSRConductors. Their unique single piece design, provides uniform application pressure to theconductor, and eliminates cumbersome hardware and other components, which may be lost ordamaged during installation or in service.
An entire range of fittings, have been developed, to cover the smallest earth wires, right up to thelargest transmission conductors. Each fitting has a specific application range, as indicated in thefollowing tables.
Rated Holding Strengths
On AAC and AAAC conductors, both an ADE and LDE fitting will hold a minimum of 90% of theultimate tensile strength of the conductor as required by Australian Standard AS1154.1 - 2004.On ACSR conductors, an ADE or LDE fitting will hold 60-85% of the ultimate tensile strength ofthe conductor, on which it is used.

Copper Alloy Deadends have been designed as a simple and cost effective method of carryingout terminations on Hard Drawn Copper (HDC) and Copper Alloy conductors. Fittings for smallerranges are manufactured from Tin Bearing Copper Alloy wire, whilst larger fittings aremanufactured from a unique Cadmium ‘Free’ Copper Alloy wire.
The material used in all fittings is ideally suited to coastal and polluted conditions, andreplicates the strength and life of the conductor as closely as possible.
Rated Holding StrengthsOn HDC conductors, a CDE fitting will hold a minimum of 90% of the ultimate tensile strength ofthe conductor as required by Australian Standard AS1154.1 - 2004.

The DIS fitting has been designed for terminating insulated aerial service cables of either single,webbed, 2, 3 or 4 core twisted or concentric neutral screened construction. The DIS fitting isdesigned to terminate the service cable directly to the facia attachment on the house, without theneed for a separate insulator. There is no span limitation in normal urban usage of the DIS fitting.
DIS fittings are composed of two compoments, a galvanised, gritted and coated (black)Heliformed® fitting, and a non-conductive Neoprene Sheath. The neoprene sheath is wrappedaround the service cable prior to attachment of the Heliformed® fitting, to provide the doubleinsulating layer.
The DIS fitting provides excellent resistance to UV attack and corrosion, and has been designedto operate in harsh operating environments, where temperature extremes, and vibration difficultiesare known to occur.

Note: Number of conductors includes the neutral screen.
The NDE is a coated galvanised steel termination, suitable for application over Polyethylene orNeoprene insulated, aluminium or copper conductors. The coated subsets of each Deadend legexert a low radial pressure that does not damage the insulation on the conductor.
Because of the number of variables associated with the rating strength of this type of fitting(conductor size, number of cores, insulation thickness etc.), it is impractical to imply a rating as aproportion of the UTS of the conductor. In many applications the strength of the fitting will exceedthe UTS of the conductor.

SGG and LGG Heligrips®, are used for teminating guy wires, earthwires and stay conductors.Both SGG and LGG fittings are ideally suited to installations in the most difficult conditions, andwill never relinquish their gripping power.
SGG and LGG Heligrips® are manufactured from the same materials as the conductors that theyare applied to. This ensures that there is no chance of electrolytic or galvanic corrosion, as thefittings are completely compatible to the conductor to which they are applied.
SGG fittings are supplied as Right Hand Lay as the standard to match the applicable Right HandLay conductor. Left Hand Lay fittings are available to suit Left Hand Lay conductors. LGG fittingsare always supplied as Left Hand Lay to suit Left Hand Lay conductors.
Rated Holding StrengthsSGG & LGG Heligrips® will hold a minimum of 90% of the UTS of the conductor as required byAustralian Standard AS1154.1 - 2004.
**Note: SGG0825. SGG0975 & SGG1375 are suitable for use with a standard thimble or with GY3 &GY4 insulators.

ApplicationProtection of conductors against bending & compressive stresses. Protection against abrasion &arcing damage. Repair of conductors having no more than 20% of outer strands damaged or broken.
Guide to UsageAs the degree of protection in specific situations is affected by such factors as line design,temperature, tension, exposure to wind flow, vibration history, etc., the followingrecommendations are made:
(i) Armour Rods should be regarded as minimum protection for clamp style supports orsuspension arrangements.
(ii) They should be considered as mimimum protection on hand tied, pin type constructionof span lengths greater than 90M in urban areas, having no history of vibration.
(iii) Armour Rods are not designed to act as vibration dampers. Their role is to provideconductors with an extra degree of protection at support points. In areas where ahistory of vibration is known, or where vibration is suspected, the supplementary use ofType SVD Heliformed® Spiral Vibration or Dogbone® Dampers should be considered.
(iv) On pin type construction, the use of Helities® are recommended as being superior tousual armour-clamp arrangements.
(v) At suspension points Heliformed® type HSU Suspension Units are recommended assuperior to usual armour-clamp arrangements.
Restorative RepairArmour Rods may be used to restore full conductivity and strength to aluminium, ACSR andcopper conductors, where damage is outside of the support area and does not exceed 20% of theouter strand layer. Tyco Electronics should be consulted when damage is located at the point ofsupport. The conductor should be scratch brushed and greased prior to the application of ArmourRods used for repair.
TappingHeliformed® Armour Rods may be used as tap armour to protect conductors from wear and flash-over damage under hot line taps. Where tapping clamps are to be installed over the Armour Rodsa moisture inhibitor, e.g. Alminox, should be applied. The conductor should be scratch brushedand greased prior to the application of Armour Rods used for tapping.

Note: Helities® and Distribution Ties are available for installation over Armour Rods.Refer to table on Page 7-21.
ApplicationLine Guards may be regarded as a light duty version of the armour rod intended for protection ofconductors against abrasion and arc-over. They may also be used as patch rods to conductorswhere damage has occured.
CompatibilitySuited to highly polluted areas and coastal locations when used with appropriate conductor.
Guide to UsageAs with Armour Rods, the degree of protection afforded conductors against abrasion andarc-over is influenced by such factors as line design, temperature, tension, exposure to wind flowand vibration etc. The following may be taken as a guide:
(i) Regard as a minimum protection for hand tied spans of less than 107m in urban areaswith a history of vibration.
(ii) It is recommended that Helities® be used in place of normal hand tie combinations onpin type construction.
(iii) Line Guards are recommended where clamp type supports or suspensions are used orwhere there are hand tied spans of 91m or more. In these situations Heliformed®
Armour Rods are preferable.
(iv) Line Guards are not recommended where vibration is suspected.
Restorative RepairLine Guards may be used to restore full conductivity and strength to aluminium, ACSR andcopper conductors, where damage is outside of the support area and does not exceed10 - 15% of the outer strand layer. Tyco Electronics should be consulted when damage is locatedat the point of support. The conductor should be scratch brushed and greased priorto the application of Line Guards used for repair.
TappingHeliformed® Line Guards may be used as tap armour to protect conductors from wear and flash-over damage under hot line taps. Where tapping clamps are to be installed over the Line Guardsa moisture inhibitor e.g. Alminox should be applied. The conductor should be scratch brushedand greased prior to application of Line Guards used for tapping.

ApplicationJointing and restorative repair on conductors of aluminium, copper and galvanised steel.
ConductivityIn all cases - aluminium alloy, copper and galvanised steel - Heliformed® Line Splices will provideconductivity equal to, or better than, an equivalent length of unspliced conductor. To ensure agood long term joint, the conductor must be scratch brushed and greased prior to the applicationof the splice.
Holding StrengthOn all aluminium, copper and galvanised steel conductors of homogeneous stranding,Heliformed® Line Splices will hold a minimum of 90% of the ultimate tensile strength of theconductor as required by Australian Standard AS1154.1 - 2004.
CompatibilityAs Heliformed® Line Splices relateto their conductor materials -aluminium, copper and galvanisedsteel - problems due toincompatibility do not arise.
Installation PointersHeliformed® Line Splices shouldnot be reused after originalinstallation. Restorative repairshould be limited to damage inthe span and should not be usedat the point of support. Installationshould not be closer than 150mmto existing Armour Rods or LineSplice.

ApplicationFull Tension Splices have been designed for jointing ACSR. Two types of Full Tension Splices areavailable -
Type FTS - Multi Piece Construction - designed to hold both the inner steel core of theconductor, as well as the outer layers. This is of particular importance on conductors withgreased cores. Filler rods may be needed on 30/7 type conductors to bridge the gap betweenthe inner core and the outer strands, for attachment of the outer splice layer.
Type MSS - Multi Strand Construction - designed for installations on 3/4 or 4/3 typeconductors. The fitting is comprised of a mixture of galvanised steel and aluminium strands,which typically match the number and strength of those used in the conductor.
Rated Holding StrengthsOn ACSR conductors, FTS and MSS fittings will hold a minimum of 90% of the ultimate tensilestrength of the conductor as required by Australian Standard AS1154.1 - 2004. Splices should notbe reapplied after original installation.

ApplicationSpiral Vibration Dampers are designed to reduce aeolian vibration in conductors, generated bywind turbulence for conductors between 4.4mm and 19.3mm OD.Vibration control would be recommended in areas as follows:
• In Rural Areas
• Where are normally associated with top tie insulators
• Where spans exceed 107m and/or 15% tension 16oC
• As an important supplemental protection at deadends, also at Armour Rods, Helities®, SideTies and similar tangent support hardware
MaterialsSpiral Vibration Dampers are made of solid, non-corrosive high impact strength UV resistant PVCrod. Material withstands ambient temperatures in the range -40o to 70oC.
InstallationEngineering calculations are unnecessary for placement. The Gripping Section should be installedapproximately 100mm to 120mm from Deadends, Armour Rods or other conductor hardware.Generally, one Spiral Vibration Damper at each end of a span is adequate. However, for spansexceeding 245 metres (800 feet), two Spiral Vibration Dampers at each end of the span arerecommended.

Application1. For the reduction of static stresses at conductor suspension points and to provide greater
protection to conductors against the dynamic stresses of aeolian vibration.2. To give conductors protection against impluse and flash-over.3. To protect conductors against abrasion, bending and compression stresses. The protection
offered by HSU fittings is superior to armour-clamp combinations.4. To install line angles up to and including 30o and, through use of double units, up to 60o.
Materials• Bolt and Nut - Galvanised steel
• Split pin - Stainless steel, humpback
• Strap - High strength aluminium alloy
• Neoprene insert - Formulated for resistance to ozone attack, weathering and temperatureextremes. Design embodies aluminium alloy reinforcement moulded into the neoprene.
• Housing - For conductor sizes up to 9.9mm OD and for SC/GZ conductors, housings arepressed galvanised steel. For larger conductors, housings are high strength aluminiumcastings.

ApplicationBird Flight Diverters provide a visual image which helps birds avoid collisions with power lines.Studies show that proper installation of the flight diverters may reduce collisions by up to 90%.
MaterialsBird flight diverters are made from solid, non-corrosive, high impact strength, UV resistant PVCrod. The material withstands ambient temperatures in the range -400 to 700 and is orange in colouras this has proven to be most effective in terms of sighting by various bird species.
InstallationRecommended spacing for Bird Flight Diverters is 5 metres apart on each outer conductor phase,with one phase staggered at half a pitch out of line. In the case of Swan Flight Diverters,installation is recommended at a 3 - 5 meter spacing alternated evenly across all conductorphases.

ApplicationDulmison Low Voltage Spreader Rods are used to maintain the required midspan spacing of lowvoltage conductors and thus preventing clashing.
MaterialLow Voltage Spreader Rods are made from solid, non-corrosive high impact strength UV resistantPVC rod, or pultruded smooth skinned UV stabilised fibreglass. Material withstands ambienttemperatures in the range -400C to 700C and is white in colour.
InstallationThe spring clips are first fitted to the spreader rod at the required conductor spacings whilst onthe ground. The two legs of the clip are hand sprung towards each other to enlarge the holeopening, slid along the spreader rod into position and released. Using the appropriate safetyprocedures, the assembled spreader rod is laid across the conductors at the midspan location.The non-ring leg of the spring clip is first hooked under the conductor, followed by the ring leg.
