The bushing in principle (for example: bushing for cable conductor)

Insulating coreThe heart of the AirRIP bushing is its RIP insulating core, with capacitor inlays for electric field control. The production of RIP is based on time-tested and proven technology. Complex production processes compress the material into a compact, liquid- and gas-tight insulating core, which complies with current partial discharge and temperature requirements.

To accommodate current transformers, the lower core part can be extended in steps of 100 mm up to 600 mm. The short oil side is consistent with our proven and balanced dimensioning, and optimizes the strength of the interface between the insulating core and transformer oil. These dimensions also guarantee a high level of interchangeability with older bushing types.

Flange and insulatorThe insulator is the supporting part of the bushing and takes over the mechanical loads with the two integrated fittings, head and flange. The flange not only holds the insulating core, it also forms the lower fitting of the insulator.

With a multiple O-ring system, the transition between core and flange is oil-and gas-tight. The aluminium alloy used for this purpose is corrosion-resistant and mechanically robust. This ensures safe handling of bending moments during operation or in bending test loads. The whole series is designed and type-tested in accordance with the highest bending load class of IEC 60137 (2017).

The standard flange plate bolt circles conform to currently common dimensions, although variations can easily be implemented. The flange is equipped with a test tap and has an opening (M12) with a closure screw that can be used to de-aerate the transformer or as a connector for a Buchholz relay. Also mounted on the flange are: identification tag, connection thread M12 for flange earthing and, with larger bushings, eyebolts for lifting purposes.

The head of the bushing closes the bushing and carries the current conductor fixing. The 420 kV and 550 kV bushings have a separate shield to avoid external corona discharges.

Oil side end The shape of the opening ensures that no shield electrodes are required up to 73 kV. We offer shielding as a variant.

From 123 kV, depending on current conductor version, either fixed shields (cable conductors) or removable shields (rod conductor and fixed conductor) are used, which are attached to the end of the bushing. They prevent the excessive use of transformer oil and facilitate the assembly of the conductor insulation beneath the bushing.

ABB's shield electrodes are dimensioned using state-of-the-art methods and their surface is provided as standard with a high-quality solid insulation layer.

Please note our installation recommendations.

—The AirRIP bushing in detail

RIP insulationCapacitor bushings enable control of electric field distribution in radial and axial directions by inserting conductive layers in the insulating core. The insulating core of the RIP (Resin Impregnated Paper) system consists of wound strips of crepe paper. Aluminium foils of graduated lengths are wrapped at exactly calculated points.

The wrap is heated, vacuum dried, and impregnated and cured under vacuum with an epoxy resin formulated by ABB. The impregnation process requires the skilful setting and control of process parameters, as well as broad knowledge and experience in the field of materials science and materials selection.

ABB has developed its expertise over decades, and gained market experience as first-class supplier. The result is RIP bushings with very good thermal and chemical resistance and high mechanical strength and stiffness.

Dry bushingsIn line with our product philosophy of compact design and dry bushing (neither liquid-filled nor liquid-insulated), the space between the major insulation and insulating envelope is filled with the time-tested MICAGEL dry filler. MICAGEL is poured in a liquid form into the bushing and becomes compressible and dry after curing.

Outer insulationPorcelain has proved its worth as a material for outer insulation over decades. More recently, composite hollow insulators have gained market maturity as an alternative material. These silicone composite insulators offer reduced weight, easier handling, and explosion safety characteristics. We can offer AirRIP bushings with silicone composite insulators as well as with traditional porcelain insulators.

AirRIP stands for quality and versatilityHigh-voltage bushings must meet the highest standards of operational safety, and minimize risk of for people and property. Growing environmental awareness and regulation requires low-impact production and clean operation.

The MICAFIL AirRIP series meets these requirements thanks to high-quality materials and reliable processing techniques. ABB maintains high technical standards, and regularly reviews development and manufacturing processes. We ensure high product quality through comprehensive testing during production and in the electrical testing laboratory.

Advantages of MICAFIL AirRIP technology• Partial discharge-free up to double service voltage• High temperature resistance (class E, 120 °C)• Low dielectric losses (tan δ ≤ 0.40 %)• High flexural strength – ‘heavy load’ according to

IEC 60137 (2017)• Completely dry bushing, meaning no oil spills and no

explosion risk• No maintenance or constant monitoring necessary• Transport and storage is possible in all positions• Flexible design allows for adaptation to different customer

needs and transformer requirements.

Medium currents with removable rod conductorFor improved current utilization, the bushing with central tube is equipped with a removable copper conductor rod.

In the standard model, the air side terminals are bare. As an option, the surfaces can be silver- or nickel-plated, and the shapes of the terminals can be selected. The rod conductor can be fitted with a joint, usually near the flange. Various terminal shapes are available for the lower end. Conductor installation and de-aeration of the central tube are similar in both the version with rod conductor and with cable conductor.

Please note: The rod conductor is a separate component and must be selected separately.

High currents with fixed conductorBushings with a directly wound and non-removable conductor are suitable for high currents. Various terminal solutions are available (see data tables and figures).

Current dataThe type designation of the bushings contains the standard current according to IEC 60137 (2017). The actual per mis sible operating currents depend on the lower part extension L6, and are shown in the data tables.

Air side terminalThe standard air side terminal mentioned in the data tables covers the entire current range of the bushing.

Guidelines for the dimensions of air side terminals:

Maximum permissible ∅d2 Lengthc2 operating current (A)

1,600 30 80

2,500 40 125

3,500 50 125

4,300 60 125

5,000 flat 90 × 105 thickness 30

If the full current range of the bushing is not utilized, smaller dimensions may be used as an option, as long as the above rules are observed.

Overload If overload capacity is required for the transformer, according to IEC 60076-7 (normal load cycles), the rated current of the bushing should be chosen with at least 120 % of the transformer-rated current, in accordance with IEC 60137 (2017).

The rated current is the starting point for choosing the type of conductor. However, current levels of conductor types partially overlap and can be selected according to individual preferences. Please follow the appropriate icons when making your choice.

The choice of insulator type has no influence on the performance of the bushing.

Please note corresponding weights as well as head and shed diameters for each insulator type.

Silicone composite insulators made of glass fibre- reinforced tube with helical or straight shedsHydrophobicity, and the ability to transfer these properties to foreign layers as well, is the most important value-added feature of these insulators. They offer many advantages: • Excellent contamination behavior due to hydrophobic

surface properties and low leakage currents• Improved safety for personnel and equipment• Lower weight.

The helical shed is the result of intensive development efforts at ABB. Outstanding results in tough long-term pollution tests have proved their quality (certificates available on request).

Insulators with conventional straight sheds complement our product range.

Porcelain insulators made of high-quality electrical porcelain, brown and grey High-quality electrical porcelain – an excellent, proven material over decades– is available in the standard color brown and alternatively in light grey.

Creepage distancesAll types of insulation are made with alternate shed profiles.Creepage distances are measured for the high pollution requirements of IEC 60815:

Low currents with cable conductorThe current is led through a multi-stranded flexible conductor, joined to the terminal of the winding. The lead is drawn up through the central tube of the bushing and provided with the top connector (cable bolt) that is fastened to the bushing head. In the standard model, the air side terminal is a round, bare copper bolt. As an option, the surfaces can be silver- or nickel-plated, and other terminal sizes can be selected. To avoid unnecessary contact junctions, the draw lead bolt is of a single-piece design. A tried-and-tested fixing device with few parts ensures that no inadvertent displacement in axial direction or twisting is possible. It also allows positioning of the cable bolt to within ± 10 mm from nominal dimensions. Transformer manufacturers must provide the conductor cable with a thin insulation in order to keep transient voltages to the central bushing tube.

Test tapEach bushing is equipped with a standard test tap. The test tap is connected to the outermost capacitor foil and is always grounded during operation. For measurement, the cap must be unscrewed and the supplied 4 mm plug coupling must be inserted.

As an option ABB provides transition connectors for continuous voltage measurements.

Routine and type testsThe standard routine tests are carried out in accordance with IEC 60137 (2017) and the protocols are supplied; tests according to other standards are available on request. The type tests were performed on representative bushings in accordance with current standards IEC 60137 (2017), and IEEE C57.19.00 (2004) / C57.19.01 (2000). These tests cover the entire AirRIP portfolio and were successfully passed in the presence of an independent observer from KEMA. Protocols can be supplied to customers on request.

Packaging and storageThe bushings are packaged and sent in a dry and clean state. On request, we offer long-life packaging. The bushings can be transported and stored without the constraints on orientation that liquid-filled or liquid-insulated bushings have.

Each AirRIP bushing meets all requirements of IEC 60137 (2017) and the electrical values under IEEE C57.19.01 (2000).

Recommended installationOur bushings are designed and tested for mineral oil appli cations. The field strengths in oil on the lower part of the bushing depend on the shape of the surrounding parts, as well as on the quality and condition of the transformer oil. As a guideline, the following table shows the respective distances A to grounded transformer parts under standard conditions. They are valid for the oil side ends (standard and variants) as per the data tables. Due to limiting conditions additional insulating measures or larger distances may be necessary. Uninsulated edges around the bushing should be rounded to Rmin = 5 mm. The diameter of the current conductor should be at least half of the inner tube diameter d3. Oil access in the central bushing opening and in the open space of the shield electrodes must not be obstructed.
