4 AirRIP / RTKF 24550 kV | Micafil Transformer Bushings

Micafils AirRIP outdoor transformer bushings are the product of a sophisticated design using a small number of components: insulating body, main flange, insulator shell and current conductor. They are produced in a wide variety of designs and thus can easily fulfil specific customer requirements. AirRIP bushings are completely dry, pressurized, explosion-proof, fire-resistant and allow high application temperatures.

RIP insulation

Capacitor bushings enable control of electric field distribution in radial and axial directions by inserting conductive layers in the insulator body. The insulating body of the Micafil 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, as well as impregnated and cured under vacuum with an epoxy resin formulated by ABB. The impregnation process requires high skills in setting and in the control of process parameters, as well as a broad knowledge and experience in the field of materials science and in materials selection.We have developed our 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 bushings

In line with our product philosophy of compact design and dry bushing, the space between the insulating body and insulator is filled with the time-tested dry filler MICAGEL. MICAGEL is poured in a liquid form into the bushing and after curing forms a compressible dry filling.

Outer insulation

For decades, porcelain has proved its worth as a material for outer insulation. With the development of composite hollow insulators in recent decades an alternative has gained market maturity. Our customers appreciate the benefits these offer, such as reduced weight, easier handling, and the explosion safety characteristics of these silicone composite insulators. We offer the AirRIP bushings both with silicone composite insulators as well as with porcelain insulators.

AirRIP stands for quality and versatility

High-voltage bushings must meet the highest standards of operational safety and minimize the risk of damage for people and facilities. The greatly increased and growing environmen-tal awareness requires gentle production and clean operation.The Micafil AirRIP series meets these requirements thanks to high-quality materials and reliable processing techniques. The technical standard is very high and development and manu-facturing processes are regularly reviewed. High product qual-ity is ensured with 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 < 0.35 %) High flexural strength, heavy load

according to IEC 60137 (2008) Completely dry bushing, i. e., no oil spills, 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

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

Insulating bodyThe core of the AirRIP bushing is the insulating body of RIP with capacitor inserts for electric field control. The produc-tion of RIP is based on time-tested and proven technology. Complex production processes compress the material into a compact, liquid and gas-tight insulating body, which com-plies with current partial discharge and temperature require-ments.To accommodate current transformers, the lower body 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 body 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 body, it also forms the lower fitting of the insulator. The con-nection to the transformer takes place via the flange plate bolted to the flange.With a multiple O-ring system, the transition between body and flange is oil-and gas-tight. The aluminium alloy used for this purpose is corrosion-resistant and mechanically robust. This ensures safe control of the bending moments in occur-ring operating stresses or in bending test loads. The whole series is designed and type-tested in accordance with the highest bending load class of IEC 60137 (2008).The standard flange plate bolt circles conform to currently common dimensions. Deviations can easily be executed as variants. 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 connector for a Buchholz relay. Also mounted on the flange: identification tag, connection thread M12 for the 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 exces-sive use of transformer oil and facilitate the assembly of the conductor insulation beneath the bushing.Our shield electrodes are dimensioned using modern methods and their surface is provided as standard with a high-quality solid insulation layer.Please note our installation recommendations.

The choice of insulator type has no influence on the perform-ance 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 also to foreign layers is the most important value-added feature of these insulators. They have many advantages: Excellent contamination behaviour due to hydrophobic

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

The helical shed is the outcome of intensive development efforts of ABB. Outstanding results in tough long-term pollu-tion tests have proven their quality (certificates 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 for decades an excellent, proven material is available as always in the standard colour brown and alternatively in light grey.

Creepage distances

All types of insulation are made with alternate shed profiles.Creepage distances are measured for the high pollution requirements of IEC 60 815:

Choice of insulator


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 respective icons when making your choice.

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 the positioning of the cable bolt to 10 mm from nominal dimensions.The manufacturers of the transformers must provide the con-ductor cable with a thin insulation in order to keep transient voltages to the central bushing tube.

Medium currents with removable rod conductorFor a better current utilization of the bushing with central tube, it is equipped with a removable conductor rod of copper.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 their 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 data

The type designation of the bushings contains the standard current according to IEC 60137 (2008). The actually per mis-sible operating currents depend on the lower part extension L6 and are shown in the data tables.

Air side terminal

The 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 Length c2 operating current (A)

1600 30 80

2500 40 125

3500 50 125

4300 60 125

5000 flat 90 105 thickness 30

In case the full current range of the bushing is not utilized as an option one may use smaller dimensions, as long as 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 trans-former-rated current, in accordance with IEC 60137 (2008).

Choice of current conductor


Each AirRIP bushing meets all requirements of IEC 60137 (2008) and the electrical values under the 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 the conditions 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. Uninsulate 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 elec-trodes must not be obstructed.

Type designation

Test tapEach bushing is equipped with a standard test tap. The test tap is connected to the outermost cap-acitor 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 we provide transition connectors for continuous voltage measurements.

Routine and type testsThe standard routine tests are carried out in accordance with IEC 60137 (2008) 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 (2008), 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. Proto-cols are 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 in any position.
