—RIP insulation

Capacitance graded 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 MICAFIL RIP (Resin Impregnated Paper) system consists of wound strips of crepe paper. Aluminum foils are wrapped in graduated lengths at calculated points.

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

ABB MICAFIL has developed its expertise over decades and gained market experience as a first-class supplier. This means that ABB RIP bushings have very good thermal and chemical resistance as well as high mechanical strength and stiffness.

—Today’s technology for tomorrow

—OilRIP stands for quality and versatility

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

The MICAFIL OilRIP 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 in our electrical testing laboratory.

Advantages of MICAFIL bushings

• Partial discharge-free up to double phase to ground 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).• These are completely dry bushings, meaning

that there is no risk of an oil leakage or explosion.

• No maintenance or constant monitoring necessary.

• Transport and storage is possible in all positions.

• Flexible design allows adaptation to different customer needs and transformer requirements.

• Easy and safe installation.• Proven reliability.

— Insulating core

The heart of the OilRIP bushing is its RIP insulated condenser core that has 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. Their high quality allows for the delivery of partial discharge free bushings up to double service voltage. To accommodate current transformers, the lower core part can be extended in steps of 100 mm up to 600 mm. The insulation length in the 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

The new flange has an optimized design to withstand high load and ensure mechanical robustness. With a multiple O-ring system, the transition between core and flange is oil- and gas-tight. The aluminum alloy used for this purpose is corrosion-resistant and mechanically robust. This ensures safe handling of bending moments during operation and in bending test loads. The whole series is type-tested in an accredited independent lab in accordance with the highest bending load class of IEC 60137 (2017).

Standard flanges meet the most commonly used dimensions, however dimensions modifications can be implemented. On request, it is possible to

select a double plate flange. In fact, the OilRIP bushings are designed in order to ensure perfect interchangeability of single plate and double plate flanges in the same compact dimensions. The flange is equipped with a test tap and has a de-aerating screw. The flange is mounted with an identification tag, M12 connection thread for flange earthing and, on larger bushings, eyebolts for lifting purposes.

— Transformer oil side end

ABB’s design allows the installation of bushings without shield electrodes for cable and rod conductor applications up to 170kV. Shield electrodes can be ordered as an option. In all other cases, a removable shield is provided which can be easily and safely installed by a bayonet locking system. ABB’s shield electrodes are designed using the most advanced methods and technologies.

— Cable side oil terminal and clamping system

The OilRIP bushings are designed for easy and safe installation. The ABB MICAFIL clamping system is well proven to remove the cable bolt or the rod by simple operations. It is also possible to position the cable bolt or the solid rod conductors within +/-10mm from the nominal dimensions. The terminal is a round blank full material copper piece that can be part of a cable bolt, a rod or a fixed conductor. The fixing devices also mean that there is no displacement or rotation of the terminal and conductor during installation and operation. The cable side connection is shielded by a removable shield, which is installed by a bayonet locking system. Variances in lateral access are possible on request. In this case, a customized safe and easy solution is provided in accordance to the ABB MICAFIL highest standard of quality.

—OilRIP bushings in detail

Current dataThe type designation of the bushings contains the standard current according to IEC 60137 (2017). The actual permissible operating currents depends on the lower part extension, L6, and in the case of the cable bolt conductor, on the type of insulation.

Oil side terminalThe standard air side terminals mentioned in the data tables cover the entire current range of the bushing.

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

C = T–20 mm

∅B

T = Length of cable bolt diameter

Removable solid rod conductorIn order to achieve higher operating currents, the bushings with a central tube are equipped with an additional removable solid rod conductor.

This type allows for the use of a single piece conductor without contact junctions which guarantees high current rating and excellent thermal performance. The oil gap is designed to keep the RIP core at a safe temperature, as proven by tests. Conductor installation and de-aeration of the central tube are similar in both versions either with solid rod conductor or with a cable bolt conductor.

ABB offers 3 types of conductors optimized for the selected current rating.

Recommended option

Cable bolt for draw leadThe current is led through a multi-stranded flexible conductor that is joined to the terminal of the winding. The lead is drawn up through the central tube of the bushing and the top connector (cable bolt) is fastened to the bushing clamp. In the standard model, the cable side terminal is a round, blank copper bolt. 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. Transformer manufacturers must provide the conductor cable with a thin insulation in order to keep transient voltages to the central bushing tube. The use of high temperature insulation allows for the increase of maximum operating current.

Fixed conductorBushings with a directly wound and non-removable conductor are suitable for high currents.

The transformer should have a 'manhole' to insure the access to the connection.

F

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).

Alternatively it is possible to withstand overload by improving cable insulation for draw lead. The present design allows safe temperature of the RIP even at higher current, by selecting aramid paper insulation with the support of ABB expertise.

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.

Type designation

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 clearance distances (A) to grounded transformer parts under standard conditions.

Recommended distances A from earthed parts (e.g. transformer wall).

As an option, ABB MICAFIL provides transition connectors for continuous voltage measurements. This is highly recommended in oil-oil applications to allow measurements in safe conditions from extern turret wall.

Routine and type testsThe standard routine tests are carried out in accordance with IEC 60137 (2017) with all the protocols supplied. Tests carried out according to other standards are available upon 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 OilRIP portfolio and were successfully passed in an accredited independent lab. Bushings always fulfill MICAFIL high quality standards, which are stricter than IEC an IEEE. Protocols can be supplied to customers on request.

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