• MICAFIL HIRIP bushings build on 100 years of experience to deliver total safety and reliability over an extended service life that ensures maximum asset availability.
• Standard and customized designs offer the flexibility to suit a wide variety of customer applications, while the bushings remain partial discharge free even when operating at twice the nominal service voltage.

ABB Switzerland’s MICAFIL bushings factory, based in Zurich, developed the first Resin Impregnated Paper (RIP) bushings in the 60’s, along with traditional OIP (Oil Impregnated Paper) and RBP (Resin Bonded Paper) bushings. Subsequently, we were the first company worldwide to start production of 420 kV RIP bushings at the end of the 80’s and 550 kV RIP bushings in 1996. Today, and for the last 30 years, we have exclusively produced RIP bushings. The latest new paperless RIS (Resin Impregnated Synthetics) technology launched in 2012.
ABB Switzerland Ltd, Insulation and Components has access to comprehensive resources, especially in the areas of high-voltage engineering, materials research and applied physics. The continuously improved design of our RIP high voltage bushings sets new standards regarding quality, reliability and safety.
We would like to support electrical utilities with achieving increasingly efficient performance of their assets, in addition to the ambitious targets of improved availability, higher safety standards
MICAFIL RIP bushing advantages• Excellent electrical and thermal properties• Partial discharge-free up to double
service voltage• High temperature resistance (class E, 120°C)• Low dielectric losses (tan δ ≤0.40 %)
Superb design• Compact conductor design• The materials are selected to provide the lowest
possible environmental impact over the whole product life cycle
Highest operational safety• Installation, transportation and operation
permitted in any position• Completely dry bushing, meaning no oil leakage
and lowest risk of explosion
Maintenance free• Maintenance and inspection-free bushing• A measuring tap allows for the assessment of
the insulation condition (capacitance and dissipation factor)
Standards• MICAFIL RIP high current bushings are specified
and tested according to the latest IEC 60137 (2017) and IEEE C57.19.00/01 (2000) standards
Benefits of the HIRIP series• Reduced number of components• High mechanical rigidity• Operation at low temperatures, down to -60°C• No joints (welding/brazing) in the current path
straight-through design• Smooth transition from the round hollow
conductor to the parallel terminals reduces the electrical resistance
• The integrated terminal pads of the conductor guarantee a better current distribution in the aluminum conductor
• Very long creepage distance • Integrated cooling ribs, mechanically protected
and cost reduction. Most utilities worldwide now recognize that our RIP technology makes a valuable contribution to achieving overall better performance figures. It is well worthwhile taking a brief look at the technical details of MICAFIL’s RIP technology.
MICAFIL RIP bushing technology The bushing condenser body consists of a solid core, made of wound crepe paper and inserted aluminum foils for electrical field control. The paper winding is vacuum dried and subsequently impregnated under vacuum with a high-temperature epoxy resin.
Vacuum drying, the impregnation of the paper winding with epoxy resin, and the final curing are very sensitive processes. They are carried out under vacuum in a controlled and hermetically sealed environment.
We are proud of our leading position in this technology field, providing our customers with profound expertise in the latest state-of-the-art technology, based on over 120,000 RIP bushings successfully in operation.

—Operating current diagrams
The rating plate current value, also given in the designation of the MICAFIL high current bushing, is a reference current and not the permissible current for the bushing. The permissible current depends on the temperature conditions around the bushing. Based on the temperature of the surrounding transformer oil and the ambient temperature of the air side of the bushing, one can calculate the permissible current by using the diagrams in Fig. 100 to 117.

Tair – maximum daily mean ambient temperature on the air side of the bushing. This depends on the type of installation. Usually, a busduct is used to encapsulate the bushing.
Toil – maximum daily mean temperature of the oil around the bushing (With forced cooling Toil is often relatively low compared to the maximum allowed temperature given in transformer standards).
L6 – current transformer extension
f – 50/60Hz
If all the connection pads are not occupied, the current could be limited, since the neighbour conductor will also influence the thermal behavior of the bushing.
—Condenser cores with a max. length of 9m can be produced.
