Leading edge technology

Micafil brand products are the world leader in RIP techno-logy for oil-free, dry bushings

Micafil, based in Zurich, Switzerland 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 525 kV RIP bushings in 1996. Today, and for the last 30 years we have exclusively produced RIP bushings.

ABB Switzerland Ltd, High Voltage 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.

In general, the aim of electrical utilities is to achieve increasingly efficient performance of their assets, in addition to the ambitious targets of improved availability, higher safety standards 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 subse-quently impregnated under vacuum with a special 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 100 000 RIP bushings successfully in operation.

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 (tanδ <0.35%)

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

− Fire resistant with no explosion risk due to the oil-free design

Maintenance free

− Maintenance and inspection-free bushing − A measuring tap, which allows assessing the insulation

condition (capacitance and dissipation factor)

Standards

− Micafil RIP high current bushings are specified and tested according to the latest IEC 60137 and IEEE C57.19.00/01 standards.

Benefits of the HIRIP series

− Reduced number of components − High mechanical rigidity − Operation at low temperatures, down to –25°C − On request –60°C available − 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 − Integrated cooling ribs, mechanically protected − Very long creepage distance

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. 8 to 25.

Tair maximum daily mean ambient temperature on the air side of the bushing. This depends greatly on whether the bushing is enclosed or not, and if enclosed, on how the enclosure is designed.

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.

Type designation

The type designation for high-current bushings is made up as follows:HIRIP RTXF 36–200/11000

Reference current with current transformer extension = 0 mm, maximum daily mean oil temperature = 90 °C

and maximum daily mean air temperature = 70 °C in bus duct, frequency = 50Hz

Rated lightning impulse withstand voltage (BIL) [kV]

Rated voltage [kV]

R = RIP insulation | T = transformer application | X = length of oil side | F = air side

HIgh current Resin Impregnated Paper bushing

Ordering number

The ordering number comprises two parts:

Part 1

- Ordering type number, which specifies the bushing type

Part 2

- Ordering modifications number, which specifies the bushing options
