Transformer Bushings

transformatorski provodni izolatori

Construction is performed in conformance to DIN, BS and ANSI standards. They comprise the following groups of insulators:

1 – 3 kV 250 – 7000 A
10 – 30 kV 250 – 4500 A
45 kV 1000 – 3150 A
24 – 36 kV 5000 – 8000 A
24 – 36 kV 12500 – 25000 A
72,5 – 125 kV 1250 – 2000 A.

Besides standard insulators, there are insulators with elongated oil part, as well as with the elongated creepage distance for the operation in polluted conditions. Manufacturing material is mass C-110. Dimension tolerances are in conformance to DIN 40680A; they are tested in conformance to IEC-137. Metalization can be done at buyer’s request.
