AC Bushing type GOEK (245-8000 kV, ≤ 5000A)

GOEK is an oil impregnated transformer bushing for immersed oil-SF6 or oil-oil application. It is available for voltages from 245 to 800 kV and maximum rated current of 5,000 A. The types up to 550 kV are equipped with an oil expansion system which facilitates installation at any angle from horizontal to vertical without any special precautions.

All models are equipped with a 20 kV test tap and the conductor arrangement can be either of the draw rod or tight bottom contact type. To detect possible gas leakage, the bushings can be equipped with a pressure monitoring system.
