AC Bushing type GOEK (245-800 kV, ≤ 5000A)
GOEK is an oil-impregnated transformer bushing for immersed oil-SF6 or oil-oil applications. It is available for 245 to 800 kV voltages and a maximum rated current of 5000 A. The types up to 550 kV are equipped with an oil expansion system that 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. The bushings can have a pressure monitoring system to detect possible gas leakage.
Product scope:
- Voltage: 245 - 800 kV
- Current: ≤ 5000 A
- Technology: Oil-impregnated paper (OIP)
