AC bushings type GOH
GOH is a 36 kV high current, oil-impregnated transformer bushing for oil-air application, generally used for generator step-up transformers. The current rating is up to 25 kA, and its design facilitates use in bus duct arrangements with high temperatures.
GOH can be installed at any angle from horizontal to vertical and is equipped with a 2 kV test tap. Connection is done to terminal plates on the air and oil sides.
Product scope:
- Voltage: 36 kV
- Current: ≤ 25 kA
- Technology: Oil-impregnated paper (OIP) with porcelain insulator
