AC bushings type GOH

GOH is a 36 kV high current, oil impregnated transformer bushing for oil-air application, normally used for generator step-up transformers. Current rating is up to 25 kA and its design facilitates use in bus duct arrangements with high temperatures.

GOH can be installed in any angle from horizontal to vertical, and is equipped with a 2 kV test tap. Connection is done to terminal plates on both air side and oil side.

 

Product scope:

  • Voltage: 36 kV
  • Current: ≤ 25 kA
  • Technology: Oil impregnated paper (OIP) with porcelain insulator
