AC bushings type GOB

GOB is an oil impregnated transformer bushing for oil-air application, for voltages from 52 to 300 kV with a maximum rated current of 1,250 A.

All models are equipped with a 2 kV test tap and the conductor arrangement can be either of draw lead or solid rod type. The GOB can be installed with an inclination of up to 45° from the vertical without any special precautions.

Product scope:

Voltage: 52 - 300 kV
Current: ≤ 1,250 A
Technology: Oil impregnated paper (OIP) with porcelain insulator
