AC bushings type GSB
GSB is a dry resin-impregnated transformer bushing for oil-air applications and is available in 245 to 800 kV voltages.
The GSB can be installed at any angle from horizontal to vertical and is equipped with a 2 or 20-kV test tap. The conductor arrangement is of the draw rod or draw lead type.
- Our unique draw rod system facilitates easy field installation and removal without lowering the oil level.
- The bushing is free from partial discharges and has a very low dissipation factor, which results in a lifetime equal to that of the transformer.
- The insulator sheds are made from high-temperature vulcanization (HTV) silicone for unsurpassed erosion resistance.
- Excellent performance in seismic active areas.
- A comprehensive testing program has been performed in addition to what international standards require.
- It is possible to use alternative insulating fluids.
Product scope:
- Voltage: 245 - 800 kV
- Current: ≤ 2500 A. Higher current ratings on request.
- Technology: Resin-impregnated paper (RIP) with silicone or porcelain insulator
