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​
