AC bushings type GSA-OO

GSA-OO is a dry resin-impregnated transformer bushing for oil-oil applications and is available for voltages from 72 to 245 kV. Current ratings are available from 1,600 to 2,500 A.​

The GSA bushing can be installed at any angle from horizontal to vertical and is equipped with a 2 kV test tap. Conductor arrangement can be either of draw lead or solid rod type.​

• The bushing is partially discharge-free and has a very low dissipation factor, which results in a lifetime equal to that of the transformer.​
• Unique sealing system RIPCOAT drastically reduces the risk of moisture ingress during handling.​
• 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: 72 - 245 kV
• Current: ≤ 2500 A. Higher current ratings on request.
• Technology: Resin impregnated paper (RIP)
