GSA-OA is a Resin Impregnated Paper (RIP) bushing with Silicone Rubber (SiR) insulator oil-air applications. The condenser core is bonded directly to the silicone rubber to give a compact and lightweight bushing containing no gas, oil, or other liquids. 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.​

Key Technical Features:

  • The GSA bushing is partially discharge-free and has a very low dissipation factor, which results in a lifetime equal to that of the transformer.​
  • The unique sealing system RIPCOAT drastically reduces the risk of moisture ingress during handling.​
  • The insulator sheds are made from high-temperature vulcanization (HTV) silicone for unsurpassed erosion resistance.​
  • The GSA bushing has an 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.​
