bushings in operation all over the world
Siemens Energy - Your partner for the OIP IEEE market
Siemens Energy offers transformer bushings only for the IEEE market. These bushings are specifically designed, manufactured and tested according to IEEE standards and available from 25kV up to 500kV system voltages in the most common current ratings.
Trench Group & HSP – Your reliable partners for bushings
Trench Group & HSP are two of the largest bushing manufacturers in the world. They operate bushing factories in Germany, France and China. These factories manufacture a wide range of bushing products for power transformers, gas-insulated switchgear, breakers, generators, buildings, test equipment, rail road systems and other special applications.
Trench together with HSP – pioneers for dry type bushings – are leading bushing manufacturers in the world with a very broad portfolio.
Trench and HSP bushings are available in a wide variety of internal insulation technologies including
- Oil-impregnated Paper (OIP)
- Resin-impregnated Paper (RIP)
- Resin-impregnated Synthetics (RIS)
- Resin-impregnated Glassfiber (RIG)
- Ester-impregnated and
- SF6 gas.
They are available with a variety of external insulation materials including porcelains in brown or grey; Epoxy-resin for indoor applications and silicone rubber compounds for heavy pollution or high seismic areas.
A bushing is an electrical engineering component that insulates a high-voltage conductor passing through a metal enclosure or a building. Bushings are needed on:
- Transformers
- Buildings
- Air- and Gas-insulated switchgear (AIS/GIS)
- Generators
- Other high-voltage equipment
Whatever your requirement is, the Trench and HSP Group has the right bushing for your application.
