High-Voltage Equipment
High-Voltage Transformer Bushings
High-voltage bushings are structural components of power transformers, oil-filled circuit breakers, shunt reactors, and gas-insulated switchgear (GIS). They are also used as standalone elements in indoor switchgear installations.
We offer high-voltage bushings with either polymer or porcelain external insulation, as well as the following types of internal insulation:
RIP insulation (RIP = Resin Impregnated Paper)
RIS insulation (RIS = Resin Impregnated Synthetic material)
The high-voltage bushings we offer are fully interchangeable with GKT and BRIT-type bushings.
They are available in a wide variety of shapes, designs, and sizes and are designed for different voltage classes and rated currents.
