FCRG2-72.5kV dry-type wall bushing and higher. Such as 123kV,138kV, 145kV, 170kV, 252kV
The FCRG high-voltage dry-type wall bushing made by Beijing NOBBELelectrical tech develop Co., Ltd. is different from other similarproducts in China and abroad. With reasonable design, the producthas no oil, no ceramic, no gas. The product has new structure andbeautiful appearance with the silicon rubber skirts as the outerinsulation.
This product is used to enables HV conductor to pass through a wallor floor, and insulates the conductors from it. This product isusually used in indoor power station of 50Hz or 60Hz.
