high voltage insulation sleeving

high voltage insulation sleevingmade by Beijing Nobbel Electrical Tech Develop Co., Ltd. is used for enabling the high voltage conductor to pass through a wall or a floor, and insulating the conductor from them. It is usually used in a indoor power station etc. The high voltage insulation sleeving is different from other similar products at home and abroad. With reasonable design, novelty structure, aesthetic configuration and silicon rubber outer insulation sleeve umbrella group, the wall bushing has no oil, no ceramic, no gas, is convenient for operation and maintenance. 1. Advantages: Dry-type insulationNo oilfilling, no gasfilling, no ceramicHigh ability of antipollutionEasy operation and maintenance 2.
