WJ01系列真空灭弧室 
　

该系列真空灭弧室采用陶瓷绝缘外壳，具有灭弧能力强，性能可靠，寿命长、体积小、无爆炸危险，不污染环境等优点，比空气开关的电寿命长十余倍之多。配套相应的真空接触器可用于电力、冶金、矿山、化工等部门及住宅小区配电系统作控制和保护及无功补偿用，特别适合需频繁操作的场所。
SERIES WJ01 of VACUUM INTERRUPTER 

This series of vacuum interrupter is the ceramic insulating envelope, It has the advantages of small size, strong arc-quenching capability, long life, and reliable property as well as no risk of explosion, and no pollution, its operating life is ten more times than air switches . Matched with the accordant vacuum contactor, it can be used in the electric power, metallurgical, mine and chemical department and uptown to control and protect the transmission and distribution system, and it can be also used for reactive power compensation. It is especially suited for use in the place where it is operated frequently.
