Simense Substation Disconnecting Switch vacuum contactor 7.2KV

Product Overview

Description

Simense Substation Disconnecting Switch  vacuum contactor 7.2KV

 

Our CKG series alternating current vacuum contactor have adopted international prevalent up-down layout, convenient to use and maintain for the reason of small size, light weight and low noise, easily apt to make-up F-C circuit complete set of equipment. They are especially appropriate to frequent operation places to direct or distance connect or break the main circuit in the area of coal, petroleum, chemical industry, metallurgy, electric power, mechanical, transportation and so on.
