Outdoor H.V. Vacuum Circuit Breaker

ZW58type outdoor post-mounted high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is a kind of outdoor three-phase high-voltage AC switchgear with rated voltage of 10KV and rated frequency of 50Hz mainly used for breaking current, closing load current, overload current and short-circuit current in distribution network, which is applicable to the protection and control over the operation of substation, mines & other enterprises, and urban & rural power network, especially applicable to location with frequent operation requirement and automatization distribution of urban & rural power network. It uses the latest insulation solid closure technology in the world and has excellent ability to stand outdoor environment conditions. It is widely used by completely remove the incompatibility between miniaturization of vacuum interrupter and insulation requirement. Moreover, it has many advantages such as small size, light weight, beautiful appearance, free of maintenance and intelligent distribution.
