 ZW***0.5 series high voltage out door circuit breaker can be used for *0HZ *0. 5kv outdoor high voltage electrical equipment. They are mainly used in controlling and protection of out door power transmission and transformation system of *5kv, also in normal operation and short-circuit protection for all kinds of power grid and frequent operation place.

Attached spring operating structure and electromagnet operating structure can manipulate electric opening and closing in a distance, or accumulate energy for manual operation. The design performance strictly sticks to our national standard GB***4 - *9 for high voltage alternating current vacuum circuit breaker, and meet the requirements of International Electro technical Commission (IEC) IEC**6 for high voltage alternating current vacuum circuit breaker. These series of VCBs are ceramic pillar type. Vacuum interrupter is installed in upper part of ceramic insulator. It has characteristics of well tightness and high temperature endurance, non-combustion and non-exploration, easy mounting, anti-aging and long service life.
