ZW7-40.5 series high voltage out door circuit breaker can be used for 50HZ 40. 5kv outdoor
ZW7-40.5 high voltage outdoor circuit breakerZW7-40.5 series high voltage out door circuit breaker can be used for 50HZ 40. 5kv outdoorhigh voltage electrical equipment. They are mainly used in controlling and protection of out doorpower transmission and transformation system of 35kv, also in normal operation and short-circuitprotection for all kinds of power grid and frequent operation place.Attached spring operating structure and electromagnet operating structure can manipulate electricopening and closing in a distance, or accumulate energy for manual operation. The designperformance strictly sticks to our national standard GB1984 - 89 for high voltage alternatingcurrent vacuum circuit breaker, and meet the requirements of International Electro technicalCommission (IEC) IEC-56 for high voltage alternating current vacuum circuit breaker. Theseseries of VCBs are ceramic pillar type. Vacuum interrupter is installed in upper part of ceramicinsulator. It has characteristics of well tightness and high temperature endurance, non-combustionand non-exploration, easy mounting, anti-aging and long service life.Ambient condition1. Altitude: up to 2500m2.
