High Voltage Indoor Vacuum Circuit Breaker Protection Device 40.5kV Three Phase

40.5kV Indoor Vacuum Circuit Breaker with High Voltage Switchgear Equipment

1. ZN85-40.5 Indoor High Voltage Vacuum Circuit Breaker is three phase voltage 50Hz Power , 12kV Rate voltage power system indoor switch equipment . As grid Equipment and Electrical Equipment in Industrial and Mining Enterprises . Lend Itself to frequent Opration on Rate Voltage and Opening short Circuit Current .

2. The circuit breaker adopts an integrated design of operating mechanism and circuit breaker body , It can be used as a fixed installation unit or with a professional propulsion mechanism ,Role of component vehicle unit .

3. Altitude is after 2000M .

4. In terms of the mechanical life of the two types of cabinets, the mechanical life of the ring cabinets can only reach between 5,000 and 10,000(with an estimated life span of 5-10 years), while the mechanical life of the central cabinets can reach only 30,000(with an estimated life span of 30 years)(5) The price comparison shows that Huanwanggui(at Schneider's), with a load switch, is currently at about $4,000-50 ,000; The current price of the circuit breaker ring cabinet is about 100,000 yuan; The ring net cabinet with circuit breaker is more expensive than the central cabinet.
