72.5kV, 126kV, 145kV, 252kV SF 6circuit breaker

Product Description

Main features: 1. LW*5 serial circuit breaker is designed with latest development of self-energizing theory that the arc generated in the chamber is distinguished at a specified time with a part of energy from the arc itself. The arcing charmber of LW*5 erial circuit breaker is so constructed on the basis of resent research of electric and gas flow ield that high arc quenching efficiency and operation reliability is achieved. The force needed outside for breaking operation of the circuit breaker is greatly reduced for the arc itself contributes one part of enegy used for arc clearance, and appliacation of compact spring operation mechanism becomes reality. 2. the maximum rated current for *2.5kV and **6kV circuit breaker is up to ***0 Amps with a *0kA short circuit breaking curren while the maximum rated current is up to ***0 Amps with a *0kA short circuit breaking current. 3. *2.5kV and **6kV circuit breaker of LW*5 serial are three pole gang operation with a common motor drive, spring charged mechanism while each pole of **2kV circuit breaker is equipped with a motor drive, spring charged mechanism to realize single-pole operation or three-pole electrical gang operation. 4. the motor drive, spring charged mechanism is features of: Compact and simple construction Low opeartion noise High reliability No leakage, perator and environment friendly design
