Product Description
3150A Outdoor Circuit Breaker For High Voltage Gis Circuit Breaker Porcelain Type
Quick Detail: Best quality AC outdoor 3150a 69kv sf6 circuit breaker
Introduction of Products
H.V. A.C.porcelain type SF6 gas circuit breakers, with voltage from 70-140kV and rated current up to 3500A.
Three kinds of operating mechanism, pneumatic, spring and hydraulic type can be customized. Motor is used in spring mechanism to charge closing spring and charge opening spring at closing. Disk spring is used in hydraulic mechanism to be charged instead of traditional compressed nitrogen gas for charge, and hydraulic driving is used at both opening and closing.
Compressed air is used in pneumatic mechanism as driven force for open while spring is used for close. The three kinds of operating mechanisms have their own features and are used in circuit breakers of different voltage class respectively. Due to the unit structure in circuit breaker, there are advantages of minimized number of breaks, lower number of parts, simple structure, high reliability and long period of inspection.
