Mostly purpose
the zw7-40.5.zw30h-40.5 outdoor hv electrical equipment on three-phase ac50hz it is used for controller and protecting 24~40.5kv transmission and distribution system ,it can also be used for network interconnecting breaker and switching capacitor bank. matching with segmentation controllers and automatic circult reclosers ,the product realizes intellectualized segmentation and reclose control of power systems ,annexing a current transformer inside,it provides measurement and protection.matching with spring or electromagnetism opereting mechanisms.the breaker has high reliability of mechanical property and can be operated frequently,it has no burning and explosion hazard,the breaker conforms to standards GB1984-1989 AC HVbreaker and IEC56,IEC62271-100HV AC breaker,the breaker’s main feature:excellent brek performance,long mechanical life up to 10000 times,simple structure,non maintenance,excellent insuiating property and strong anti soll performance.according to customer’s it can install current transformers inside.the measuring accuracy will be level of 0.2, and it realizes three-phase interaction protection
