3 Phase Outdoor Switch Device 12kv Pole High Voltage Vacuum Circuit Breaker Model
ZW8-12 series of high voltage outdoor switchgear is used in three-phase AC power network of AC 50Hz, rated voltage 12KV for breaking and closing the rural network, city network and load current ,overload current, short circuit current for small scale power system. The overall structure of the product for the three-phase with whole box-type, and using the SMC insulation materials , , and it has reliable performance, high dielectric strength.
ZW8-12G is consist of ZW8-12 circuit breaker and isolation knife .and it is called conbination of circuit breaker.and also can be used segment switch,The series of ZW8-12,the mode of operation can be divided into manual and electric.
Town, country reform ideal equipment: It can be set with control mechanism to remote control, remote measure and adjustment.
Flexible operation, convenient: This product has performance of electric energy storage, electric close-open and hand energy storage, hand close-open, it also can be operated close or far remote.
Superior performance of open-shut: 30 times of open-shut short current at 20kA.
Small capacity of operation and high reliability: New designed small electric spring structure, parts numbers and operate capacity(about 30W) can be reduced to *** level.
Maintenance-free performance: Main breaker circuit and bivariate device, operate structure were all sealed in air of SF6(zero pressure)and not affected by outside.
Reliable sealability: It was used of mature seal structure technology and reliable capacity.
Special in-out line method: It was used silicon rubber pipe and make terminals distance sufficient, good insulator outside.
Safety in use: There was explosion proof equipment set on the top of box, even if breakdown inner, high temperature air or splash will not out.
Note: Due to continuous product improvement, the dimensions provided in this sample are for reference only. If necessary, our company can design and produce according to user requirements. Please contact the company in time.
