ZW8-12G/630-20 high voltage parts of vacuum circuit breaker


Summary

ZW8-12 series vacuum circuit breaker for a period of 12 kv, rated voltage of the three-phase ac 50 hz high voltage outdoor switchgear equipment, mainly used for breaking off site, city network and small power system load current, overload current, short circuit current.

The product overall structure for the three-phase together box type, three-phase vacuum arcing chamber placed in a metal cabinet, using SMC insulating materials and insulation and insulation to ground, reliable performance, high dielectric strength.

ZW8A - 12 by ZW8-12 circuit breaker with a combination of the isolation knife, called a combination circuit breaker, can be used as the section switch. The series of products of operating mechanism for CT23 spring energy storage type operating mechanism, divided into electric and manual.


Product feature

City, the ideal equipment of the rural electric reform: Can be matched with the controller to realize remote control, telemetry and remote setting, and realize the four remote functions.
Flexible operation, convenient: This product is a east electric energy storage, electric points, both hand machine, manual and combination, and be able to close or long-distance remote control operation.
Open circuit superior performance: The breaking short circuit current 20 ka for 30 times.
Operating power is small, high reliability: New design of small electric spring mechanism, part number and operation work around (about 30 w) is reduced to the lowest level.
