W20A-12kv Type Of Outdoor High Voltage 4 phase Vacuum Circuit Breaker

W20A-12kv Type Of Outdoor High Voltage 4 phase Vacuum Circuit Breaker Summary ZW20A - 12 / T1000 (630) - 25 type of outdoor high voltage vacuum circuit breaker (hereinafter referred to as breaker) for a period of 12 kv, rated voltage of the three-phase ac 50 hz outdoor distribution equipment. It adopts vacuum arcing and SF6 gas as insulating medium, is ZW20-12 column type vacuum circuit breaker on the modified products. Cabinet adopted the introduction of Japan's Toshiba VSP5 gas seal, explosion-proof, insulation structure technology, into the outlet duct and the seal performance is improved, the overall sealing performance is good, inside the filling of SF6 gas leakage, is not affected by the external environment, the miniaturization of spring operating mechanism, optimization design and reliability and stability, with straight moving chain initiative and multistage tripping system, operating reliability and stability than the domestic traditional spring operating mechanism for several times: the axis of the main loop and the contact between the adduction of the chain structure, main loop of the small contact resistance, low temperature rise. So, ZW20A - 12 column type outdoor vacuum circuit breaker is a maintenance free product, is the circuit breaker on the pillars.   Product feature 1.Flexible operation, convenient: this product can be electric energy storage, electric switch, can also be hand machine, manual, switching function, and can be close or far away from the remote control; Open circuit performance is superior, the breaking short circuit current of 25 ka for 30 times;
2. Operating power is small, high reliability: the new design of miniaturized electric spring mechanism, part number and energy-storage motor is rated power (around 40 w) reduce to the lowest level; Flexible installation, can be used in a column on lifting or sit installations; Maintenance-free characteristics: the main loop of the circuit breaker, the secondary components, operating mechanism are sealed in the SF6 gas pressure (zero table), not influenced by the external environment, stable performance, reliable, free maintenance;
