ZW20-12 outdoor high voltage AC vacuum Sf6 circuit breaker from China
Product Overview
ZW20 series circuit breaker use three-phase non-segregated structure and has the features of stable and reliable breaking performance, no combustion and explosion danger, maintenance-free, light weight (two-thirds of similar products ), high cycle life (mechanical operating life is 10000 times) and so on. New designed spring operating mechanism is exposed in SF6 to effectively avoid traditional spring operation mechanism’s design defects, such as stagnation and rustiness, making a significant improvement in reliability.
Product Features
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;
2.Open circuit superior performance: the breaking short circuit current 25 ka 30 times;
3. Small operation power, high reliability, the miniaturization of newly designed electric spring mechanism, parts number and energy-storage motor is rated power (about 40 w) is reduced to the lowest level;
4.Flexible installation method: column can be used on lifting or sit installation;
5.Maintenance-free characteristics: the main loop of the circuit breaker, the secondary components, operating mechanism are sealed in SF6 gas gauge pressure (zero), is not affected by the external environment, stable performance, reliable, maintenance free;
6.Sealed performance is reliable, the sealing structure of mature technology, reliable sealing;
7.Into the line has a good performance of insulation: adopt silicon rubber casing, insulation between the terminals from abundant, good performance of insulation outside the use of safe;
8."Four control" function, can be matched with the controller, realize the remote control, remote sensing, remote and remote adjustable function.
