Application of Cutout Switch ZW32-12

Combined with the disconnecting switch, it can be used as a section switch for switching off/on load current, over-load current and short circuit current in power systems. Its vacuum explosion chamber uses a patented sealing technique. Its external insulation uses silicon rubber pipes with long life, high reliability and weather ability. It is convenient to transport and has a high cost-performance ratio. Using a compact and high-reliability spring operating mechanism, the operating mechanism structure is simple and has a long life of up to 20000 times. 

If using advanced permanent magnetism mechanisms, it will have more reliable mechanical properties. And it can install a manual switch on/off mechanism to switch on/off in the field in need. Matching with controllers, the breaker can be an automatic circuit recloser to realize remote controlling, remote measurement, remote signalling and remote regulating. The product's features: are non-burning and explosion hazard, non-maintenance, small size, lightweight (less than 100kg), long life (more than 10000 times), safe and reliable, and simple operation and installation.
