Model meaning
ZW32 is the name commonly used to refer to the high-voltage outdoor pole-mounted vacuum circuit breaker unit, which is basically the "outdoor switch" of the power distribution network. It forms the main part of the power distribution network in the outdoor mode, which consists of three-phase AC 50Hz and a rated voltage of 12kV. Directly installed on utility poles, it is a device that can be used for sectionalizing, protecting, and controlling electrical systems.
Primary Features and Benefits
Outdoors-Only Model: The device is made for the outdoors and it can be used in any type of weather without fail or repair due to its sealing against wind, rain, snow, dust, and even sunlight, thus it can be operated reliably in any environment.
Vacuum Interruiper Technology: The vacuum interrupter chamber is also used in vacuum breakers like the ZN63 for the ZW32, which offers high breaking capacity, long service life, and zero risk of fire.
Short and Light: Either a three-phase shared enclosure or separate enclosures are used for the breaker so that it is small and light and the installation of the pole-mounted can be done easily.
Control Choices of Wide Range: An Electric spring operating mechanism can be equipped on it, and integration with controllers (FTUs) will enable the automation functions remote control, telemetry, and communication—thus the device is the main component in smart grid applications.
Non-Service Life: The vacuum interrupter is sealed thus it has a very long operational life, and virtually no maintenance is required.
