ZW8-12 outdoor pole-mounted high-voltage vacuum circuit breaker

Type outdoor pole-mounted high-voltage vacuum circuit breaker) Main uses
Type outdoor pole-mounted high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor power distribution equipment with rated voltage and three-phase AC. It is mainly used for disconnecting and closing the load current, overload current and short-circuit current in the power system of the distribution network. It is suitable for protection and control in substations and power distribution systems of industrial and mining enterprises. It is more suitable for rural power grids and places with frequent operations. It is especially suitable for the needs of urban and rural power grid transformation.
This installation instruction manual stipulates the main technical parameters, product structure, and principles and methods of operation, installation, use and maintenance of the circuit breaker.
