ZW8-12 series outdoor high-voltage vacuum circuit breaker rated voltage isolator 12kV, 3-phase ac voltage switchgears of outdoor.Mainly used for open circuit, close the load current power system, overload current and short-circuit current.Applicable to transformer substations and industrial enterprises in distribution system for protection and control, also applies to rural power grid and frequent operation. Total box adopts triple circuit breaker.Outer insulation USES silicone rubber, SMC, silicone hydrophobic good anti-aging properties, and have antioxidant properties, filthy lon advantages, and increase the outer surface creepage distance, effectively guarantee the product of insulation. The cabinet with composite insulation (dry insulation), the casing breaker can be installed two or five one coil currenttransformer, provide protection and measuring signal, can install isolating switch, level, flow controller, the linkage of circuit breaker, and can break-brake operations manual or electric, remote controller matching with operation and distribution automation, also can cooperate with coincidence controller is composed overlap.
