ZW20-12 outdoor pole vacuum circuit breaker is a three-phase AC 50Hz, 10kV outdoor high-voltage switchgear. It is mainly used in medium-voltage overhead line power grids. For overload current and short-circuit current. This product adopts vacuum arc extinguishing and SF6 gas insulation. The inlet and outlet insulation sleeves are integrally cast by epoxy resin and silicone rubber. In order to reduce the switch volume, corner sleeves are used for A and C phases to ensure good external insulation.
Can be equipped with spring operating mechanism or permanent magnet operating mechanism
High reliability and maintenance-free for smart grid equipment
Comply with national standard GB1984 and International Electrotechnical Commission standard IEC62271-100
Can cooperate with intelligent controller to form intelligent circuit breakers, breakers, reclosers and other intelligent switches
