SW2-63 High voltage low oil circuit breakerDetailed product description：

The SW2 series high-voltage low oil circuit breaker is a three-phase AC 50Hz outdoor high-voltage power equipment, mainly used for control and protection of transmission lines, and can also be used as a contact circuit breaker. This series of circuit breakers is based on a 63kV arc extinguishing unit, using a double tube structure arc extinguishing chamber and a longitudinal and transverse arc extinguishing principle. Form a single or multiple break block structure according to different voltage levels. SW2-63 type single column single fracture surface per phase. SW2-110 type single column double fracture surface for each phase. SW2-220 type double column with four fracture surfaces per phase. The SW2 series low oil circuit breaker is developed based on SW2-60 and SW6-220 through a series of significant improvements. This product has the characteristics of strong series, high breaking current, simple structure, reliable action, and easy installation and debugging
