Product Description

Product description
The ZW20 putdoor load break switch, with SF6 gas insulation, rated voltage can be 12kv, 24kv or 36kv. It can realize remote digital control with a control box and PT. It is mainly used for breaking and closing current, overloading current, and short-circuit current protection. This LBS adopts mature case type sealing structure for SF6 gas insulation. Therefore, it has excellent sealing performance not to be much less effected by external environment. In addition, this switch has the spring mechanism with chain main transmission and a multi-stage tripping system, which makes this switch qualtiy reliable.
