Brief introduction:
ZW****0.5 type VCB use the latest design idea in the world, material for pole of vacuum interrupter is resin with APG embeded

insluation which is leading in the world. That it was mainly used in outdoor power system of *5kV rated voltage, AC *0Hz 3ph to

connect and dis-connect load current, overload current and short circuit current. Especially applicable for the station where frequently

operation is required.
