Description

ZW20-12 series outdoor high-voltage vacuum circuit breaker is a kind of three-phase outdoor high-voltage switchgear of rated voltage 12kV and AC 50Hz.
Its population structure is three-phase together box type. Three-phase vacuum arc-extinguish chamber palaces in a metal cabinet, using the SMC insulating material to insulate inter-phase and phase to earth, which is reliable in performance and high in insulating intensity.

ZW20-12G is combined with ZW20-12 circuit breaker and isolating sword, called combination circuit breaker and used as a section switch.
