Description:
GW38-40.5~252/630~4000 Type Three post Horizontal Double break disconnector
Double break is good for reducing the distance and station arranging, especially for indoor station.
Because of electric rod's self-rotation and switching structure and having self-locking function, it has strong property of motor performance resistance. Meanwhile, it can resist motor, wind pressure, earthquake and other outside power.
Contact and finger's on and off way is sliding rotation,
