GW13 Series Disconnector:
GW13 type main transformer neutral is alternating current 50Hz outdoor electric equipment.
In the event of the no bearing, it used as the transformer neutral point to connect the ground.
It also can be used as the ground connecting equipment composed with the adjustable
discharge gap, gap support isolated pillar and current mutual inductor.
