Supply zinc oxide surge arrester HY5WS-17-50 composite metal oxide
surge arrester HY5WS series
Small size, light weight, collision resistant, flexible
installation .
Special structure, no gap, good sealing, corrosion resistance.
Pollution resistance, stable performance , best of creepage
distance , aunti-fouling .
The switch room consists of various functional circuits(including
grounding switches and load switches) sealed in the metal casing
and busbar between them. The shell is made of 3-inch cold rolled
steel plate(or unembroidered steel plate) welded. Each functional
loop includes a load switch and a grounding switch. The load switch
is composed of a vertical moving contact system and a static
contact at the lower end. When the switch is closed, the contact
moves downward and the load switch is connected. The ground switch
is composed of a moving contact knife and a static contact knife.
The upper and rear of the switch room are provided with 4
rectangular assemblers, and the front of the loop cabinet is
provided with observation Windows. An explosion-proof device is
installed at the rear of the ring cabinet.
