It is for high voltage releasing electricity or reduce voltage, extension discharge stem structure,hook head or line pin head.

The extension discharging stem is for high voltage releasing electricity or reduce voltage,it is made of extension struction,could be extended based on original rod.Gegerally,it is used to release electricity after outdoor high voltage testing in samples or devices,especially for DC lasting testing,the rest element should be released to the earth ground after testing.. That is needed to insure safety of the workers.

Specifications:

1)The rods:made of polyester/glass fiber,,length 1-5m or other, 3-5parts.

2)Copper wire section:25mm2 4length --6m length or other.

3)Earth clamp is aluminum/copper.

4)Suited voltage grade;10KV;35KV;66KV;110KV;220KV;500KV

We may design and manufacture based on your requirement.
