We can supply all kinds of insulation poles for HV switches, surge arresters, etc.
There are five types:
1.Insulation poles with thread.
2.Insulation poles crimped with metal fittings;
3.Insulation poles with silicone rubber housing and metal fittings.
4.Insulation poles with wear-resistant material housing and metal fittings.
5.Insulation poles with UV resistant protection layers.
We can design and manufacture different kinds of insulation poles according to customers’ requirements.
