Customized Polymer Station Post Insulators For Electrical Switches

3010006H,3010008H,3010010H​ porcelain bus support / station post insulator are mainly for US market .

the insulator mainly used for fuse switches .

The product are with cast iron metal caps on both end . ​

both end of surface must be parallel very well , and the counterpart outstanding bolt on both end must be in

line , and each pieces of bolt must be vertical against metal cap surfact , otherwise the support insulator can't be used . in one word , there are very high requirement on

insulator dimensional control .

on the other side , the insulator must provide very high mechanical strength .

because the insulator are with long bolt fixed on both end , so the bolt will burden high strength mechanical

load , we have to choose special high strength steel as bolt material.

and we use C-130 aluminum porcelain as porcelain parts material  .

Applications:

Suitable for electrical switch 23KV . The insulator can be used as insulation parts ,which provide mechanical support . it can also be used as electrical canbinet insulation parts.

Competitive Advantage:

very strictly dimensional control on the insulators , and excellent mechanical strength .

​price are more competitive than the same product produced in USA.

we offer 3 years quality guarantee .

we can design similar type of insulators based on customer's requirement
