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
