Light gray color TR-208 Transmission line Soild-Core Station post
insulator
Descriptions:
1. Our insulators have externally attached caps and bases. A highly
engineered cementing system transfers the load uniformly from the
hardware into the porcelain body.
2. Each insulator body is made from the highest quality clay raw
materials that have been processed to be fully vitrified porcelain.
The body is glazed to add strength to improve surface appearance,
and enhance clean-ability.
3. Either chocolate brown or Munsell gray glaze is available. caps
and flanges are ferrous, hot dip galvanized. thread holes are
proper tapped.

Applications:
The insulator can be used as insulation parts ,which provide
mechanical support . it can also be used as electrical canbinet
insulation parts.
Design features:
1. Porcelain part of this series post insulator is solid
construction with cylinder sand on cementing part.The porcelain
body was bond with metal part by cement.Brown glaze color on
porcelain surface which also can be white or gray as per customer’s
requirement.
2. The material for metal part adopt nodular cast iron with high
mechanical strength conducting hot galvanizing and better resistant
to rust.
