As insulating and supporting conductor in HV transmission & distribution line, post insulators are divided into line post porcelain insulator, cross arm porcelain insulator and long rod suspension insulator, etc.
Applications:
The insulator mainly used for fuse switches , or bus support insulations. The product are with cast iron metal inserts on both end .
Features:
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.
Competitive Advantages:
1. very strictly dimensional control on the insulators , and excellent mechanical strength .
2. price are more competitive than the same product produced in USA.
3. we offer 3 years quality guarantee .
4. we can design similar type of insulators based on customer's requirement
