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:

 

We offer 1 years up to 2 years quality guarantee for our product.

The insulator finish are smooth and shinning, it has very good self-cleaning performance and easy for maintenance.

OEM design are available.
