Glazed Lightning Arrester Insulator 66kV surge arrester





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.
