Earthing System Silicone Rubber Surge Arrester

Zinc oxide compound sheath non-clearance surge arrester is used to protect the corresponding voltage-grade alternating current (AC) electric apparatus from the excess voltage.

Technology advantages

With perfect prescription ,the silicon rubber shed booster is smooth and compact, provides perfect hydrophobic performance, good resistance to aging, tracking and erosion.

The adoption of the high-strength acid-resistant FRP rod ensures the reliability of composite insulator.

The arcing corona ring well distributes the electric field along the insulator’s axe to prevent corona phenomenon and secure the insulator from heavy damage in end fitting in case of flashover.

The end fitting and FRP rod are connected with imported end-fitting crimping equipment from Finland and the acoustic emission detector from the US which ensures the mechanical performance of the product.

The unique end fitting sealing structure improves product sealing reliability.

The strict inspection measures ensure the perfect quality of every product.

Product advantages

Its protective property is excellent and the antipollution outstanding as well as its volume is small and the weight light. Because the sheath is made from organic material such as silicon rubber and EP (epoxide) it can avoid some kind of serious explosive accident, for example the one caused by ceramic arrestor.
