33KV Glassfiber Epoxy Core Rod Polymer String Pin Tension Insulator
Normal service conditions:
1. The ambient temperature: -40°C ~+40°C
2. The altitude above sea level :not exceed 1000-2000m (the altiplano area should be indicated when order)
3. Earthquake intensity: not higher than 7 degrees;
4. Maximum wind velocity :less than 35m/s.
5. The filthy area should be given clear indication.
The Pin Type Polymer Insulator are made of glassfiber epoxy core rod, silicone rubber shed and metal fittings.
The silicon rubber sheds adopt the whole packing pressure technique, and then to solve the key problem – interface electric spark puncture, which would affect the reliability of composite insulator.
Connection of the glassfiber rod and metal fittings, adopts the pressure welding technique of the international advanced level, and have the full automatic sound wave detection of defects system, high intension, beautiful outline, small volume, light weight, and the metal fitting with galvanization can prevent corrosion, and more and more polymer insulators replace the porcelain insulators.
This product is reliable structure, can’t damage the FRP rod, and take full advantage of the mechanical strength.
