Description:
Composite pin insulator is applicable for high-voltage line facilities. The insulator has good water-repellent, anti-aging and anti-leakage properties. And it is also featured by high resistance to bending and high mechanical strength. It is easy for installation and its installation dimensions of top and bottom parts are the same with those of corresponding porcelain pin type so that they are interchangeable.
Features:
1. Excellent electric corrosion-proof property.
2. High mechanical intension.
3. Light weight and easy installation.
