Overhead Transmission Lines Composite Suspension Insulators For High Voltage 25 Kv
product
The features of Overhead Transmission Lines Composite Suspension Insulators For High Voltage 25 Kv
1.The Composite Insulator are made of glassfiber epoxy core rod, silicone rubber shed and metal fittings.
2.The silicon rubber shed 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.
3.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 of
galvanization can corrosion prevention and exchange used with porcelain insulator.
4.This product is reliable structure, can’t damage the core rod, and take full advantage of the mechanical strength.
