Pin Type Composite Polymer Insulator for High Voltage Overhead Transmission Line
 
 
Description:
 
The Polymer Insulator are made of glassfiber epoxy core rod, silicone rubber shed and metal fittings.
 
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.
 
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.
 
This product is reliable structure, can’t damage the core rod, and take full advantage of the mechanical strength.
 
 
 
Product Structure:
 

1. The design of shed adopted unique aerodynamice principle.
2. The shed and sheath adopted the whole moulding technique.
3. Sheath thicknew accord with the IEC international standard.
4. Adopt ERC high-temperature fortified acid-proof model core rod.
5. The end seal adopted tie high temperature sulfuration high pressure seal technique, to achieve to the aim of three-protecttion, to ensure the end seal of metal fitting is reliable performance.
6. Adopt international advanced aompaction joint technique for metal fitting connection.
7. Excellent original material manifacture of products. Whichthehydrophobicity can reach to HC1 level.
8. The unique notch design of metal fitting& same thickness of notch, prevent top end discharge.
9. The galvanizing coat of metal fitting adopt the technique of rare earth aluminum hot galvanizing, to avoid the zine continue dropout during compaction joint.
