Feature

1. The polymer pin type insulators is made of special steel.

2. The end of the fitting adopts the labyrinth design, multi-layer protection and good sealing performance.

3. It solves the most critical problem of the insulator----interface electrical breakdown.

4. The connection between metal fitting and rod adopts the most advanced technology in the world which is computer-controlled coaxial constant pressure crimping technology.

5. It is equipped with a fully automatic acoustic emission flaw detection system to ensure the reliability and stability of the connection between metal fitting and rod.

6. The core rod adopts ERC high temperature acid resistant rod.

7. Core rod and silicone rubber interface are coated with special coupling agent.

8. The umbrella cover adopts one-time integral molding process under high temperature and high pressure, and with two-stage vulcanization process under computer monitoring.
