Description for Vertical Line Post Insulator:
The rod core of composite insulator has high tensile strength and good aging resistance., still elastic at 70 degrees Celsius and long term operational at 20 degrees Celsius.The surface has hydrophobicity, and it is not easy for the water to form a conductive path in the granular form on the surface. In addition, the composed insulator umbrella disc has small diameter, large climbing distance, high surface resistance and small leakage current, so it has high pollution lightning pressure.

The composite insulators are made of special steel fittings. The metal fittings end adopts the labyrinth design principle, with multi-layer protection and good sealing performance, which solves the most critical problem of insulators ---- interface electrical breakdown. The connection between the fixture and the mandrel adopts the most advanced computer controlled coaxial constant pressure crimping process in the world, and is equipped with automatic acoustic emission flaw detection system to ensure the reliability and stability of the connection between the fixture and the mandrel. The mandrel adopts ERC high temperature acid resistant mandrel and the interface between mandrel and silicone rubber is coated with special coupling agent. Umbrella cover adopts one-time integral molding process under high temperature and high pressure, and two-stage vulcanization process under computer monitoring, which prolongs the service life of the product.
