66kv Polymer Pin Post Insulator

Composite pin insulators for high-voltage transmission lines have high bending resistance, torsional strength, impact resistance, seismic resistance, and superior explosion-proof performance. The internal insulation is reliable, lightweight, and easy to install, making it an ideal replacement product for traditional pin type porcelain insulators.

The insulator is made of special steel fittings, and the end of the fittings adopts a labyrinth design principle, with multi-layer protection and good sealing performance, solving the most critical problem of the insulator - interface electrical breakdown. The connection between the hardware and the core rod adopts the most advanced computer-controlled coaxial constant pressure crimping process in the world, and is equipped with a fully automatic acoustic emission flaw detection system, ensuring the reliability and stability of the connection between the hardware and the core rod. The core rod adopts ERC high-temperature acid resistant rod, and the interface between the core rod and silicone rubber is coated with special coupling agent. The umbrella cover adopts a one-time overall molding process under high temperature and pressure, combined with a two-stage vulcanization process monitored by a computer, to extend the service life of the product.
