Composite Polymer Insulator ECR Fiberglass Rod

Introduction of composite insulator structure
The Composite insulator is also called synthetic insulator. Its main structure is composed of three parts: gold skirt, epoxy glass fiber (FRP) mandrel and end gold. Among them, the skirt is made of high temperature
Made of vulcanized silicone rubber, the FRP mandrel is a glass fiber reinforced plastic composite material with glass fiber as reinforcement and epoxy resin as the rest.
Cast steel or carbon structural steel.
This structure of the composite insulator separates the mechanical strength from the external insulation performance. The mandrel and the full skirt are subjected to mechanical and electrical loads respectively, and the most comprehensive combination of the full skirt material is resistant to wear and tear.
It has the advantages of superior gas and aging properties and good tensile mechanical properties of the mandrel material. As a part of the insulator structure, the fittings mainly play the role of transmitting mechanical stress and connecting and fixing.
