Abstract

The invention discloses a high temperature resistant insulation composite insulator which comprises an insulation core rod, an umbrella skirt and a metal fitting. The umbrella skirt coats the insulation core rod. The metal fitting coats two ends of the insulation core rod and is connected to two ends of the umbrella skirt. The umbrella skirt is made from a rubber material. The high temperature resistant insulation composite insulator is resistant to high temperature, has good electrical insulation property, high mechanical strength, corrosion resistance and radiation resistance, is simple and convenient to operate and has short processing time.

Description

technical field [0001] The invention relates to the technical field of composite insulators, in particular to a high temperature resistant insulating composite insulator. Background technique [0002] Fluorine rubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. Fluorine rubber has excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance, and has good mechanical properties, electrical insulation properties and radiation resistance. [0003] Fluorosilicone rubber has excellent heat resistance, cold resistance, oil resistance, chemical resistance, electrical insulation, high mechanical properties, etc. [0004] Nitrile silicone rubber is a type of silicone rubber with nitrile alkyl groups introduced into the side chain. The introduction of polar cyano groups improves the oil resistance and solvent resistance of silicone rubber. [0005] Prec...
