The composite line post insulator is composed of insulating mandrel, rod umbrella sleeve and connecting joint is composed of three parts at both ends. Insulator mandrel is referred to as epoxy resin glass fiber drawing rod, it is the skeleton of the composite insulators, plays a supporting the umbrella, insulation, at two ends of the connecting pipe and bear the multiple roles of mechanical load, have very high tensile strength, generally up to 600 MPa is 2 times, 8 times of Pu Tonghua, 5 ~ ceramic material has good dielectric properties and resistance to chemical corrosion, and has a good anti bending fatigue UE and creep resistance and impact resistance. Silicon rubber umbrella cover main rod protection and shielding rain and snow, increase the creepage distance and product external insulation effect, silicon polymer rubbercontact scanningheadquarters as matrix, supplemented by flame retardant, anti aging agent, and has good hydrophobicity and migration after curing at high temperature and high pressure coupling agents and fillers, resistance to corrosive good, aging resistance and electrical insulation properties. High pollution flashover voltage and anti breaking performance, uniform voltage distribution, compared to the porcelain flashover voltage under the same conditions is 2 times more.
