The composite insulator is made up of the insulated core bar, the silicon rod rubber umbrella and the two ends.
Insulation core rod is short for epoxy resin glass fiber led pull rod, it is the skeleton of composite insulator, plays an umbrella cover, inner insulation and hardware on both ends of the connection, and withstand the mechanical load multiple role, has the very high tensile strength, generally can reach more than 600 mpa, 2 times that of ordinary steel, 5 ~ 8 times of porcelain material, and has good dielectric properties and chemical corrosion resistance, and good resistance to bending fatigue, creep resistance and impact resistance. Silicon rubber umbrella cover main plays a core rod, block rain and snow, increase the creepage distance and the effect of external insulation products, is a polymer of silicone rubber as the matrix, complementary with flame retardant, anti-aging agent, coupling agent, such as packing by high temperature and pressure curing, has the good hydrophobic and mobility, as well as good corrosion resistance, ageing resistance, electric insulation performance, etc. And it has very high fouling and crushing performance, the voltage distribution is even, and compared with porcelain, the voltage is more than twice that of porcelain.
