Multifunctional Silicon rubber insulator

Silicon rubber insulator 1.We are able to offer 33kV, 11kV, 132kV silicon rubber insulators 2 the number of grading ring

It is suitable for overhead line electrical insulation of suspention or tension. it has a good mechanical properties.

The composite insulator is composed by three components of insulation core rod; silicon rubber shed cover and the connecting hardware at the both ends. The insulation core rod is the abbreviation name of epoxy resin fiberglass pultruded rods, which is the frame of the polymer insulator with multifunction of supporting the shed cover, internal insulation, connecting hardware at both ends and bearing mechanical load ect. The insulation core rod has high tensile strength of over 600MPa, which is twice of common steel and 5 to 8 times of porcelain. Also the core rod has good performances in dielectric property, chemical attack resistance, bending fatigue resistance, creep resistance and impact resistance. The silicon rubber shed cover is mainly functioned by protecting core rod, shielding rain and snow, increasing the creepage distance and providing external insulation for the product etc. It is made with high polymer silicon rubber as the matrix and vulcanized under high temperature and high pressure with the assistance of fillers such as fire retardant, aging resistant and coupling anent etc. The shed cover has good performances in hydrophobicity , migration, corrosion resistance , aging resistance and electrical insulation etc. and can provide extremely high pollution flashover voltage and smashing resistance performance. The voltage is evenly distributed and the flashover voltage is twice of porcelain compared with porcelain under the same conditions.
