The WishPower 7.5kV Post Composite Insulator is a high-performance electrical insulator designed for medium-voltage applications. Engineered with advanced composite materials, it is an ideal solution for enhancing safety and efficiency in power distribution networks and substations.
This post-type composite insulator is commonly used in 7.5kV or below power distribution systems, substations, switchgear, and industrial power infrastructure. It provides excellent insulation, superior mechanical performance, and outstanding resistance to pollution and weather conditions.
The core of the insulator is made of epoxy glass fiber rod offering high tensile and bending strength. The external housing is molded with premium silicone rubber, which is hydrophobic, pollution-resistant, and UV-stable. End fittings are made of hot-dip galvanized steel, ensuring secure mechanical connections and corrosion resistance.
