The 33kV composite insulated arm insulator is designed for use in power distribution systems, particularly in arm-type structures of switchgear and substations. Manufactured with advanced composite materials, it delivers excellent electrical insulation and mechanical strength, making it a reliable replacement for traditional ceramic insulators.
This insulator is composed of three main parts: fiberglass core rod, silicone rubber shed, and end fittings. The core rod is made of high-strength epoxy fiberglass, offering outstanding tensile and bending strength. The silicone rubber sheath ensures hydrophobicity and anti-pollution performance. End fittings are made from hot-dip galvanized steel or aluminum alloy, ensuring secure installation and corrosion resistance.
