High voltage composite insulator end fittings are essential components used to connect insulators to conductors, towers, or electrical equipment. These fittings ensure mechanical strength, alignment, and electrical performance in power transmission systems.
WishPower manufactures a wide range of lightweight end fittings designed for composite insulators, using materials like hot-dip galvanized steel, stainless steel, and aluminum alloy. The fittings are engineered for high tensile strength, corrosion resistance, and easy installation.
We offer customization options for different connection types, including ball & socket, clevis, tongue, flange, and more.
