Horizontal post insulators for transmission lines are vital components in high-voltage systems, used to provide mechanical support and electrical insulation in substations, transmission towers, and distribution lines. Compared to traditional porcelain or glass insulators, composite horizontal post insulators offer superior pollution resistance, reduced weight, and longer service life, making them ideal for modern power grid upgrades.
This insulator mainly consists of three parts: a fiberglass reinforced epoxy resin (FRP) rod as the core, high-performance silicone rubber sheds, and metal end fittings. The FRP core delivers high tensile and bending strength, while the silicone rubber sheath offers excellent hydrophobicity, anti-aging properties, and electrical tracking resistance. Metal end fittings ensure secure installation and electrical continuity.
