Horizontal Line Post Insulator

The horizontal line post insulator is used in overhead transmission lines and is typically installed on the cross arm of a pole or tower. It is designed to withstand horizontal lateral tension and prevent conductor vibration and sagging, ensuring the stability of the power system.

The horizontal line post insulator consists of hot-dip galvanized end fittings, a glass fiber core rod, and a hydrophobic silicone rubber shed. It is lightweight and easy to install and offers excellent mechanical strength, corrosion resistance, and electrical insulation performance.
