The 11kV Suspension Composite Long Rod Insulator is a reliable high-voltage insulation solution widely used in medium-voltage transmission lines and power distribution systems. Manufactured with composite materials and designed with a suspension structure, this insulator offers excellent dielectric properties and high mechanical strength. It ensures safe operation of the power grid, even in challenging environmental conditions.
The insulator consists of the following main components:
Core Rod: High-strength epoxy resin fiberglass rod, offering outstanding tensile strength.
Housing and Sheds: Made from high-grade silicone rubber, providing excellent hydrophobicity, UV resistance, and aging resistance.
Metal Fittings: Hot-dip galvanized steel end fittings ensure secure mechanical connections and electrical conductivity, compatible with various tower and pole structures.
