The high voltage polymer composite insulator is an essential component used in high-voltage transmission and distribution systems. It provides reliable insulation and mechanical support for conductors. Compared to traditional porcelain or glass insulators, polymer insulators offer significant advantages such as lighter weight, superior insulation properties, and high resistance to pollution and environmental stress.
This insulator mainly consists of three parts: a fiberglass rod core, a silicone rubber housing, and metal end fittings.
Core Rod: Made of epoxy resin reinforced fiberglass, it offers excellent mechanical tensile strength.
Housing: High-quality silicone rubber with strong hydrophobicity and aging resistance.
End Fittings: Hot-dip galvanized steel or aluminum alloy ensures secure mechanical connection and conductivity.

Excellent Insulation: Silicone rubber offers high hydrophobicity and anti-tracking resistance.
Lightweight: Only one-third the weight of porcelain, reduces installation cost.
Anti-Corrosion and Earthquake Resistant: Stable in extreme environments like salt, snow, and high altitude.
High Mechanical Strength: Fiberglass core delivers superior tensile and bending strength.
Long Service Life: More than 30 years of lifespan with low maintenance.
These composite insulators are widely used in high-voltage overhead lines, railway power systems, wind and solar power access, and harsh outdoor environments such as coastal or industrial areas. Ideal for both urban and rural electric networks.
