Polymer Suspension Insulator

Polymer suspension insulators are high-tension insulators with a capacity of over 70 kN. They consist of three main parts: hydrophobic silicone rubber sheds, a high-strength epoxy resin glass fiber core rod, and hot-dip galvanized end fittings. They are also known as silicone rubber insulators.

Featuring light weight, a long creepage distance, corrosion resistance, and excellent mechanical and electrical properties, polymer suspension insulators are highly suitable for heavy pollution areas.
