Structure & Material Description

This railway insulator typically consists of three main parts:

  • Core Rod: Made from epoxy-coated fiberglass, offering excellent tensile and dielectric strength.

  • Sheds (Umbrella Skirts): Molded from premium silicone rubber with superior hydrophobicity and UV resistance.

  • Metal Fittings: Hot-dip galvanized steel or aluminum alloy, corrosion-resistant and mechanically reliable.
