Product Description

Introduction to 20kV Pin-Type Composite Insulator

The 20kV pin-type composite insulator is a key component widely used in medium voltage transmission and distribution systems. Compared with traditional porcelain insulators, composite insulators are lighter in weight, better in insulation performance, and more suitable for long-term outdoor use under harsh environmental conditions.

This product is made of advanced composite materials and offers excellent pollution resistance and high mechanical strength. It is ideal for substations, distribution lines, and urban/rural electrical grids.

Structure and Materials

  • Core Rod: Made of high-strength epoxy fiberglass for superior tensile and bending performance.

  • Housing: Made of top-grade silicone rubber, with excellent weather resistance and hydrophobicity.

  • Metal End Fittings: Hot-dip galvanized steel or aluminum alloy for corrosion resistance and firm mechanical connection.
