Product Description

Introduction to 25kV Polymer Dead End Insulators

25kV Polymer Dead End Insulators are specially designed for the terminal support of overhead power lines in distribution networks. With superior electrical and mechanical properties, they are the ideal replacement for traditional ceramic insulators in modern power systems.

Structure and Materials

This product consists of three main components:

• Core Rod: Made of high-strength epoxy fiberglass for excellent tensile resistance.

• Silicone Rubber Sheds: Provide strong hydrophobicity, UV resistance, and anti-aging performance for outdoor durability.

• Metal End Fittings: Typically hot-dip galvanized steel or aluminum alloy, ensuring secure mechanical connections.
