Product Description

69kV Rod-Type Suspension Composite Insulator

1.Product Introduction

The 69kV rod-type suspension composite insulator is a high-performance insulation product widely used in high-voltage power transmission lines and substations. It offers excellent electrical insulation and mechanical strength. Designed with advanced composite materials and a rod-style suspension structure, this insulator is ideal for long-term outdoor applications in harsh environments.

2.Structure and Materials

This composite insulator consists of three main parts:

  • Fiberglass-reinforced epoxy resin core rod: Delivers high tensile and bending strength.

  • Silicone rubber housing: Features superior hydrophobicity, aging resistance, and pollution resistance.

  • Metal end fittings (hot-dip galvanized steel or aluminum alloy): Ensure firm mechanical and electrical connections.
    The entire insulator is produced using a unified injection molding process, guaranteeing tight sealing and defect-free construction.
