66kV Long Rod Suspension Composite Insulator for Overhead Lines

Product Overview

The 66kV long rod suspension composite insulator is an essential insulation and mechanical support component for high-voltage overhead transmission lines. It is designed to withstand conductor tension, provide reliable electrical insulation and ensure stable line operation. Wishpower 66kV long rod suspension composite insulators are manufactured with a high-strength fiberglass core, silicone rubber housing and metal end fittings, offering lightweight construction, excellent pollution resistance, strong mechanical performance and easy installation.

Wishpower 66kV long rod suspension composite insulator is designed for 66kV transmission lines, overhead lines and outdoor high-voltage power systems. Compared with traditional porcelain and glass insulators, composite insulators provide better advantages in weight reduction, anti-pollution performance, transportation, installation and long-term maintenance.

Key advantages include:

• Lightweight design: Easier to transport, install and handle on site.

• Excellent pollution resistance: Silicone rubber housing provides strong hydrophobicity and hydrophobicity transfer.

• High mechanical strength: Fiberglass core offers reliable tensile strength for overhead line applications.

• Strong weather resistance: Suitable for UV exposure, rain, salt fog, dust and outdoor aging conditions.

• Low maintenance cost: Less risk of breakage and reduced inspection or replacement frequency.

3. Product Structure

The 66kV long rod suspension composite insulator generally consists of the following components:

• Fiberglass core rod
  Provides the main mechanical strength and tensile load capacity.

• Silicone rubber housing
  Works as the external insulation layer with excellent hydrophobicity and weather resistance.

• Composite shed profile
  Increases creepage distance and improves insulation performance in polluted environments.

• Metal end fittings
  Used for connection with conductors, towers, crossarms and line hardware. Common types include ball socket, tongue, clevis and eye fittings.

• End sealing system
  Prevents moisture from entering the core and fitting interface, improving long-term reliability.
