35kV Rod Suspension Composite Insulator for Overhead Power Lines

Product Overview

A 35kV rod suspension composite insulator is an essential insulating and mechanical support component used in medium-voltage and high-voltage overhead power systems. It is designed to suspend conductors, provide electrical insulation and withstand mechanical loads in outdoor environments. Wishpower 35kV rod suspension composite insulator is manufactured with a silicone rubber housing, fiberglass core rod and galvanized metal end fittings, offering excellent anti-pollution performance, lightweight installation and long-term reliability for 35kV overhead lines.

Wishpower 35kV rod suspension composite insulator is designed for 35kV power distribution and transmission applications. It is widely used in overhead lines, distribution networks, rural power grids, urban power systems and substation line entrances. Compared with traditional porcelain insulators, composite insulators provide better impact resistance, lower weight and improved performance in polluted environments.

Key advantages of Wishpower composite insulators include:

• High-temperature vulcanized silicone rubber housing with excellent hydrophobicity;

• High-strength fiberglass core rod for reliable mechanical load capacity;

• Hot-dip galvanized end fittings for strong connection and corrosion resistance;

• Lightweight design for easier transportation and installation;

• Excellent performance in polluted, humid, coastal, sandy and mountainous areas;

• Reduced breakage risk and lower maintenance cost compared with porcelain insulators.

Core Features

1. Excellent Electrical Insulation Performance
   The 35kV rod suspension composite insulator provides reliable insulation performance for overhead power lines and helps reduce flashover risks during operation.

2. Strong Anti-Pollution Capability
   The silicone rubber housing offers excellent hydrophobicity, helping reduce leakage current and improve service reliability in polluted or humid environments.

3. High Mechanical Strength
   The fiberglass core rod provides strong tensile strength, making the insulator suitable for conductor suspension and mechanical load-bearing applications.

4. Lightweight and Easy to Install
   Compared with porcelain insulators, composite insulators are lighter and easier to transport, handle and install.

5. Good Aging and Weather Resistance
   The product is suitable for long-term outdoor operation and offers resistance to UV, ozone, temperature changes and environmental aging.

6. Low Maintenance Cost
   The composite structure is not easy to break, helping reduce inspection frequency, replacement cost and line maintenance workload.

Product Structure

The 35kV rod suspension composite insulator is generally composed of the following parts:

• Silicone Rubber Housing: Provides external insulation, weather resistance and anti-pollution performance;

• Fiberglass Core Rod: Works as the main mechanical load-bearing component;

• Metal End Fittings: Used for connection with towers, conductors and line fittings;

• Sealing System: Prevents moisture and contaminants from entering the core and fitting interface;

• Interface Bonding Layer: Ensures structural stability between housing, core rod and end fittings.
