Product Description

Product Introduction: Long Rod Suspension Type Composite Insulator

The Long Rod Suspension Type Composite Insulator is a high-performance insulating component widely used in overhead transmission lines and substations. Compared with traditional porcelain insulators, composite insulators offer better anti-pollution ability, lighter weight, and longer service life, making them essential in modern power systems.

Structure and Materials

This insulator is mainly composed of:

• Core Rod: Made from high-strength epoxy fiberglass, ensuring excellent tensile strength and corrosion resistance.

• Shed Housing: Molded from premium silicone rubber with superb hydrophobic and anti-pollution properties.

• End Fittings: Hot-dip galvanized steel, tightly crimped with the core for maximum structural integrity.

Technical Parameters

• Rated Voltage: 35kV / 66kV / 110kV (customizable)

• Mechanical Tensile Strength: 70kN / 100kN / 160kN

• Creepage Distance: ≥500mm (varies with voltage level)

• Pollution Class: Class IV (optional RTV coating)

• Operating Temperature: -40ºC~+55ºC

• Anti-Burst Safety: Superior to porcelain; no shattering upon breakdown

Performance Features

1. High Insulation Strength: Silicone sheds enhance creepage distance and reduce flashover risk.

2. Strong Anti-Pollution: Excellent hydrophobicity with surface self-cleaning effect.

3. Lightweight: 1/3~1/5 the weight of porcelain insulators, ideal for difficult terrains.

4. Easy Installation: Manual handling possible without heavy lifting equipment.

5. Resistant to Wind and Shock: Flexible design mitigates mechanical stress.

6. Long Lifespan: Silicone rubber is UV and aging-resistant, ensuring 25+ years of service.

Application Fields

This product is suitable for:

• Urban and rural overhead high-voltage transmission lines

• Mountain or heavily polluted power zones

• Renewable energy lines (wind, solar)

• Industrial areas and railway power systems

Customization Options

We offer flexible customization for different voltage classes, tensile loads, shed shapes, colors, and lengths. Enhanced anti-pollution coatings and OEM/ODM services are also available to meet various project demands worldwide.
