Product Description

Composite Guy Strain Insulator Overview

Composite guy strain insulators are advanced high-strength insulating devices used to support and insulate guy wires in overhead power and communication lines. Compared with traditional porcelain or glass insulators, composite strain insulators are lighter in weight, more resistant to pollution, and offer excellent mechanical performance. They are ideal for urban distribution networks, telecommunication towers, and electrified railways.

Structure and Material Description

The composite guy strain insulator mainly consists of:

1. Core Rod: Made from high-strength epoxy fiberglass, it provides superior tensile strength and durability.

2. Sheath (Weather Sheds): Molded from high-quality silicone rubber, offering excellent hydrophobicity, aging resistance, and anti-pollution properties.

3. Metal End Fittings: Hot-dip galvanized steel or aluminum alloy fittings, crimped securely to the core rod for optimal mechanical performance and sealing.

This well-designed structure ensures long service life and reliable insulation even in harsh environmental conditions.

Technical Specifications

• Rated Voltage: 10kV ~ 35kV (customizable)

• Tensile Strength: 70kN, 100kN, etc.

• Insulation Length: 300mm - 1000mm (adjustable)

• Material: Silicone rubber & epoxy fiberglass

• Operating Temperature: -40ºC to +85ºC

• Pollution Class: Level IV or above

• Expected Lifespan: ≥25 years

Performance Features

1. High Mechanical Strength: Excellent tensile strength to withstand heavy mechanical loads in guying applications.

2. Excellent Weather Resistance: Silicone rubber sheds perform well under pollution, moisture, and UV exposure.

3. Lightweight & Easy Installation: Easier transportation and installation compared to ceramic alternatives.

4. Safe & Durable: Non-brittle material eliminates explosion risk and resists vibration and shock.

5. Low Maintenance: Strong hydrophobicity reduces cleaning and maintenance needs.

Application Scope

Composite guy strain insulators are widely used in overhead distribution lines, telecommunications guying systems, transmission towers, railway electrification structures, and utility poles. They perform well in high-altitude, coastal, and heavily polluted environments.
