1.5kV Rigid Suspension Composite Insulator for Urban Rail Systems

Product Overview

Wishpower 1.5kV rigid suspension composite insulator is specially designed for rigid overhead contact systems in urban rail transit. It is used for insulation, support and mechanical connection in 1.5kV DC traction power networks. Compared with traditional porcelain insulators, composite insulators are lighter, easier to install and more resistant to pollution flashover and mechanical impact.

Main advantages of Wishpower composite insulators include:

• High insulation performance: Silicone rubber housing provides excellent hydrophobicity and helps reduce pollution flashover risks.

• Lightweight design: Lower weight makes installation easier in tunnels, elevated lines and limited-space structures.

• Stable mechanical strength: High-strength epoxy fiberglass rod provides reliable tensile, bending and vibration resistance.

• Excellent weather resistance: Suitable for humid, dusty, salty and condensation-prone operating environments.

• Low maintenance cost: Composite material is less fragile than porcelain and helps reduce inspection and replacement frequency.

• Flexible customization: Dimensions, fittings, creepage distance and mechanical load can be customized according to project requirements.

Core Features

1. Designed for 1.5kV DC traction systems
   The product is suitable for urban rail contact systems, including metro, light rail and tram traction power networks.

2. Silicone rubber housing with strong pollution resistance
   The silicone rubber material offers excellent hydrophobicity and hydrophobicity transfer, helping maintain insulation performance in polluted or humid conditions.

3. High-strength fiberglass core for mechanical reliability
   The epoxy fiberglass core provides stable mechanical load capacity, making it suitable for long-term stress and vibration in rigid suspension systems.

4. Suitable for tunnels and underground spaces
   The compact and lightweight structure is ideal for metro tunnels, underground sections, depots and areas with limited installation space.

5. Resistant to aging, UV and corrosion
   The external insulation and metal fittings are designed for long-term operation in indoor, semi-outdoor and humid environments.

6. Customized production available
   Wishpower can manufacture products according to customer drawings, installation methods, fitting dimensions, rated voltage and mechanical load requirements.

Product Structure

The 1.5kV rigid suspension composite insulator usually consists of the following components:

• Epoxy fiberglass core rod
  The main load-bearing part that provides tensile, bending and mechanical support strength.

• High-temperature vulcanized silicone rubber housing
  The external insulation layer that provides creepage distance, pollution resistance and weather protection.

• Metal end fittings
  Usually made of hot-dip galvanized steel, stainless steel or aluminum alloy for connection with catenary brackets, suspension devices or fixing structures.

• End sealing system
  Prevents moisture, dust and contaminants from entering the interface between the core and fittings.

• Integrated molded structure
  Ensures tight bonding among the core rod, housing and fittings, improving mechanical and electrical stability.
