10kV Composite Long Rod Insulator

Product Overview

The 10kV composite long rod insulator is designed to suspend conductors, withstand mechanical loads and provide reliable electrical insulation in overhead distribution systems. Wishpower manufactures the insulator with a high-strength fiberglass core rod, silicone rubber housing and corrosion-resistant end fittings. Its lightweight structure, pollution resistance and weathering performance make it suitable for new 10kV lines, distribution network upgrades and the replacement of conventional porcelain or glass insulators.

1. Product Overview

The Wishpower 10kV composite long rod insulator combines the load-bearing core, external insulation housing and metal end fittings into an integrated structure. It is developed for outdoor overhead lines where stable electrical insulation and mechanical strength are required under changing environmental conditions.

Compared with traditional porcelain and glass insulators, it offers the following advantages:

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

• High-strength fiberglass core rod for reliable tensile load performance.

• Lightweight construction for easier transportation and installation.

• Corrosion-resistant metal end fittings for long-term outdoor operation.

• Flexible creepage distance and fitting configurations.

• Suitable for new installations and replacement projects.

• Adaptable to polluted, humid, coastal and high-altitude operating environments.

2. Core Features

1. Reliable electrical insulation
   The optimized shed profile and creepage distance help maintain insulation performance under rain, fog, dust and industrial pollution.

2. High mechanical strength
   The fiberglass-reinforced core rod withstands conductor weight, wind load and dynamic mechanical stress during line operation.

3. Excellent pollution flashover resistance
   The hydrophobic silicone rubber surface reduces the formation of a continuous conductive water film under wet and contaminated conditions.

4. Lightweight and easy to install
   Its lower weight simplifies transportation, tower handling and installation compared with equivalent porcelain insulators.

5. Strong weathering resistance
   The housing is designed to resist ultraviolet radiation, ozone, rainfall, temperature variation and outdoor aging.

6. Reduced maintenance requirements
   The non-brittle polymeric housing minimizes damage caused by impact and eliminates the porcelain-shattering risk associated with conventional units.

3. Product Structure

1. Fiberglass Core Rod
   The high-strength fiberglass-reinforced epoxy rod is the main load-bearing component and provides tensile and mechanical strength.

2. Silicone Rubber Housing
   The external housing protects the core rod and provides electrical insulation, hydrophobicity, tracking resistance and weathering resistance.

3. Insulating Sheds
   Equal-diameter or alternating shed profiles increase the creepage distance and improve performance in rain and polluted environments.

4. Metal End Fittings
   The end fittings connect the insulator to line hardware and tower structures. Ball, socket, eye, clevis and customized configurations are available.

5. End Sealing System
   The sealed interface between the core rod and metal fittings reduces the risk of moisture and contaminant ingress.

6. Optional Protective Accessories
   Grading rings, arcing devices and other protection accessories can be supplied according to the line design.
