Product Overview
The 35kV line post composite insulator is designed for 35kV overhead distribution lines, providing reliable insulation, conductor support and mechanical fixing. Wishpower manufactures this product with a high-strength fiberglass core, silicone rubber housing and durable metal end fittings for outdoor high voltage applications.
Wishpower 35kV line post composite insulator is a high-performance insulation component for medium and high voltage distribution systems. It is widely used as an alternative to traditional porcelain or glass insulators due to its lighter weight, better pollution resistance and easier installation.
Main advantages include:
High temperature vulcanized silicone rubber housing with excellent hydrophobicity.
Epoxy fiberglass core with strong mechanical and electrical performance.
Hot-dip galvanized end fittings for improved corrosion resistance.
Compact structure suitable for 35kV overhead line and distribution projects.
Lightweight design to reduce transportation, installation and maintenance costs.
Key Features
Excellent Pollution Flashover Resistance
The silicone rubber housing provides strong hydrophobicity and helps maintain stable insulation performance in polluted or humid environments.High Mechanical Strength
The fiberglass core offers reliable bending strength and mechanical support for long-term line operation.Lightweight and Easy Installation
Compared with porcelain insulators, composite insulators are lighter and easier to handle during transportation and field installation.Strong Aging Resistance
The silicone rubber sheds provide good resistance to UV radiation, ozone, moisture and outdoor weathering.Reliable Operating Performance
The integrated structure helps reduce flashover risk, breakage and maintenance frequency in distribution networks.
Product Structure
The 35kV line post composite insulator usually consists of the following components:
Insulating Core: Made of epoxy fiberglass rod, providing mechanical strength and internal insulation.
Silicone Rubber Housing: Protects the core and provides external insulation.
Shed Design: Increases creepage distance and improves performance under wet and polluted conditions.
Metal End Fittings: Used for connection with crossarms, brackets or line hardware.
Sealing System: Prevents moisture from entering the interface between the core and fittings.
Hot-Dip Galvanized Hardware: Improves corrosion resistance for outdoor service.
