产品详情
Wishpower line pin composite insulator is made of a high-strength fiberglass core rod, silicone rubber housing and metal end fittings. It is designed for medium-voltage and high-voltage overhead distribution lines where reliable insulation and mechanical support are required.
Compared with traditional porcelain pin insulators, composite pin insulators are lighter, easier to install and more resistant to pollution, moisture, salt fog and outdoor aging.
Main advantages include:
Lightweight structure for easier transportation and installation.
Silicone rubber housing with excellent hydrophobicity and pollution flashover resistance.
Fiberglass core rod for stable mechanical strength.
Suitable for distribution lines, grid upgrades and outdoor electrical projects.
Customizable voltage rating, creepage distance and fitting design.
Core Features
Reliable insulation performance
The line pin composite insulator provides good power frequency withstand capability and lightning impulse resistance, helping improve the safety of overhead power lines.Excellent pollution resistance
The silicone rubber surface offers hydrophobicity and hydrophobicity transfer, maintaining insulation performance in dusty, humid, coastal and industrial environments.Stable mechanical strength
The epoxy fiberglass core rod provides strong mechanical support against conductor load, wind pressure, vibration and outdoor stress.Strong aging resistance
The outer insulation material is resistant to UV radiation, ozone, tracking, erosion and weather aging, making it suitable for long-term outdoor operation.Easy installation and maintenance
The lightweight structure reduces installation workload and helps lower maintenance costs.Adaptability to harsh environments
It can be used in high-altitude areas, heavy pollution zones, coastal regions, humid environments and areas with large temperature differences.
Product Structure
A line pin composite insulator usually consists of the following parts:
Silicone rubber housing
Provides external insulation protection with hydrophobicity, pollution resistance and weather resistance.Epoxy fiberglass core rod
Works as the main load-bearing component, ensuring mechanical strength and structural stability.Metal end fittings
Usually made of hot-dip galvanized steel or customized metal fittings for connection with crossarms and line hardware.End sealing system
