Product Overview
The 10kV line type composite post insulator is designed for conductor support and electrical insulation in 10kV overhead distribution lines. Wishpower manufactures this product with a high-strength fiberglass core, silicone rubber housing and durable metal fittings, making it suitable for urban networks, rural grids and demanding outdoor environments.
Main advantages of Wishpower composite insulators include:
High-quality silicone rubber housing with excellent hydrophobicity and weather resistance.
Strong fiberglass core providing reliable mechanical strength.
Compact structure for easy installation and reduced maintenance cost.
Suitable for 10kV overhead distribution lines, urban grid upgrades and rural power projects.
Customizable creepage distance, mounting size and end fitting design according to project requirements.
Core Features
Excellent anti-pollution performance
The silicone rubber housing provides hydrophobic surface properties, reducing flashover risk in wet and polluted environments.High mechanical strength
The fiberglass core offers strong bending, tensile and impact resistance for long-term line support.Lightweight and easy to install
Compared with porcelain insulators, composite insulators are lighter and easier to handle during field installation.Strong aging resistance
The housing material provides good resistance to UV radiation, ozone, temperature variation and outdoor weathering.Low maintenance cost
The product is not easy to break and maintains stable insulation performance, reducing inspection and replacement frequency.Suitable for harsh environments
It can be used in humid, polluted, coastal, mountainous, sandy and high-temperature-difference areas.
Product Structure
A 10kV line type composite post insulator usually consists of the following components:
Silicone rubber housing
Provides external insulation protection with hydrophobic, anti-pollution, weather-resistant and UV-resistant properties.Epoxy fiberglass core
Works as the main load-bearing component and provides internal insulation strength.Metal end fittings
Usually made of hot-dip galvanized steel or customized anti-corrosion metal materials for connection with crossarms, brackets or conductor clamps.Sealing interface
The connection area between fittings and housing is sealed to prevent moisture ingress and ensure long-term reliability.Shed profile
The optimized shed design increases creepage distance and improves insulation performance under polluted conditions.
