Product Overview
A 1.5kV insulated crossarm is an electrical support component designed for low-voltage overhead lines, distribution networks, and outdoor power systems. It combines conductor support, electrical insulation, and structural protection in one integrated design. Wishpower 1.5kV insulated crossarm is manufactured with composite insulation materials and weather-resistant silicone rubber, offering lightweight installation, reliable insulation performance, corrosion resistance, and long service life for modern distribution line applications.
Product Overview
Wishpower 1.5kV insulated crossarm is mainly used to support conductors and maintain safe electrical clearance on overhead distribution lines. Compared with traditional metal crossarms and porcelain insulator assemblies, the composite insulated crossarm provides better insulation reliability, easier installation, and lower maintenance requirements.
Key advantages include:
Composite insulation structure with stable electrical performance;
Weather-resistant outer insulation for long-term outdoor operation;
Lightweight design for easier transportation and installation;
Reduced risk of corrosion, leakage current, and flashover;
Suitable for urban distribution networks, rural power grids, and low-voltage overhead lines;
Customizable length, mounting holes, fittings, and mechanical strength.
Core Features
Reliable Electrical Insulation
The 1.5kV insulated crossarm improves insulation between conductors and poles, helping reduce leakage current, flashover, and grounding faults.Lightweight Composite Design
Compared with conventional steel crossarms, the composite structure is lighter and easier to install, making it suitable for line renovation and fast construction projects.Excellent Weather Resistance
Silicone rubber insulation provides hydrophobicity, UV resistance, aging resistance, and pollution resistance for outdoor environments.Stable Mechanical Support
The product is designed to withstand conductor load, wind load, and normal mechanical stress during long-term operation.Lower Maintenance Cost
Composite insulated crossarms are not easy to corrode and can maintain good insulation performance under polluted conditions, reducing routine maintenance frequency.Flexible Line Compatibility
It can be applied to 0.4kV, 1.5kV, and selected low-voltage distribution systems with different conductor and pole configurations.
