Description
Our Fiberglass Composite Cross Arm is a high-performance electrical insulation component designed for overhead power distribution and transmission lines. It replaces traditional wooden and steel cross arms with superior electrical, mechanical, and environmental properties.
Key Features
- High Insulation Performance: Excellent dielectric strength and insulation resistance, effectively preventing leakage current and flashover.
- Lightweight & High Strength: High tensile and flexural strength, yet significantly lighter than steel, reducing installation and transportation costs.
- Corrosion & Weather Resistance: Resistant to rust, rot, UV radiation, moisture, and chemical exposure, ensuring long service life in harsh outdoor environments.
- Low Thermal Expansion: Stable dimensions under temperature variations, minimizing structural deformation.
- Non-Conductive & Non-Magnetic: Eliminates electromagnetic interference and avoids eddy current losses.
- Easy Installation: Standardized hole pattern and design for quick, tool-efficient mounting on poles and towers.
Applications
Ideal for overhead distribution lines, communication poles, street lighting, and industrial electrical structures in 10kV–35kV power systems.
Technical Advantages
- Long service life (25+ years)
- Low maintenance requirements
- Compliant with IEC, GB, and other industry standards
- Environmentally friendly and recyclable
The fiberglass composite cross arm delivers reliable electrical insulation and mechanical support, making it a durable, cost-effective upgrade for modern power infrastructure.
