Description
Our FRP Insulated Cross Arm is a high-performance electrical insulation component engineered for overhead power distribution and transmission lines. Constructed from fiberglass-reinforced polymer (FRP), it provides superior electrical insulation, mechanical strength, and environmental durability compared to traditional wooden or steel cross arms.
Key Features
- Excellent Insulation Performance: High dielectric strength and insulation resistance to prevent leakage current and flashover.
- Lightweight & High Strength: High tensile and flexural strength with a much lower weight than steel, reducing installation and transportation costs.
- Corrosion & Weather Resistance: Resistant to rust, rot, UV radiation, moisture, and chemicals, ensuring long-term reliability in harsh outdoor environments.
- Low Thermal Expansion: Stable dimensions under temperature fluctuations, minimizing structural deformation.
- Non-Conductive & Non-Magnetic: Eliminates electromagnetic interference and eddy current losses.
- Easy Installation: Standardized hole pattern and design for quick, tool-efficient mounting on utility poles and transmission towers.
Applications
| Application Scenario | Applicable Voltage Range (AC) | Core Advantages in Scenario |
|---|---|---|
| 10kV Overhead Distribution Lines | 10kV | Lightweight design reduces pole load; corrosion resistance for rural/coastal areas |
| 35kV Medium-Voltage Lines | 35kV | High insulation strength prevents flashover; low thermal expansion for stable operation |
| Communication Utility Poles | 0-10kV | Non-conductive property avoids electromagnetic interference with communication equipment |
| Street Lighting Poles | 0.4kV-10kV | UV resistance for outdoor long-term use; easy installation reduces labor cost |
| Industrial Electrical Structures | 10kV-35kV | Chemical corrosion resistance for industrial environments; high mechanical strength |
Technical Advantages
