1.Purpose:It's designed to replace traditional wood or steel cross-arms, providing both mechanical support and electrical insulation.
2.Material: Made from fiberglass-reinforced resin and covered with weather-resistant materials like silicone, it's lightweight yet strong and resistant to electrical tracking, corrosion, and UV radiation.
3.Advantages:
1)Weight Reduction: They are significantly lighter than traditional cross-arms, reducing the load on poles and towers.
2)High Mechanical Strength: Designed to withstand high loads, they contribute to the overall stability of the power line.
3)Corrosion Resistance: Unlike metal, composites do not corrode, which extends their lifespan and reduces maintenance.
4)Electrical Performance: They have excellent insulation properties and are resistant to electrical tracking.
5)Ease of Installation: Their lightweight nature simplifies transportation and installation processes.
