Contact Arm

Lightweight anodized aluminum contact arm – 60% lighter than copper, 40–50% lower cost, ideal for medium-voltage distribution networks.

  • 60% weight reduction significantly lowers structural load, making it perfect for overhead or space-constrained configurations.
  • Anodized surface treatment prevents galvanic corrosion when paired with aluminum busbars, ensuring long-term reliability.
  • Material costs 40–50% lower than copper while maintaining reliable conductivity for standard distribution network applications.
