Ground Wire (Enhanced Corrosion-resistant Groundwire)

Applied in the construction of fiber-optic link on overhead transmission lines of 35 kV and more.

Ground Wire (Enhanced Corrosion-resistant Groundwire)

  • 3
    Stranded wires (ACS wires and /or aluminum alloy wires)
  • 2
    Stranded wires (ACS wires and /or aluminum alloy wires)
  • 1
    Central strength member (ACS wire)

Advantages

ACS wires are rustproof

Aluminum alloy wires shield the high-voltage conductors from lightning strikes

Mastering the technology of steel module manufacturing and stranding of steel zinc-coated wires allowed us to create a new product: MASS — Metallic Aerial Self Supporting Cable.
