OPGW Center Aluminum-Clad Stainless Steel Tube

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

OPGW Center Aluminum-Clad Stainless Steel Tube

  • 3
    Stranded wires (Aluminum Clad Steel wires and /or aluminum alloy wires).
  • 2
    Aluminium-clad stainless steel tube filled with water-swellable gel.
  • 1
    Optic fiber.


Up to 48 fibers in a tube

100% corrosion-resistant: ACS wires and stainless steel tube. Suitable for areas with highly corrosive environments.

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.
