OPGW/Ground Wire

OPGW CA Aluminum-clad central tube

Application: installation on medium and high-voltage power lines
OPGW CA | Emcab

Optical fiber


Aluminum-clad stainless steel tube filled with water-blocking gel


Stranded wires (Aluminum-clad steel wires and /or aluminum alloy wires)

Up to 96 fibers

Highly corrosion-resistant: ACS wires and aluminum-clad stainless steel tube

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