OPGW S | Emcab
1

Central strength member (aluminum-clad Steel wires or aluminum alloy wires)

2

Optical fiber

3

Stainless steel tube filled with water-blocking gel

4

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

5

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

Up to 432 fibers

Aluminum-clad steel wires are corrosion resistant

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