InSky OPGW

InSky OPGW C part no.
0112
Optical Ground Wire Central loose tube (C)

An excellent choice when low weight and a small diameter are more important than rated breaking strength (RBS) and short circuit current resistance. Often used to replace existing conventional 3/8 inch HS/EHS groundwire.

Optical fiber

2

Stainless steel tube filled with water-blocking gel

3

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

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

Up to 96 fibers

Aluminum-clad steel wires are corrosion-resistant

Optical ground wire (OPGW) shields high-voltage conductors from lightning strikes

Aluminum alloy wires provide conductivity for fault current
