Aluminum-clad steel wires and/or aluminum alloy wires

OPGW marking: unique and the only one in the industry to know the exact footage and identify the design type

Convenient splice preparation

Up to 144 fibers

Highly corrosion-resistant: ACS wires and aluminum pipe

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

Aluminum alloy wires provide conductivity for fault current

InSky OPGW AP (Optical Ground Wire Aluminum Pipe) is a great choice for moderate to high fault currents. Aluminum pipe has excellent electrical properties. PBT loose tube design can be considered as an advantage as it is perceived easier to splice prep plastic buffer tubes versus stainless steel loose tubes. It can have up to 144 fibers and is highly corrosion-resistant.

All Incab OPGW cables have a proven design life of 50 years. They are a wholesome 3-in-1 solution for the utilities and telecommunication industry being a ground wire that enables efficient power distribution grids, a telecom medium with high-speed optical fiber for data transmission and additionally for power line monitoring. Moreover, they don’t require additional costs when placing fiber optic communication lines on power lines.

Incab OPGW cables have been tested by the independent laboratory “Kinectrics” (Canada) according to IEEE 1222 standard.
