Stranded wires (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

Up to 96 fibers

Enhanced corrosion resistance: ACS wires and aluminum-clad stainless steel tube

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

Aluminum alloy wires provide conductivity for fault current

InSky OPGW CA (Optical Ground Wire Central Aluminum-Clad Loose Tube) is a great choice when moderate short-circuit current capacity in a compact diameter is required. It is also well-suited to areas of high corrosive activity, such as coastal areas. A central loose tube of OPGW CA is an aluminum-clad stainless steel tube and that’s what sets OPGW CA apart from OPGW C. An aluminum-clad stainless steel tube enhances thermal resistance, airtightness, and crush resistance.

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.
