InSky OPGW

InSky OPGW C 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.

InSky OPGW C (Optical Ground Wire Central Loose Tube) is a perfect choice if you are looking for a low weight and a small diameter cable for your fiber optic project or need to replace existing conventional 3/8 inch HS/EHS ground wire. OPGW C manufactured by Incab is a cost-effective solution. It can have up to 96 fibers and is highly corrosion-resistant. Stainless steel tube provides superior protection for the fibers. Small diameters (from 0.315 to 0.709 in) are mechanically and electrically efficient.

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.
