Used by electric utilities on transmission lines with the voltage of 35 kV and higher for creating optical communication lines and protecting the power lines from lightning strikes.
Applied for aerial installation on distribution and power transmission lines for building long distance optical communication systems.
Used for distributed fiber optic sensing in different applications.
Used for indoor and outdoor applications where fire resistance is a must. Remain functional under direct flame for at least 180 minutes.
Applied in ducts, conduits and trays with no risk of rodent attacks. Can also be lashed.
Designed for high reliability in harsh environments with potential mechanical impact. Applied in all ground types, swamps, and harsh rivers.
Designed for air blowing in ducts and microducts for building reliable underground communication networks.
Designed for underwater application with increased crush and tensile loads.

Used for cost-effective one-step aerial installation mostly in rural areas where the spans between poles are not long .
Applied in substations for control purposes.
Used to create communication lines between the common distribution box and a location inside the building (including vertical runs), between entrances or corridors in office buildings.
Applied for aerial installation on transmission towers, lightning poles, between buildings and structures for communication networks in rural areas.
An excellent design for moderate to high fault current capacities and when ease of splice prep is especially important.
Central strength member (fiberglass reinforced plastic)
PBT loose tubes filled with water-blocking gel
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.
