InSky OPGW CA Optical Ground Wire Central Aluminum-clad loose tube (CA)

An excellent choice when moderate fault current capacity is needed in a compact diameter. It is also especially well-suited for highly corrosive locations, such as coastal areas.


Optical fiber


Aluminum-clad stainless steel tube filled with water-blocking gel


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
