Stranded Loose Tube Light Armored Cable – GYTA

Central Strength Member is Steel Wire

Cable Structure:

The 250um bare fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of the core as a metallic strength member. Tubes and fillers are stranded around the strength member into a compact and circular cable core. An aluminum polyethylene Laminate (APL) is applied over the cable core, which is filled with the filling compound to protect it from water ingress. Then the cable is completed with a PE sheath.
