Stranded Loose Tube Armored Cable (GYTA53)
Overview
The 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 locates in the center of 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 around the cable core, which is filled with the filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. And a PSP is longitudinally applied over the inner sheath, and the cable is covered with a PE outer sheath. After the single-steel wire armored, the cable is finally completed with an outer sheath.
Key Features
- Good mechanical and temperature performance
- Single-steel wire ensures good performance of tensile strength
- High strength loose tube that is hydrolysis resistant
- Special tube filling compound ensure a critical protection of fiber
- Crush resistance and flexibility
- The following measures are taken to ensure the cable watertight:
Steel wire used as the central strength member
Loose tube filling compound
100% cable core filling
APL moisture
PSP enhancing moisture-proof
