SK Stranded Loose Tube Armored Cable（GYTA53）
Features
•Description
The fibers, 250μm, 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 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. After the PSP is longitudinally applied over the
inner sheath, the cable is completed with a PE outer sheath.
•Characteristics
• Good mechanical and temperature performance
• High strength looes 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 barrier
- PSP enhancing moisture-proof
- Water-blocking material
•Standards
GYTA53 cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
