GYTC8A

GYTC8A

The fibers,250um,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. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.

GYTC8A Details

Characteristics:
High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cost.
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
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
