Light-armored Cable（GYXTW）

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. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath.

Characteristics

Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Crush resistance and flexibility
PSP enhancing moisture-proof
Two parallel steel wires ensure tensile strength
Small diameter, light weight and friendly installation
Long delivery length

Standards

GYXTW cable complies with Standard YD/T 769-2003.
