Unitube Light-armored Cable ( GYXTW )

FlyingFiber’s GYXTW unitube light-armored cable provide 250μm fibers, 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.

1). Good mechanical and temperature performance.

2). High strength loose tube that is hydrolysis resistant.

3). Special tube filling compound ensure a critical protection of fiber.

4). Crush resistance and flexibility.

5). PSP enhancing moisture-proof.

6). Two parallel steel wires ensure tensile strength.

7). Small diameter, light weight and friendly installation.

8). Long delivery length.

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