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. 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.
