The fibers, 250, 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.
Good mechianical and temperature performance High strength loose tube that is hydrolysis resistant Special tube filling compound ensure a critical protection of fiber PSP enhancing moisture proof Two parallel steel wires ensure tensile strength Small diameter, light weight and friendly installation Long delivery length
