The fibers, 250¦ìm, 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. Charicteristic: 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 Wooden drum
