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.
