250μm's fibers are positioned in the central of a loose tube which is made of high modulus plastics and filled with water-resistant filling compound. The tube is wrapped with a layer of the plastic coated steel strip(PSP). Except the tube filling compound, PSP, water-blocking material and the PE sheath, it also has two steel wires in two sides to enhance the crush resistance and flexibility.
