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. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides. 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 Two parallel steel wires ensure tensile strength PE sheath protects cable from ultraviolet radiation Small diameter, light weight and friendly installation Long delivery length
