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 two sides PSP are longitudinally applied over the outer loose tube. Steel wires and loose tubes filled with water proof compound to ensure compact and longitudinally water blocking ,this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene(PE) sheath to be figure 8 structure.
1.High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cost
6.Small diameter, light weight and friendly installation
7.Long delivery length and low price.
