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.
Characteristics
- 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 - Small diameter, light weight and friendly installation
