PP winding rope, that is, polypropylene winding rope, has physical and chemical properties such as light weight, non-hygroscopicity, non-toxicity, elasticity, strong tension, mildew resistance, seawater corrosion resistance, and temperature resistance. These characteristics make PP winding rope an ideal material for the outer layer protection of submarine cables.
2. The role of PP winding rope in submarine cables
Anti-corrosion protection:
Resist seawater corrosion: As one of the outer materials of submarine cables, PP winding rope can directly contact seawater, and its seawater corrosion resistance effectively extends the service life of submarine cables.
Multi-layer protection system: In the protection system of submarine cables, PP winding rope usually works together with multi-layer materials such as asphalt, steel wire armor, and lead sheath to form a solid protective barrier to protect cables from seawater erosion in all directions.
Enhance mechanical strength:
Improve pressure resistance: Submarine cables need to withstand huge underwater pressure. The combination of PP winding rope and steel wire armor and other materials significantly enhances the mechanical strength of the cable, enabling it to work stably in deep-sea environments.
Prevent external force damage: The submarine environment is complex and changeable, and there are various potential external force damage factors, such as ship anchor chains, submarine geological movements, etc. The addition of PP winding rope improves the overall anti-destruction ability of the cable and reduces the risk of cable damage caused by external forces.
Improve construction convenience:
Easy to wind and fix: PP winding rope has good winding and fixation, which is convenient for installation and fixation during the construction of submarine cables, improving construction efficiency and quality.
In summary, PP Winding Rope For Submarine Cable does put on protective armor for submarine cables. Through its unique material properties and important role in the cable protection system, it effectively extends the service life of submarine cables and improves their safety and stability. At the same time, the addition of PP winding rope also improves the convenience and efficiency of submarine cable construction. Therefore, PP winding rope plays an indispensable role in the protection of submarine cables.
