Marine ropes can be used in all directions due to their various superior properties. High quality tow rope, high strength traction rope. Extra high strength, light weight and easy to operate. Although the one-time investment is high, as long as the rope is properly maintained, its service life is 2-3 times that of other ropes. Heavy duty ropes used in the fishing and coastal industries. Offshore waterlogging systems, rescue systems, offshore oil platform systems, berthing, anchoring, embedded mooring lines, marine seismic surveys, submarine cables, sailing cables, leg ropes, halyards, sail ropes, strings, gliding ropes, Umbrella ropes, climbing ropes, sail ropes, shooting bow strings, etc.

Ropes, sail ropes for the navy, parachute ropes and other sailing ropes for paratroopers, helicopter slings, rescue ropes, and various sailing and maneuvering strong ropes for the army and armored forces. Due to their high strength, small diameter and weight It is light, easy to carry and operate, and is suitable for use in marine cables in many aspects. Strong wire traction ropes and marine cables are high-strength insulated ropes commonly used in line construction, especially when installing protection systems for important crossing objects, in dense forest areas with high environmental protection requirements and line projects with complex or important crossing objects. In the online process, its application is more frequent.

What are the benefits of marine cables in the power grid construction process? Understanding its benefits will help us use ship cables more rationally:

1) When used in difficult-to-operate areas with paragliders, remote-controlled airships, helicopters, etc., the electric traction rope has a diameter of only 3mm and a weight of only 4.5 grams per meter when the breaking force is close to one ton. It has been used more and more widely. For example: Taizhou Bridge primary pay-off and secondary traction.

2) Use a heavy-duty electric traction rope to pull the cable across the Yangtze River and Yellow River in one go. The cable floats on the water and has the same strength as the steel cable when the diameter is the same. This method greatly improves the efficiency of cross-river wiring.

3) It is used as a safety net load-bearing cable and a traction cable in a live span. Because the electric traction rope is light in weight (unit length at equal strength, the weight is only 1/8~1/10 of the steel cable). It also has good insulation and has passed 640Kv withstand voltage test). Electric traction ropes have been widely used in live crossing projects. Its application in balancing spans, towers, insulation, hoisting, and safety ropes for equipment on towers ensures the safety of construction personnel and equipment and improves construction efficiency.
