Characteristics and working temperature of marine ropes

The high tensile strength of marine ropes can effectively improve load-bearing capacity. Its low elongation can effectively control sag, making the sag drop of the bearing cable as small as possible under load, ensuring that the clearance distance between the sealing device and the live power line meets safety requirements.


The good insulation and moisture-proof performance of marine ropes can ensure the safety of personnel and equipment during live crossing construction.


Sheathed marine ropes are not affected by breeze vibration, strand breakage and Strength reduction.


The material of marine ropes is light, and under the same breaking tensile strength conditions, the weight per meter of marine ropes is only 15% of that of steel wire ropes. Using marine ropes is beneficial for reducing labor intensity and improving work efficiency.


Marine ropes have excellent resistance to bending fatigue, wear resistance, weather resistance, UV protection, and chemical corrosion, which are beneficial for cyclic use in crossing construction.


The main performance of marine ropes:


Lightweight, floating on the water surface, about 87.5% lighter than steel wire ropes of the same diameter.


The strength is high in the world, about 1.5 times higher than that of steel wire ropes of the same diameter.


Excellent durability, seawater resistance, and chemical resistance, resulting in repeated exposure to UV radiation and temperature differences, while maintaining the same quality of use.


The operation is convenient, fast, safe to use, and the operation time is short, such as the military's ability to maneuver quickly in specific situations.


Strong wear resistance:


Wear resistance (especially among all plastics), low coefficient of friction (second only to PTFE), strong resistance to low temperatures (can still maintain useful impact resistance, toughness, and ductility under liquid helium temperature -269 ℃ without fracture), low density, light weight (density less than water,<1 g/cm3), low water absorption, physiological inertness (most grades can be used for contact with food), and FDA certified moderate mechanical strength, rigidity Good creep resistance and excellent machining performance. Excellent corrosion resistance, chemical resistance, and high energy radiation resistance (gamma ray, X-ray). Good electrical performance.


Working temperature:


Extensive cold and heat resistance: It can maintain a predetermined mechanical strength at -60 ° C, with a heat resistance temperature of 80-100.
