To meet user requirements and reduce cable tension by at least 20%, Nexans evaluated methods such as modifying the cable structure, increasing sheath stiffness, or using a lubricant. The evaluation results indicated that the third option could reduce cable tension by 23%.
There is no compromise on flexibility, cable characteristics, outer diameter, or weight; all that's needed is to add a fatty acid additive to the cable's outer sheath compound during extrusion. This additive creates a very smooth surface, making the cable easier to move and slide into the correct position.
In Vietnamese shipyards, the frictional resistance of cables increases with high ambient temperatures. This can be addressed by adding a sheath, but the increased rigidity creates other installation problems.
After evaluating two options, Nexans determined that a slip-enhancing additive was the best way to reduce cable tension without altering cable performance. Nexans then examined the economic feasibility and conducted small-scale internal trials to confirm its effectiveness. Finally, Nexans visited shipyards to demonstrate the new easy-pull cable to all potential customers.
Depending on the terrain, marine/shipboard cables can be categorized into different standards, such as NEK606 (Norwegian standard), BS6883 (British standard), IEEE45 (American standard), and IEC60092 (international standard), although these standards are generally applicable and used globally. Nexans' main competitors and most cable manufacturers adhere to the NEK606 standard, but for this type of halogen-free mud-resistant cable, the differences are minimal. In response to the needs of shipbuilders in the Vietnamese market, Nexans created some differences and applied them to new cables.
