LOW SHRINKAGE SUBMARINE POLYPROPYLENE YARN AND A SUBMARINE CABLE USING THE SAME FOR MAINTAINING MATERIAL PROPERTIES REGARDLESS OF EXTERNAL CHANGES DUE TO SHRINKAGE

摘要

PURPOSE: Low shrinkage submarine polypropylene yarn and a submarine cable using the same are provided to maximize elongation efficiency by implementing an elongating process with a chain structure of a polymer which is composing a polypropylene sheet elongated.;CONSTITUTION: A submarine cable(1) includes twisted submarine polypropylene yarn(10), submarine polypropylene yarn(20), an outside protection layer(30), an interior layer(40), and an exterior layer(50). The inside of the interior layer is filled with the submarine polypropylene yarn. The twisted submarine polypropylene yarn is wound between the interior and the exterior layer. The outside protection layer is formed at the outside the exterior layer. The outside protection layer is made of concrete.;COPYRIGHT KIPO 2013
