TH2903B - Overhead composite conductor spiral cable - Google Patents

Abstract

Overhead composite conductive strands that have been improved for improved long-term strength and reduced loss-of-life properties. Several optical fiber cables are inserted in the splitter pulley, which surrounds the Will be entangled with conductive strands The optical fiber cable contains fluorine at its very youngest, one core and one wrap layer Each fiber optical cable is enclosed in a protective layer. And there is a flexible, heat-resistant material placed between each fiber optical cable and the bottom of the spiral to hold the movement of the optical fiber within the spiral in the direction. Lengthwise

Claims (8)
