<p><P>PROBLEM TO BE SOLVED: To provide a high-voltage cab tire cable, wherein an extrusion-coated inner layer sheath adheres (contacts closely) properly only to an ground wire core and an optical fiber unit on an outer circumference where a power wire core and other wire core comprising the ground wire core and the optical fiber unit are twisted. <P>SOLUTION: In the high-voltage cab tire cable, a power wire core 20 and other wire cores 25, 30 sequentially forming an inner conductor 21 consisting of inner semiconductor layers, an insulator 22, and an outer conductor 24 consisting of outer semiconductor layers around a copper conductor 21 are twisted together, and an inner layer sheath 11 and an outer layer sheath 13 are sequentially formed on the outer circumference. The adhesion among other wire cores 25, 30 and the inner layer sheath 11 is stronger than that between the power wire core 20 and the inner layer sheath 11. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
