Cable null line center public for the high tension

摘要

PROBLEM TO BE SOLVED: To provide a cable for high-voltage electronics which can improve corona resistance without increasing its outer diameter. ;SOLUTION: An internal semiconductive layer 16 and a high-voltage insulator 17 are fitted in order around the outer periphery of a cable core part 11 formed by stranding two lines of low-voltage insulation line cores 14 which extrudingly- covers fluororesin 13 on a conductor 12 and two lines of bare conductors 15. Semiconductive topping tape is wound around them, and heat treatment is conducted to form an outer semiconductive layer 18. A shielding layer 19 and a plastic sheath 20 are fitted on the outer semiconductive layer 18.;COPYRIGHT: (C)1999,JPO
