Patent ID: 8532453

Claim:
A high voltage cabtire cable comprising: power cores each of which comprises an inner semi-conductive layer, an insulation, and an outer semi-conductive layer successively provided in this order around a copper conductor; other cores stranded together with the power cores, the other cores comprising a grounding core and an optical fiber unit; and an inner sheath and an outer sheath successively provided in this order around peripheries of the power cores and the other cores stranded together, wherein an adhesion force between the other cores and the inner sheath is greater than an adhesion force between the power cores and the inner sheath, wherein the outer semi-conductive layer of each of the power cores comprises nitrile-butadiene rubber based material, the grounding core comprises a conductive coating layer comprising a chloride of polymer, the optical fiber unit comprises a binder tape provided around an outer periphery of an outer sheath of the optical fiber unit, the binder tape comprises a single-sided rubber-coated fabric tape, and the inner sheath comprises a chloride polymer, wherein the inner sheath is bonded to the grounding core and the optical fiber unit, and wherein the single-sided rubber coated fabric tape comprises one side coated with rubber and an other side which is not coated with the rubber and is bonded to the inner sheath.
