ELECTRICAL CABLES HAVING LOW RESISTANCE AND HIGH FLEXIBILITY AND METHODS OF MAKING SAME

摘要

An electrically conductive cable (100) includes a number of conductive strands (102, 104, 106) which are twined to form a wire rope (108) without a central core. The wire rope (108) is drawn through a die (110) to reduce its diameter until the outer surface of the cable (100) is smooth and the cross section of the cable (100) is substantially circular. According to a presently preferred embodiment, the electrically conductive cable (100) is successively drawn through four dies (110) of decreasing diameter so that the overall diameter of the wire rope (108) is reduced by 30-40 %. The resulting electrically conductive cable (100) has the tensile strength advantage and the low resistance advantage of a solid conductor with the flexibility advantage of a wire rope cable. In addition, the smooth outer surface of the electrically conductive cable (100) according to the invention is easily insulated with an extruded material.
