ABSTRACT:
A composite corrugated electrical cable is provided in accordance with the teachings of the instant invention wherein a plurality of corrugated tubular conductors are concentrically positioned with respect to each other, each of such tubular conductors having corrugations that differ from those of the immediately adjacent tubular conductors in wave pitch, shape, depth or longitudinal separation. The corrugation arrangements permit differential longitudinal displacement between adjacent tubular conductors for achieving a composite cable of high flexibility. Further, various corrugation protrusions engage the adjacent tubular conductors to provide radial spacial separations between the adjacent tubular conductors thus providing an intermediate path through which a cooling medium may be passed for increasing the heat dissipation and the power capacity of the electrical cable.
