A kickless water cooled cable includes six alternate polarity conductor strands and paired terminal lugs at each end which are semi-circular and mutually insulated along a diameter, the inner end of each lug including a projection having parallel flattened strand connecting surfaces. The projections are offset from each other along the diameter of insulation, the opposite offset surfaces providing a radially outer and a recessed inner connecting surface on the respective lugs. A single strand is connected to the outer surface while a dual strand termination is connected to the recessed inner surface, the single strand lying between the dual strand to form the alternate polarity conductor strands. The strands are separated by a star separator and enclosed in a hose through which water is circulated. The projections include angled inner ends to provide greater contact area, the dual strand termination includes an angled offset portion parallel to yet clearing the angled surface of the opposite lug. To improve the electrical connections and its useful life at least the dual strand connection surface has an abutment shoulder along its outer edge running the length thereof. The dual strand fitting connection is also provided with two axially spaced fasteners, a knurled surface and a solder connection. The star separator includes a stiffener with graduating degrees of stiffness to reduce stress on the connections. All of the above improvements enhance the electrical connections and lengthen the service life of the cable.
