core or without a core of higher conductivity if the central core 18 is made of gold it will also possess an inherently higher conductivity and the cable will be less affected by heat than a similar cable without the core because an improved thermal path exists to conduct heat from the core to the surface of the conductor it will also be appreciated that when solder is used as the core the cable may be more easily soldered to an electrical connection or to another cable the above described cable having a conductive filler material among the strands will have increased conductivity and reduced parasitic inductance as compared to a stranded cable of similar size with no filler material increased conductivity will result from the intimate electrical connection established among the strands by the conductive filler material this connection will allow current to flow more freely along the longitudinal axis of the cable rather than along longer and higher resistance paths of individual helical strands in addition by allowing the current to flow parallel to the longitudinal axis parasitic inductance is significantly decreased it will be appreciated that when the cable is used to carry an alternating current the cable will exhibit reduced inductive reactance for these same reasons the methods described above may be applied to a cable having more than three strands for example as shown in fig4 and 5 according to a second embodiment of the invention four copper or aluminum strands 12 14 16 and 20 are twisted around a central core 18 which is preferably made of silver gold or solder the twisted strands are then drawn through a plurality of reducing dies as described in the previously incorporated parent application such that the overall diameter of the twisted.
