ABSTRACT:
An electrical cable of conventional or retractable helical coil form which is relatively small in diameter and sufficiently flexible to be used to advantage on a tractor-trailer to connect the power supply on the tractor with the electrical system carried by the trailer has a polymeric sheath, an insulated 10 gauge stranded conductor substantially coaxial with the sheath, four to six insulated stranded 12 gauge conductors substantially evenly spaced about the periphery of the 10 gauge conductor, a plurality of uninsulated stranded conductors of 14 gauge disposed between the smaller insulated conductors, filler material filling the spaces between the conductors and preferably a plastic film helically wound about the conductors. The 12 and 14 gauge conductors are helically wound about the 10 gauge conductor. The assembly of conductors, filler and plastic film combine to form a cable having a substantially circular cross-section and substantially fill the sheath. The cable is preferably coiled into a self-storing configuration.
