ELECTRICAL CABLE ADAPTED FOR USE ON A TRACTOR-TRAILER Abstract of the Disclosure 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 peri- phery 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 assem- bly of conductors, filler and plastic film combine to form a cable having a substantially circular cross-section and sub- stantially fill the sheath. The cable is preferably coiled into a self-storing configuration.
