Electrical cable adapted for use on a tractor trailer
First Claim
1. An electrical cable comprising a polymeric sheath, a first insulated stranded wire conductor disposed in the sheath and substantially co-axial therewith, four to six insulated stranded conductors of smaller gauge than the first conductor disposed about the periphery of the first conductor, uninsulated stranded conductors of smaller gauge than the said smaller insulated conductors, and an electrically insulating filler material disposed in the spaces between the said conductors combining to form a cable which is substantially circular in cross-section tightly enclosed in said sheath.

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.
