First of Its Kind

Southwire received an order for a 115kV cable with 5000kcmil segmental copper conductor that has enameled strands in the design. This marked the first order for Southwire with this unique conductor design. The enameled strands in the conductor increase the ampacity over that of a traditional conductor design by reducing the physical property known as skin effect, which occurs in all large cable conductors. Southwire drew the individual strands then sent to a third party to apply the enamel coating on the strands. Once production began, the enameled strands were combined with copper strands to make up the segments which eventually run on the drum twister to complete the conductor.
