Abstract
A composite core for an electrical cable, the composite core defining a longitudinal axis that defines a center of the composite core, the core comprising a plurality of longitudinally extending reinforcing fibers embedded in a resin matrix, the fibers oriented substantially parallel to the longitudinal axis and a non-conductive insulating layer surrounding the plurality of longitudinally oriented fibers. The insulating layer may further comprise a plurality of glass fibers. The insulating layer may also comprise a type of resin, including for example, thermosetting resin or thermoplastic resin.
