1. A composite core for an electricity transmission cable comprising:

  • a. an inner core comprising a plurality of substantially continuous reinforcing fibers of at least a first type, the fiber type having a modulus of elasticity that exceeds the modulus of elasticity of glass fibers;

    b. an outer core surrounding the inner core comprising a plurality of substantially continuous reforcing fibers of at least a second type, the fibers having a modulus of elasticity of or similar to glass fibers; and

    c. a cured resin matrix, wherein the fibers of the inner and the outer cores are embedded in said resin matrix;

    wherein, the fibers of the outer core are different from the fibers of the inner core and wherein, the fibers of theinner and the outer cores are oriented substantially parallel to the longitudinal axis.
