Electrical Transmission Cables With Composite Cores

An electrical cable comprising:

• (a) a cable core comprising at least one composite core, the composite core comprising:
• (i) at least one rod comprising a plurality of consolidated thermoplastic impregnated rovings, the rovings comprising carbon fibers and a thermoplastic matrix that embeds the carbon fibers, the carbon fibers having a ratio of ultimate tensile strength to mass per unit length of greater than about 1,000 MPa/g/m, wherein the thermoplastic matrix comprises a polyphenylene sulfide, and wherein the rod comprises from about 30 wt. % to about 75 wt. % carbon fibers;
• and
• (ii) a capping layer surrounding the at least one rod, wherein the capping layer contains less than 5 wt. % of carbon fibers;
• and
• (b) a plurality of conductive elements surrounding the cable core.
