Patent ID: 8030572

Claim:
A core for an electrical conductor comprising: an inner core component comprising a strength member formed from a plurality of glass based stranded members in a first resin matrix; an intermediate cladding component surrounding the inner core component and comprising a strength member formed from a plurality of carbon stranded members in a second resin matrix, the second resin matrix being different than the first resin matrix; and an outer cladding component surrounding the intermediate cladding component and comprising a strength member formed from a plurality of glass based stranded members in a third resin matrix, wherein the first resin matrix is dimensionally cured prior to the placement of the intermediate cladding component and the second resin matrix thereon, to in turn, form a substantially uniform boundary between the inner core and the intermediate cladding, and so that the first resin matrix remains separate from the second resin matrix, meeting at a boundary.
