Aluminum conductor composite core reinforced cable and method of manufacture

A composite core for an electrical cable comprising:

• an inner core consisting of a plurality of substantially continuous reinforcing fibers, the fibers having a tensile strength that exceeds the tensile strength of glass fibers;
• an outer core surrounding the inner core consisting at least in part of a plurality of substantially continuous reinforcing glass fibers;
• and
• a cured resin matrix, wherein the fibers of the inner and the outer cores are embedded therein;
• wherein, the fibers of the inner and the outer cores are oriented substantially parallel to the longitudinal axis.

A composite core for an electrical cable comprising:

• an inner core comprising a plurality of reinforcing carbon fibers and at least a portion of a plurality of reinforcing fibers having a tensile strength in excess of glass fibers;
• an outer core surrounding the inner core comprising a plurality of glass fibers;
• and
• a cured resin matrix, wherein the fibers of the inner and the outer cores are embedded therein;
• wherein, the fibers of the inner and outer cores are oriented substantially parallel to the longitudinal axis.

An electrical cable comprising:

• a composite core further comprising:
• an inner core comprising a plurality of substantially continuous reinforcing fibers of at least a first type, the first type having a tensile strength that exceeds the tensile strength of glass fibers, wherein the fibers are substantially parallel to the longitudinal axis;
• an outer core comprising a plurality of substantially continuous reinforcing fibers of at least a second type, the second type having a tensile strength of or similar to glass fibers, wherein the fibers are substantially parallel to the longitudinal axis;
• and
• a cured resin matrix, wherein the fibers of the inner and the outer cores are embedded therein;
• and
• at least one layer of conductor surrounding said outer core.

A method of transmitting electrical power comprising:

• using a cable comprising a composite core and at least one layer of aluminum conductor surrounding the composite core, the composite core further comprising:
• an inner core comprising a plurality of substantially continuous reinforcing fibers of at least a first type, the first type having a tensile strength that exceeds the tensile strength of glass fibers, wherein the fibers are substantially parallel to the longitudinal axis;
• an outer core comprising a plurality of substantially continuous reinforcing fibers of at least a second type, the second type having a tensile strength of or similar to glass fibers, wherein the fibers are substantially parallel to the longitudinal axis;
• and
• a cured resin matrix, wherein the fibers of the inner and the outer cores are embedded therein;
• and
• transmitting power across the composite cable.
