Claims16
High voltage electrical transmission cable comprising:
- at least one central reinforcing element extending along the cable, said reinforcing element being encircled by at least one electrically conductive element extending along the cable, said electrically conductive element formed as an assembly of strands, each strand having a cross section with a trapezoidal or “Z” shape being intended to transmit power for high voltage transmission, wherein said central reinforcing element is a tubular body comprising at least one layer of a nonmetallic material, and at least one layer of a metallic material the metallic material being the innermost layer of said nonmetallic tubular body while maintaining a hollow central core of said tubular body.
High voltage electrical transmission cable comprising:
- at least one central reinforcing element extending along the cable, said reinforcing element being encircled by at least one electrically conductive element extending along the cable, said electrically conductive element being intended to transmit power for high voltage transmission,
- wherein said central reinforcing element is a tubular body comprising at least one layer of a nonmetallic material, and
- wherein the center of the electrical cable comprises a longitudinal orifice having an inside diameter of about 5 to 80 mm.
High voltage electrical transmission cable comprising:
- at least one central reinforcing element extending along the cable, said reinforcing element being encircled by at least one electrically conductive element extending along the cable, said electrically conductive element being intended to transmit power for high voltage transmission,
- wherein said central reinforcing element is a tubular body comprising at least one layer of a nonmetallic material, and
- wherein the thickness of said nonmetallic layer ranges from 5 to 50 mm.
High voltage electrical transmission cable comprising:
- at least one central reinforcing element extending along the cable, said reinforcing element being encircled by at least one electrically conductive element extending along the cable, said electrically conductive element being intended to transmit power for high voltage transmission,
- wherein said central reinforcing element is a tubular body comprising at least one layer of a nonmetallic material, and
- wherein the weight per unit length of said nonmetallic layer range from 0.05 to 0.5 kg/m.
