Abstract
A conductor is suitable for use in a high-voltage cable, and includes an aluminium alloy, in which the aluminium alloy comprises one or more of a group 3, 4 or 5 element and/or a lanthanide, each with a concentration in the range of 0.006 to 0.03% (m/m). The conductor has undergone a thermal treatment at a temperature from the range of 185° C. to 315° C. during a period from the range of 12 hours to 24 hours, so that the conductor has a conductivity of 61% IACS or more.
Claims14
An overhead high-voltage line comprising a conductor, the conductor being formed as a wire or a plurality of wires drawn from wire rod,
- wherein the conductor includes an aluminium alloy,
- wherein the aluminium alloy includes one or several of a group 3, 4 or 5 element and optionally a lanthanide, each with a concentration in the range 0.006 to 0.030%(m/m),
- wherein the conductor has undergone a thermal treatment in the form of the drawn wire or wires at a temperature from within the range 185° C. to 315° C. for a period from within the range 12 hours to 24 hours, wherein the conductor has undergone the thermal treatment before any cabling or stranding of the wire or wires to form the overhead high-voltage line, and
- wherein the conductor has a conductivity of 61% IACS or more.
An overhead high-voltage line comprising a conductor, the conductor being formed as a wire or a plurality of wires drawn from wire rod,
- wherein the conductor includes an aluminium alloy,
- wherein the aluminium alloy includes one or several of a group 3, 4 or 5 element, each with a concentration in the range 0.006 to 0.030%(m/m),
- wherein the conductor has undergone a thermal treatment in the form of the drawn wire or wires at a temperature from within the range 185° C. to 315° C. for a period from within the range 12 hours to 24 hours, wherein the conductor has undergone the thermal treatment before any cabling or stranding of the wire or wires to form the overhead high-voltage line, and
