Abstract

The invention discloses a heat-resistant rare earth aluminum alloy conductor for a power cable, and the conductor comprises an outer protection layer, the inner wall of the outer protection layer is fixedly connected with an armor layer, the inner wall of the armor layer is fixedly connected with an inner lining layer, the inner wall of the inner lining layer is fixedly connected with a wrapping tape, the inner wall of the wrapping tape is fixedly connected with a filling layer, the inner wall of the filling layer is fixedly connected with an insulating layer, and the inner wall of the insulating layer is fixedly connected with an aluminum alloy conductor. The heat-resistant rare earth aluminum alloy conductor prepared by the processing technology is compatible with the characteristics of the 8030 conductor and the 8A07 conductor at the same time, so that the heat-resistant rare earth aluminum alloy conductor can be used in a power cable and has the flexibility of an 8030 rod material and the heat resistance of the 8A07, the resistivity of the conductor at 20 DEG C is not greater than 29.73 n[hom].m, the tensile strength is 110-145MPa, and the elongation is not less than 6%. The heat-resistant rare earth aluminum alloy prepared through the processing technology overcomes the defects that a common aluminum alloy cable is not heat-resistant, and the current-carrying capacity is reduced due to temperature rise, self-crosslinking materials are selected in the aspect of materials, cost is reduced, pollution is reduced, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a heat-resistant rare earth aluminum alloy conductor for power cables and a processing technology thereof. Background technique [0002] A cable is an electrical energy or signal transmission device, usually a rope-like cable twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and often surrounds a Twisted in the center, the entire exterior is covered with a highly insulating cover.
