A scandium-aluminum alloy conductor low-voltage rubber-sheathed flexible cable for offshore wind power generation

Abstract

The invention discloses a low-voltage rubber-sheathed soft cable with a scandium-aluminum alloy conductor for offshore wind power generation, which belongs to the field of electric wires and cables, and includes a cable core, a water-blocking wrapping tape and an outer sheath, and the outside of the cable core is wrapped with a water-blocking wrapping The outside of the water-blocking tape is extruded with an outer sheath; the cable core includes 3 power cores, multiple support frames and 1 ground core, and the ground core is placed inside the cable core. In the center, the center of the ground wire core is filled with a ground wire core conductor, and the outside of the ground wire core conductor is extruded with a ground wire core insulating sleeve, and the outside of the ground wire core is equipped with a support frame. The power wire cores are respectively placed between the supporting frames. The invention effectively fixes and supports the wire cores by adopting a spirally arranged support frame, avoids mutual extrusion and deformation of the wire cores, and effectively increases the structural strength, elongation and tear resistance of the cable core, etc., and solves the traditional cable bending performance Poor shortcomings, and effectively applicable to low-voltage cables, easy for long-term promotion.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to a low-voltage rubber-sheathed flexible cable with a scandium-aluminum alloy conductor for offshore wind power generation. Background technique [0002] With the continuous development of my country's industry and the rapid development of wind power generation, the amount of cables used is also increasing. However, cold-resistant, corrosion-resistant, flame-retardant, and water-resistant cables suitable for offshore wind power generation have not yet appeared; existing cables The main raw materials of the cable are insulation, sheath and conductor. The main component of the cable conductor is copper, which accounts for about 70% of the total copper consumption in the production industry. With the depletion of China's copper mine resources, my country's copper resources are very short, of which 80% of them need to be imported, which is highly dependent; therefore, with the ri...
