Scandium aluminum alloy conductor low-voltage rubber jacketed flexible cable for offshore wind power generation

Abstract

The invention discloses a scandium aluminum alloy conductor low-voltage rubber jacketed flexible cable for offshore wind power generation, which belongs to the field of wires and cables. The scandiumaluminum alloy conductor low-voltage rubber jacketed flexible cable comprises a cable core, a water-blocking wrapping tape and an outer sheath. The water-blocking wrapping tape is wrapped on the outerside of the cable core. The outer sheath is extruded on the outer side of the water-blocking wrapping tape. The cable core comprises three power wire cores, a plurality of supporting frames and a ground wire cores. The ground wire cores are arranged in the center of the interior of the cable core. The centers of the interiors of the ground wire cores are filled with a ground wire core conductor.The outer side of the ground wire core conductor is extruded with a ground wire core insulating sleeve. The outer sides of the ground wire cores are sleeved with supporting frames. The three power wire cores are arranged between the supporting frames respectively. Cable cores are effectively fixed and supported by adopting the spirally arranged supporting frames, so that the mutual extrusion deformation among the cable cores is avoided. The structural strength, the ductility, the tear resistance and the like of the cable core of the scandium aluminum alloy conductor low-voltage rubber jacketedflexible cable are effectively improved. The defect that a traditional cable is poor in bending performance is overcome. The scandium aluminum alloy conductor low-voltage rubber jacketed flexible cable is effectively suitable for a low-voltage cable and is convenient to popularize for a long period of time.

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 scandium aluminum alloy conductor for offshore wind power generation. Background technique [0002] With the continuous development of China's industry and the rapid development of wind power generation, the use of cables 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 are insulation, sheath and conductor. The main component of the conductor for manufacturing cables is copper, which accounts for about 70% of the total copper consumption in the production industry. With the exhaustion of China’s copper resources, China’s copper resources are very scarce. 80% need to be imported, which is highly dependent; therefore, as the price of copper continues to rise, replaci...
