Abstract
Disclosed is a novel rectangular insulation aluminum stranded wire for a reactor. The insulation aluminum stranded wire comprises conductors 1, a conductive insulation layer 2 and a composite insulation layer 3, and is characterized in that the conductive insulation layer is wrapped around the conductors to form insulated conductors, a plurality of the insulated conductors are stranded and then pressed to form a rectangular insulation conductor, and the composite insulation layer is wrapped around the outer layer of the rectangular insulation conductor. In addition, the conductive insulation layer is made of polyester films or polyimide films, and the composite insulation layer is made by combining the polyimide films, the polyester films, aromatic polyamide fiber papers and the polyimide films. Under the condition of ultra-high voltage operation, the insulation aluminum stranded wire can reduce eddy current loss and harmonic impedance of winding wires, has the performances of low loss, high-temperature resistance, ultra-high voltage resistance and the like owning to the selection of insulation materials, and is capable of meeting performance demands of the winding wires for the ultra-high voltage reactor and providing an entirely novel product for the manufacturing field of electric conductors and cables.
