Abstract
The invention relates to a voltage-withstanding aluminum alloy cable. The voltage-withstanding aluminum alloy cable comprises aluminum alloy wires, a supporting part, quartz filler, elastic ribs, a shielding layer, a reinforced braided layer, a flame-retardant layer, an insulating layer and an outer sheath layer. The aluminum alloy wires are arranged on the outer surface of the supporting part in a wound mode to form a cable core. The cable core is covered with the insulating layer, the space between the insulating layer and the cable core is filled with the quartz filler, and the shielding layer, the reinforced braided layer, the flame-retardant layer and the outer sheath layer are sequentially arranged outside the insulating layer. The elastic ribs are uniformly arranged in the outer sheath layer, and therefore the cable can withstand a higher voltage. The internal aluminum alloy wires are uniformly arranged on the outer surface of the supporting part in the wound mode, and therefore deformation of the cable core is effectively prevented. Meanwhile, wear-resisting and voltage-withstanding rubber is adopted as the outer sheath layer of the cable, and therefore the cable is better in voltage-withstanding performance, aging resistance, oil resistance and water resistance, safer and more practical.
