Abstract
The utility model discloses an aluminium alloy pre-branching cable which comprises a main cable and a branch cable separated from the main cable. A coupling piece sleeves the branch of the main cable and the branch cable. Two layers of the coupling piece are arranged: the inner layer is an aluminium alloy layer and the outer layer is a reinforced layer. The coupling piece is successively wrapped with a mica tape, an electric tape and a waterproof tape. A branch insulation part is injection molded at the branch of the main cable and the branch cable. The coupling piece is positioned inside the branch insulation part. In comparison with present cables, the aluminium alloy pre-branching cable provided by the utility model has advantages as follows: costs of the aluminium alloy pre-branching cable with adoption of a conductor aluminium alloy material are about 40% lower than that of a cable with adoption of a copper core; the aluminium alloy pre-branching cable is light in weight, is convenient to install, has good effects of waterproofness, fire resistance and corrosion resistance, and has long practical life; and by the adoption of a low-smoke, halogen-free, flame-retardant polyolefin material, the cable provided by the utility model is green, environmentally friendly and pollution-free.
