Abstract
The invention relates to a non-halogen inflame-retardant crosslink copper-clad aluminum wire and the preparing method thereof. The method comprises the steps of: cladding a layer of copper foil on the external surface of the aluminum wire as the internal conductor of the wire, using an insulating material made of non-halogen inflame-retardant polyolefine as the external insulating layer, producing wire by a wire extruder, and radiation crosslinking by an electronic accelerator. Since the aluminum is cheaper than copper, and the non-halogen inflame-retardant formulation and radiation crosslinking method are used, the produced copper-clad aluminum wire has the advantages of copper wire, is light, bending-resistant and tear-resistant, and is particularly for indoor wire.
