Embodiment Construction
[0053] for figure 1 The copper-clad aluminum five-core circular flame-retardant and fire-resistant flexible cable of the present invention shown, the method for manufacturing the cable includes: the step of making the copper-clad aluminum wire into a single conductive core 1; A step of forming a wire core refractory layer (2, 3) on the outer surface; an insulation treatment step of extruding an insulating material on the wire core refractory layer (2, 3) to form an insulated wire core with an insulating layer 4; Carrying out cabling treatment on the insulated wire core with the insulating layer 4 to form a cable; and extruding refractory plastic on the cable to form a flame-retardant sheath layer 6 . Since the cross-section of the single conductive core 1 is usually circular when manufacturing a single conductive core 1, it is usually not necessary to process the conductive core 1 into a circular conductive core 1. ; But if the cross-section of the single conductive wire core...
