Abstract

The invention relates to a manufacturing method for a novel aluminium alloy cable. The method comprises the following main manufacturing steps of: drawing single wires; stranding wire cores; performing heat treatment on the wire cores; performing resistance detection on conductors; extruding insulating layers; crosslinking the insulating layers; performing an insulating hot-prolongation test; performing insulating spark verification; stranding the wire cores into a cable, filling, and lapping an isolating layer; extruding a metal protecting sleeve; cooling the metal protecting sleeve; performing flaw detection on the metal protecting sleeve; embossing the metal protecting sleeve; extruding a non-metal outer protecting sleeve; and performing spark verification on an outer protecting layer. The novel aluminium alloy cable manufactured by adopting the method disclosed by the invention is excellent in flexible performance, conductive performance, low-temperature-resistant performance, heat-resistant performance and mechanical performance, and much superior to common aluminium alloy cables in current-carrying capability, fireproof performance and waterproof performance.

Description

technical field [0001] The invention relates to the technical field of special cables, in particular to a method for manufacturing a novel aluminum alloy cable. Background technique [0002] In the past two decades, the cables used in public places and high-rise buildings in my country have basically been low-smoke low-halogen or low-smoke halogen-free flame-retardant cables with copper core conductors. However, copper resources are in short supply in my country, and 70% of them come from imports. Copper prices have remained high since 2005. my country's aluminum resources are very rich, but ordinary electrical aluminum has poor creep resistance and elongation properties, resulting in poor operating safety during cable operation, so there are few power cables using aluminum as conductive cores in my country. As the production technology of 8000 series aluminum alloy materials continues to mature in my country, it is possible to use 8000 series aluminum alloys as conducto...
