Abstract

The invention discloses an alloy copper cable core with low resistance and a manufacturing method thereof. The cable core is characterized by being prepared from, by weight, 10-12% of nickel, 5-8% ofzirconium, 3-5% of magnesium, 2-3% of graphite powder, 8-12% of zinc, 4-6% of barium metaborate, 1-2% of cobalt, 0.5-0.8% of sodium zirconate, 1.1-1.5% of manganese, 0.8-1.2% of carbon, 2-4% of anti-aging agents, 1-1.5% of antimony, 1-1.2% of aluminum, 0.6-0.8% of lithium and the balance copper. According to the alloy copper cable core with low resistance and the manufacturing method thereof, copper, nickel and zirconium are adopted as main alloy alloy materials, carbon, manganese, antimony and other elements are fused, and the manufactured alloy copper cable core has the good actual effects of being good in strength, high in tenacity, low in resistance, good in conductive effect, small in generated heat and the like.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a small resistance alloy copper cable core and a manufacturing method thereof. Background technique [0002] At present, in the manufacturing and processing of cable copper core, a single alloy copper is used. The produced cable has high resistance. In the process of actual power transmission, the power has a large loss, resulting in a huge waste of resources. The toughness of cable copper core Poor, after a long time of use, the cable sags a lot, if the cable is under the farmland or a gathering place of residents, there is a great potential safety hazard.
