Abstract

The invention provides a copper strip for a long cable, which has the advantages of high conductivity and high extension properties and can effectively reduce the cost, and a production method. The technical scheme is that the copper strip for the long cable is characterized by being formed by following components in weight percentage of: 99.945-99.975% of copper, 0.0008-0.0050% of phosphorus, less than 0.0025% of impurity O, less than 0.0045% of Fe and less than 0.035% of the total sum of impurities. The production method of the copper strip for the long cable is characterized by comprising the following steps of: preparing materials, smelting, covering, deoxidizing, detecting, carrying out upward continuous casting, detecting components of a strip blank, sizing and coiling, milling a surface, roughly rolling, cutting edges, carrying out intermediate annealing, brushing, finely rolling, carrying out finished-product annealing, washing and passivating the surface, cutting a finished product, packaging and storing.
