FIELD: cable making. SUBSTANCE: etching solution presenting solution of sulfuric acid with concentration 5.0 - 14.0 %, neutralization solution presenting soap and alkaline solution with alkalinity 0.03-0.2 % is prepared and etching of wire is conducted at temperature 35-70 C of etching solution in the course of 10-30 min. Neutralization of acid is performed at temperature 70-80 C of neutralization solution. After this wire is drawn and annealed. EFFECT: enhanced productivity of process. 1 dwg
