Abstract

PURPOSE: To form a hydrophilic layer on the surface of Al stranded wire layers in a short time by forming two or more Al stranded wire layers on a steel core, and heating the Al stranded wire layers through high-frequency heating to specific temperatures then roughening the surface by a chemical method.
CONSTITUTION: Two or more Al stranded layers are formed on a steel core by a wire twisting machine 2 and this steel-cored Al stranded wire 1 is passed through the inside of the heating coil 7 of a high-frequency heater 5, whereby the Al stranded wire layers are heated to 50W150°C. It is introduced into a chemical surface roughening treatment tank 6, where it is passed through an alkaline soln. such as NaOH soln. of 1.5W5% concentrations or an acidic soln., whereby the surface of the Al stranded wire layers is roughened is made phydrophilic. The generation of corona is prevented without spheroidizing of the moisture stuck on the steel-cored Al stranded wire.
