Construction Bare stranded hard-drawn copper conductor is a concentric-lay-stranded conductor consisting of hard-drawn copper wires available in both single layer and multi-layer constructions. Application Bare stranded hard-drawn copper conductor is suitable for overhead transmission and distribution networks applications, where the highest electrical conductivity per unit area and good strength-to-weight ratio are required. Applicable Standard Bare stranded hard-drawn copper conductor can be supplied to meet various International Standards as follows: DIN 48201 / 1 Dimension Characteristics Nominal Cross
