Construction
Bare stranded soft-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
It is used in overhead electrical transmission and distribution, for grounding electrical systems where high conductivity and flexibility is required. Suitable for numerous other applications.
Applicable Standard
IEC 60228
