Copper Stranded/Bunched

Copper stranded (bunched) is a flexible conductor made by twisting multiple pure drawn copper wires together. It is an essential conductive material for flexible cable production — required where high bending performance must be combined with stable conductivity.

LiOA Copper manufactures stranded copper from in-house 99.99% pure drawn wire, conforming to international standard IEC 60228 (Class 5, Class 6). The product is packaged on reusable Techno reels — replacing traditional wooden drums entirely.
