WRK-500/1+6 Tubular Stranding Machine for 7-Wire ACSR and Copper Conductors The WRK-500/1+6 Tubular Stranding Machine is designed for stranding 7-wire steel-cored aluminum conductors (ACSR) and copper conductors. It uses a 1+6 stranding configuration, with one central wire surrounded by six outer wires to form a compact stranded conductor. For manufacturers producing power conductors and copper stranded wires, this machine provides a practical solution for combining
