NRG-Y3 cables use direction-controlled Long-Grain-Copper strands in a Semi-Solid Concentric conductor arrangement in which strands are packed more tightly and never change position within the bundle. This construction significantly reduces strand interaction distortion. The greater purity and less complicated grain structure within LGC copper further reduces distortion. In addition, NRG-Y3s direction-controlled Silver-Plated shield conductors efficiently drain RF noise from the line and neutral shields to ground via the third ground pin. The net result is powerful, dynamic and immersive!
