IsoTek EVO3 Optimum Power CableAt the Optimums core are three silver plated Ohno Continuous Cast (OCC) copper conductors, with each conductor strand being of a square configuration for tighter bunching. The OCC offers a vastly superior level of purity with outstanding electrical conductivity, improved flexibility, resistance to fatigue and corrosion. A high quality FEP provides a very low dielectric constant over a wide frequency range. The three conductors are given a slight
