True Purity of the 7N-P4030 II Various manufacturers claim to produce ultra high purity, 7N (99.99999%) copper. However, different refining processes yield materials that vary greatly in both the composition of impurities and crystalline structure. Most of the "so called" 6N and 7N materials are not measured comprehensively. Glow Discharge Mass Spectrometry - an extremely powerful tool for performing ultra-trace elemental analysis has been applied to pure copper used in the Acrolink 7N-P4030 II ac power cable. The results in the accompanying table demonstrate that Acrolink has achieved an unrivalled standard of purity. The Effect of Impurities Minute impurities create variations in impedance, inhibiting he ability of a cable to achieve extended frequency response. Responsible for meeting the needs of leading edge computer and aerospace technology, Acrolink has developed a multi-stage process that removes each impurity individually. Applying this to audio they have been able to achieve flat frequency response to 18 GHz in their Mexcel series! Stress-Free After the cable core is formed, the Acrolink Stress-Free process is applied to the 7N-P4030 in a clean, oxygen free environment. This imparts permanent self-annealing properties: No matter how often the cable is bent or impacted, it will always return to its original relaxed state (uniform crystalline structure). Dielectric A new polymer polyolefin, presently the best material available, has been chosen for the insulator of the Acrolink 7N-P4030, for its extremely low dielectric constant. Resonance Absorption Proper absorption of resonance is one of the key factors in determining final sound quality. Acrolink has focused on this issue for many years and developed tremendous expertise. Materials are carefully selected for each individual design in order to achieve perfectly balanced and effective absorption. A new polymer polyolefin, tungsten powder, and an amorphus powder has been chosen for the inner sheethe of the Acrolink 7N-P4030, for excellent vibration absorption. The outer jacket also utilizes a polyolefin material for excellent flexibility and vibration characteristics. 7N-P4030 Specifications Conductors: 7N Copper, 0.26mm X 100 strands X 2 (red and black); Ground: 4N5 copper 0.26mm X 100 strands X 1 (green) |
