PCOCC-A PCOCC copper is a material that has very little impurities, ensuring very low levels of signal disturbances. Because of its low incidence of grain boundaries, the signal passes without impediment or distortion. Heating and cooling the PCOCC wire under controlled circumstances yields a densely re-crystallized, highly pure structure called a mu conductor. The resulting product with a mirror finish applied is called PCOCC-A copper. This highly advanced product is made possible by the combined application of high technology and traditional Japanese craftsmanship.		Japan Made. Highest manufacturing standard Contents ..

Cross insulated stabilizer CIS structure Oyaide have continuously aim at increasing the vibration damping property and noise protection capability. ACROSS 900 elevates interconnect cable to new heights by applying CIS (Cross Insulated Stabilizer) structure developed specially for ACROSS series. Since the CIS structure supports the central conductor not with surface but point, it is able to minimize mutual interference between the central conductor and the outside. And internally built vibration damper diffuses vibrations into the air chamber rather than being re-absorbed into the cable structure and passed along with the signal as distortion. The incomparable advancement of vibration control properties and superior electrical characteristics achieves excellent performance without any loss of transmission. Multi-stranded wire A core component of ACROSS 900 is the PCOCC-A signal transmission , 0.78sq diameter, and forms Multi-stranded wire structure which was originally invented for ACROSS series and reflects our solid design concept. Rather than twisting whole wires, the four-layered inverted concentric structure is employed for maximum density and uniformity of wire structure and for infilling of internal space and preventing deformation among the wires. Spiral shielding is applied to infill internal space and to prevent deformation among the wires as well as the conductor. The number of wires used for the spiral shield is about three times more than the number for the conductor.
