PCOCC-A
PCOCC copper is a material that includes very few impurities and insures very low levels of signal disturbance. 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 μ 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.
Triple-layered shielding
We have advocated the importance of noise protection which becomes a defining feature of power cable. Although we accomplished certain results by applying star-quad shielding structure to L/i 50 series, considering customer demands and trends, we pursued producing updated product with a state-of-art technology. For TUNAMI, we developed triple-layered shielding structure.
The first layer of this structure converts electromagnetic wave into thermal energy by interfusing electromagnetic insulator. As the second layer, semiconductor layer (carbon) is employed for its characteristic that discharges static electricity without affecting its conductor. A copper foil shielding is set as the third layer to protect the conductor from external noise. Furthermore, drain wires, closely-situated to copper foil shield, make S/N ratio higher by connecting to earth ground.
Insulator
After the deep analysis for insulator, we selected polymer polyolefin that has different degree of hardness at interior and exterior to prevent negative effect by sympathetic vibration. Moreover, this material has a quarter of permittivity compared to common PVC and we paid careful attention to strengthen the cohesiveness of its insulator and conductor in order to infill random space and maintain a high-quality signal transmission.
端末コネクター（TUNAMI GPX）
The plug and connector, P/C-046Re, is specifically arranged for TUNAMI GPX. In addition to alteration of plating thickness, its Italian-Red outer barrel is the perfect expression of passionate sound of TUNAMI GPX.
