REDGUM OCC Pure Silver Interconnect

OCC Pure Copper and OCC Pure Silver have been considered the state-of-the-art conductor materials in the world. Due to the rapid development of the electronics industry, traditional audio and video systems marched into the era of Hi-Fidelity and Hi-Resolution. Hence, it was to be an inevitable trend to upgrade the quality of cables working as signal transmitters.

The world patented “UP-OCC” (Ultra Pure Copper by Ohno Continuous Casting Process) was developed by Professor Ohno of Chiba Institute of Technology in Japan. This technology has been applied to the manufacturing of single crystallized copper with the process of heated mould continuous casting, and the resulting product, OCC Pure Copper, has reached the purity of 99.998%, or even higher than 99.9999%. OCC Pure Silver is created by the same process.

Because of its characteristics of single crystal, unidirectional, free of impurity, flexible fatigue-resistance, corrosive-resistance, low electric resistance, none-crystal boundaries, rapid transmissibility, perfect in structure, and easy to process, together these all make OCC Pure Copper or Silver an ideal material for making rapid transmission lines. From internal hook-up wires to interconnect cables, they can be widely applied to hi-tech products such as Hi-Fi Stereo and Home Theatre systems, Hi Resolution TV, etc.
