NEOTECH NEI-3003 III

Coaxial signal cable by the metre. 99.99998% pure UP-OCC copper conductors mixed with silver-plated UP-OCC strands, double-shielded.

Here sold by the metre. It is supplied in a single piece of the quantity ordered in multiples of 1 metre or 50cm

The Neotech NEI-3003 MKIII interconnect cable is of the coaxial type. The double layer of polyethylene and polyethylene foam insulates the OCC copper conductor to minimise signal loss. The double shielding of conductive PVC and braided OFC copper ensures sophisticated and correct sound performance.

What is UP-OCC?
The UP OCC process for refining copper was developed and patented by Professor Ohno of the Chiba Institute of Technology in Japan. This manufacturing process is incredibly popular for the production of wires and cables for the audio/video industry.
UP OCC stands for Ultra-Pure, Ohno Continuous Casting. In conventional processing, hot molten copper is poured into a cooled die for extrusion, resulting in a multiple, fractional crystal structure. Oxygen-free copper (OFC) has undesirable effects that lead many to use more expensive materials such as silver. The OCC process uses a heated mould for casting and extrusion, with cooling in a separate process. The result is a larger crystal size and higher purity, around 6N, 99.9998%! Looked at another way, traditional copper has oxygen impurities of 200 to 500 parts per million (PPM), whereas in traditional OFC copper this is reduced to less than 10 ppm. With the OCC process, this figure is halved to less than 5 PPM of oxygen and less than 0.25 PPM of hydrogen (compared to 0.5 PPM for OFC). With these results, the OCC process creates an ‘ultra-pure’ copper
