Furutech has announced the release of their limited edition ultra-high-end performance DPS-4 power cable (off-the-reel); consisting of a revolutionary new copper technology called α (Alpha) OCC‐DUCC.

Alpha OCC-DUCC is constructed using a combination of DUCC (Dia Ultra Crystallized Copper) and Furutech’s world-famous Pure Transmission α (Alpha) OCC (Ohno Continuous Casting) copper.

Furutech α OCC-DUCC – supplied and regulated with strict quality control by Mitsubishi Materials Industries (MMI) – is one of the best conductors Furutech engineers have found for signal transmission and sound reproduction. MMI is the leading manufacturer of the highest-purity oxygen-free copper in the world. MMI processes this extremely pure oxygen-free copper with a new technology that optimally aligns the crystals while reducing the number of crystal-grain boundaries, resulting in a tremendously efficient conductor.

Other ultra-pure copper cable types, for example OFC (Oxygen-Free Copper) and PCOCC (Perfect Crystal Ohno Continuous Casting), are about maximizing the length of the crystals in one dimension and improving the purity of the conductor to eliminate the so-called “diode distortion” generated during a signal's transition between neighboring crystals. Straight OCC copper benefits are thus its larger “fibrous” crystals and creating as few crystal junctions as possible. OCC copper is however sensitive to directionality, i.e. one path exhibits the least resistance. Furutech’s world famous Pure Transmission α-OCC is the result of further processing of OCC with their Alpha Super Cryogenic and Demagnetizing treatment.

MMI's research has however shown that impurities still arise inside the crystals of OCC copper; and not just at the contact areas. Their DUCC process goes a significant step further and involves re-crystallization of the copper during which pollutants are released and removed. MMI has thus managed to design their new DUCC conductor to optimally align the copper crystal grain structure in addition to reducing crystal grain boundaries. As a result, DUCC copper is less sensitive to directionality than OCC and also far more superior.

The design of the DPS-4 power cable is intriguingly sophisticated:

Each of its three cores is constructed of three layers of conductors - wires, differing in number, direction of winding and material they are made of. The inner bundle consists of 79 Alpha-OCC wires with a 0.18 mm2 gauge each, twisted to the right. The next layer is wound onto it, made of 37 DUCC (7N) wires with a 0.18 mm2 gauge each and twisted left; and finally on top of these two, there is another core with 42 DUCC (7N) copper wires with a 0.18 mm2 gauge each and twisted to the right. The final bundle has a diameter of 2.75 mm2. The overall cable diameter is 17mm.





The limited edition DPS-4 power cable should be terminated with Furutech’s highest quality FI-50 NCF power plugs for optimum performance (see below).
