Product Code: GB-3X21M
Diameter: OD10mm
Length: 1.2 meters  1.5 meters ,  2.0 meters, 3 meters, 5 meters
Material: 4N OFC 
Overload protection: support 1A-10A safe replacement (default 3A fuse)
Material: 99.998% copper wire, 2 square * 3 core with aluminum foil and copper mesh sets of shielding, insulation layer Fulong plating process resistance to high and low temperature (-65 ℃ ~ 200 ℃) burning does not melt, hot not bad.
Performance: can effectively help high-end audio equipment filter power input noise source, resistance to external secondary signal interference. So that the use of high-end audio equipment reduce lower noise.
Note: In different products use, the effect is also different. The product can not be intuitively reflected, the product can not be used as a signal filter equipment. N4 power cord better than the ordinary power line performance, anti-interference ability.

                                         OCC and OFC
 
      UP-OCC uses technology (Ultra Pure Coppe.r by Ohno Continuous Casting Process) manufactured single crystal
oxygen-free copper, non-directional, high purity, corrosion, low electrical impedance makes the wire for high-speed 
signal transmission quality. Production of single crystal copper (referred OCC) wire for sound, is a major breakthrough 
in recent years, audio wire manufacturing. Scientific evidence: a high-purity single-crystal copper OFC, its whole
root of copper rod composed of only one grain, does not exist between the grains produced "grain boundaries",
a variety of audio and video signal during transmission by the time the grain boundary will produce reflection, refraction,
and so the signal distortion, attenuation distortion, and single-crystal copper little or no grain boundaries grain 
boundaries so fundamentally improved transmission quality, which has a very high signal transmission performance.
Single crystal copper (OCC) copper casting techniques drawn only by a grain composition, with exceptional machining 
performance and electrical characteristics. Its characteristics are:
 1. crystal purity of 99.9999% copper;
 2. resistance of 8% to 13% lower than the average copper;
 3. high toughness, ordinary copper reverse lap 16 that is broken, single-crystal copper can reverse the 116 laps.
Compared with the OCC, is widely used in the production of oxygen-free copper wire rod sound (the OFC), the English name 
of the oxygen-free copper referred OFC: purity of 99.995% copper. A large number of its internal grain "grain boundaries" 
cause signal distortion and attenuation, as well as signal transmission performance compares favorably with single crystal 
copper (OCC).
