The copper of PA-02 V2 is 102SSC which produced by Oyaide Elec. It shows an incredible conductivity level of 102.3% IACS (after annealing process).
The copper base material for 102 SSC is refined in Japan and conform to the elite Japanese JIS C1011
industrial standard. Only pure virgin copper base we specified that does not contain any recycled
material. Also, we have instead employed mechanical peeling – a very precisely controlled process that removes 100% of impurities and we picked the use of natural diamond dies over synthetic diamond
dies which yield more uniform volume reduction with reduced stress and improved lubricity.
102SSC wire whose surface structure is far superior to all others.With outer diameter accuracy of ±1μm far exceeding the ±0.8μm in Japanese standards for conventional copper wires.
The conductor structure of PA-02 V2 is 3 element stranding. 3E stranding combines strands of three different diameters to increase the density of the wire by decreasing the spaces between strands. This results in a smaller outer diameter than the same gauge wire made with identical individual strands, plus a more accurate,
stable and perfectly circular cross section.
