The copper of PA-02 V2 is the Oyaide Elec. proprietary 102SSC with its incredible conductivity level of 102.3% IACS (after annealing process). The copper base material for 102 SSC is refined in Japan and conforms to the elite Japanese JIS C1011
industrial standard with only pure virgin copper base (no recycled material).

The PA-02 V2 series also employs mechanical peeling – a precisely controlled process that removes 100% of impurities. Oyaide also made use of natural diamond dies over synthetic diamond dies, yielding more uniform volume reduction with reduced stress and improved lubricity.

The 102SSC wire surface structure is far superior to all others, with its 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). 3E 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.
