Two-Pair 22AWG Individual Shield: Plenum - 22EPS2IP. Two-pair shielded plenum rated cable for balanced audio, data or control applications. Each conductor is made from 22AWG tinned copper for low DCR, corrosion resistance and improved solder adhesion. The conductors are insulated with a polypropylene dielectric that has lower capacitance and a higher melt temperature for reduced wick-back when soldering. By Clark Wire & Cable.
