ESOTERIC Stressfree Power Cords

The engineering design of ‘MEXCEL’ conductors is to reduce skin effect. Skin effect is the tendency of an AC signal to travel near the surface of a conductor and cause the resistance of the conductor to increase with the frequency of the current.

‘MEXCEL’ conductors are made from a number of separately-insulated wire strands, specially twisted together to increase the surface area of conduction. This design greatly reduces the skin effect and lowers high frequency resistance, resulting in flat impedance response over the entire frequency range. Thanks to extended frequency and flat impedance response, the 7N-PC9500MEXCEL delivers ultimately pure AC power to the system.

Pure conductor / Stressfree annealing technology

ESOTERIC power cords incorporate high purity "Stressfree" copper conductors. The material purity of conductors used for critical areas is 7N (99.99999%) copper. This high purity material was originally developed for the semiconductor industry which requires an extremely high level of quality certification, and guarantees 7N purity with less-than-0.01 ppm (parts per million), of metallic impurities. This quality level is maintained by using ‘GD-Ms’ high precision material analysis technology. The high purity copper wire uses special "Stressfree" annealing technology to minimize distortion of the crystalline structure of the copper. These new power cords also feature extra-large crystalline structure conductor technology, "D.U.C.C." (Dia Ultra Crystallized Copper) in order to farther optimize the high purity and conductivity of the power path.

- 7N Cu multi-strand core conductor (x2)
- 4.5 N Cu multi-strand ground line (x1)
- Polyurethane coat 4N Cu braid + semi-conductive carbon tape shielding
- Low dielectric polyolefin-hybrid insulation
(polyolefin + tungsten, amorphous and carbon powder)
- Ultimate quality power plug / IEC connector
- Heavy weight aluminum + Carbon fabric connector sleeve

The 7N-PC9500MEXCEL is an upgraded version of the 7N-PC9300MEXCEL and incorporates a newly designed IEC / Wall plug. This plug set features our highest quality silver + rhodium plated beryllium copper contact elements for ultimate conductivity and high mechanical strength that can withstand an 8 kg load. In order to control micro resonance, connector sleeves are precisely machined from solid aluminum and are quite heavy. Carbon fabric sleeves are attached to reject RF noise from entering the electric power path. The cable incorporates high purity, D.U.C.C. (Dia Ultra Crystallized Copper) 7N Cu "MEXCEL" conductor produced by our Stressfree annealing technology. Polymeric polyolefin-hybrid insulation (made from polyolefin + tungsten, amorphous and carbon powder), provides an extremely low dielectric and high noise absorption capability. The outer jacket is made of UV resistant polyurethane to protect the cable form chemical and mechanical aging.
