EE/F-S 2.6 V2

Ultimate 2.6mm solid core in-wall AC power cable with 102SSC


Dedicated wiring between the power distribution board and the audio room, "audio-dedicated in-wall AC power wiring," is the goal of audiophiles who are particular about power supplies, and it is one of the points of achievement.

It is no exaggeration to say that the history of "audio-dedicated in-wall AC power wiring" was paved by Oyaide Electric's EE/F-S 2.6. The overwhelming performance of this cable exceeded the expectations of audiophiles with its strong enthusiasm, and it has continued to reign as the reference for "audio-dedicated in-wall AC power wiring" ever since.

"EE/F-S 2.6", which was even described as "the best power cable ever", will regrettably be discontinued along with its younger brother "EE/F-S 2.0" due to the end of supply of PCOCC-A conductor.

However, there have been many requests for the revival of "EE/F-S 2.0" and "EE/F-S 2.6". In 2015, Nine years after the debut of the first generation, the "EE/F-S 2.6 V2" was introduced using the 102 SSC precision conductor to meet these expectations. The overwhelming presence of this cable is enough to renew the fundamental power of audio reproduction from the bottom up, and there are rare cables that appeal to the enthusiasm of audiophiles as much as this.

It is truly an audio-only in-wall AC power wiring that plays the forbidden ground, which only those who have used it can enjoy.


"102 SSC" - Oyaide Electric Precision Conductor

  • To avoid impurities as much as possible, only virgin copper that does not contain any recycled copper is used in accordance with JIS C1011.
  • Peeling process is applied to remove 100% of impurities attached to the surface.
  • In order to facilitate the flow of electrical signals through the surface layer of the conductor, the strand is made finer using a natural diamond die to improve the surface smoothness of the strand.
  • Two annealing processes are used to eliminate mechanical stress distortions in the strands.
  • Thorough product control of manufacturing control values, maintenance, shipping days, etc. Achieved the highest conductivity of 102.3% IACS.

3 Core 2.6mm Solid Core Wire Configuration for Various Situations

The conductor diameter is 2.6mm (≈10AWG) solid core wire, which can be said to be over-spec for in-wall AC power wiring, and the three-core configuration can be used in various situations.

Since 102SSC is used for all three cores, a wide range of needs can be met, from single-layer 100 V to single-phase 200 V and three-phase 200 V, depending on the customer's needs.

The insulation coating is color-coded red/white/black under the JIS standards, as used for 3 core in-wall AC power wiring, so that electricians can wire without any confusion.

600V/30A Compatible with a Generous Response

The conductor is insulated with polyethylene, which has excellent electrical characteristics. Polyethylene has an extremely low dielectric constant of 1/4 compared to ordinary PVC insulation, reducing transmission loss. This contributes to less muddy reproduced sound.

This excellent insulation property and the relative cross-sectional area of a 2.6mm single wire (equivalent to 5.3sq) provide high-power transmission with a withstand voltage of 600V maximum 30 Amps and an aggressive response.

Thick Copper Foil Shield Provides over 30dB Noise Immunity

The EE/F-S 2.6 V2 is equipped with an extremely robust 0.1mm-thick copper foil shield that is truly over-spec.

Thanks to this copper foil, which is wrapped around without gaps and boasts a 100% shielding ratio, "EE/F-S 2.6 V2" exhibits 30dB more noise immunity than ordinary unshielded parallel wires.

A drain wire (30/0.18) of sufficient thickness is placed on the copper foil shield to provide a grounding wire. The copper foil shield can also be easily grounded to earth ground.

In addition, polypropylene tape is used for the internal intervention that fills the gap between the conductor and the copper foil shield, and we have done our best to improve the electrical characteristics and strength of the conductor.

EE/F-S 2.6 was designed on the assumption that it could be used under several circumstances such as in a home, a broadcast station, or a professional studio. Because of its copper foil shielding, it provides clean power without being affected by noise. The copper foil shielding has demonstrated 30dB superiority in noise protection over standard in wall wiring. Moreover, in order to connect easily to a terminal, 0.75sq drain wire is built into EE/F-S 2.6.

Halogen-free PE Cable Sheath with Excellent Toughness and Vibration-damping Properties

Oyaide's halogen-free sheath, which is a characteristic of Oyaide cables in the 21st century, has had a positive impact on the quality of reproduction.

The clear, unobstructed reproduction capability that cannot be achieved with conventional PVC sheaths, combined with the polyethylene insulation mentioned above, makes it an indispensable material for Oyaide's audio cables.

Please enjoy the quality sound of a new generation woven by the trinity of 102 SSC conductor, polyethylene insulation, and halogen-free sheath.
