QED is proud to introduce the QED XT3 Power Cable, the latest in a new generation of audiophile power cables intended to complement its award-winning range of speaker cables and audio interconnects.
X-Tube technology
QED XT3 power cables feature a specially adapted version of X-Tube Technology similar to our speaker cables but specifically tuned to be appropriate for this new application. The braided individual cores in the live and neutral conductors are small enough that they are not affected by the eddy currents from adjacent cores which help contribute to the proximity effect.
Because they are effectively isolated from one another, the carefully calculated twist rate of the strands means that no two conductors remain next to each other in the parallel configuration for more than a few millimetres. This further enhances the even current flow along the cable at all frequencies.
The separate bundles have individual insulation using K130 PVC to control cable capacitance while providing the level of electrical isolation demanded by international safety standards. The whole arrangement has a hollow LDPE core to control cable inductance.
In this way, the cable parameters do not alter the correct phase relationship between voltage and current, further decreasing distortion compared to an ordinary power cable.
Complete practicality
XT3 is as thin and flexible, and thus practical, as possible. Only the live and neutral cores have the X-Tube treatment – the earth core uses conventional geometry.
And because X-Tube geometry enables the whole cross-sectional area of the cable to keep to a tidy 1.5 mm sq, XT3 is supremely flexible and usefully slim despite its audiophile potential.
