RE: cable has direction if and only if ground/shield/drain are assymetrical

While that may be an overiding concern, all cables have a direction simply because of the mechanical nature of drawing wire. Most wire is mechanically drawn, whereby a copper ingot is pulled through a series of dies, which "pulls" the wire down to the desired size. This actually mechanically forces the crystalline structure to run in a certain direction, since you are forcing the wire through a funnel shaped die.

Even with sheet metal, you can see evidence of such a grain structure. Bending or flanging in one direction is easier than in the other, with bending with the grain often leading to the metal fracturing, particularly with thicker sheet. (Ask any experienced sheet metal worker, I worked in the field for over a decade).

Machinists will also tell you that because of the drawing process, the middle section of a round stock is not as desirable as the outer surfaces, preferring to machine down pieces which are most closely dimensioned to the final finished dimension (of course it saves time, too).

IIRC, Harmonic Tech and Acoustic Zen have a means of hot rolling the wire to finished dimensions and thus eliminating the mechanical effect of drawing wire.

Of course YMMV,

This is also most likely why direction of a fuse matters. - carcass93 06:59:13 04/14/12 (0)
