why?Can anynone explain to me?

twisted pairs are often used to carry differential signals. in this case, any stray varying magnetic fields will tend to induce a current equally in both conductors. This equal current will then be rejected at the receiving end - provided the CMRR (common mode rejection ratio) is sufficiently high. The twist is there to help ensure each wire gets the same amount of magnetic flux ...

there ara two kind of wires,which is more fit for Braiding Cables ?

1,ten thin copper wires composed one strand
2,one single copper wires

the diameter is same.

I mean the speaker wires!

flexible is easier mechanically.

I'd be most concerned with the electrical properties for use either in interconnects or speaker cables...

Hi,
Check out "the naked truth about speaker-cables". Google it and it will come up.

Multi-strand wire is much easier to braid with especially when braiding more than 4 wires. You can braid solid core, but the fewer number of wires, the better. We braid 10 multi-stranded conductors. Take a look in the Vendors Bazaar.
