Twisted power cable is a normal item available from most all
electrical and electronic suppliers. Most often it will be a high flex

In the Allied 2007 catalog on page 439 is igus Chainflex Continuous

You can also get the twisted cable with shield if you like.
The shield does only a little and the twist does a lot to reduce interferance.
