The wire Chip referred to is called type SO cable.  It is really 
expensive (when you hear the price per foot you'll probably say 
SOB!),  but it is the best for making the main AC power cord for any 
portable electrical equipment that needs a power cord with a plug on 
the end, including a powerful, pole pig driven TC system.  The most flexible
cable you can probably get (because the thousands of individual strands are very
small guage for extra flexibility) is single conductor, neoprene covered standard 
welding cable.  It is available in small guages like #6 and #4 AWG up 
to much larger guages like #000.  I use #000 welding cable for my 
system tether to RF ground with no complaints.  This seems to be 
acceptable up to a 50 foot straight run at 10 kVA  system power, 
probably more. It is not uncommon in the electrical power industry to tape 3 or
4 of these into a cable with electrical tape every foot or so.  Welding 
cable also makes excellent cable for the primary circuit interconnect 
wire, especially the flying tap lead for the primary.
