NFPA 79 and UL approved torsion cables

[mccrh]

I have a special application that is requiring a torsion cable. At least, 90 degree's per .8m. Unfortunately, we are an Industrial Machine Manufacturer and have to comply with NFPA 79. I need an UL approved and listed torsion rated cable. Per NFPA 79, we can not use any AWM style cables on our machines. This seems to be the problem I am having while researching torsion cables, they all seem to be UL AWM approved. Would like to know if there is any other UL approval for torsion cables and suggestions that will conform to NFPA 79 and UL listed?
