Re: Do the Twist?

John,

I'd twist the wires, but I will be interested in what others have to
say on this topic.

It might be worth a call to olflex, a manufacturer of motor control
cabling, to see what they suggest. Belden was also developing
a "robotics" line of cables, but is wasn't a "popular" segment(in the
corporate sense) of their business last time I checked.

Kabelschlepp and gortite may also be able to point the way, since
their products "carry" the motor cabling; i.e., they might know some
other good motor cable mfrs.

Hope this helps.

P.S. A wire app engineer for belden once told me that a wire in "tick-
tock" usage(which is a hanging "loop", supported at each end) will
last about 30k cycles, comparing this to the same cable in
a "rolling" motion (as is common with any commercial
cable "carriers"), which will then have a life in the millions of
cycles... A helix over a support wire or rod will have a life between
these two, but closer to the low end than the hi-end "rolling" type
life.
