P.S.
we are currently making some CAT wire with combined Optics and
rein forced binders made of Kevlar along with some high current control
wires as a composite cable to be used in future homes and businesses.
should be interesting. we have never combined those types of components
in one cable before.
so far, testing on the samples appear to be passing very well on the
CAT and control wires. i think this maybe due to the fact that we have
put lightly braided shield around those.
Btw.
putting Cat wire in a race way that houses high current wires for
drives DC/AC has prevent to not work well for our electricians. it
took them aprox 3 mounts of playing around with a machine that was
having a very slow response rate reading data from controllers via a
Cat 5 . it turned out that, many errors were being generated in the
interface and thus the network connection was doing alot of resends
or waiting for updated readings thus causing the machines performance
to be unpredictable.
running the CAT 5 in its own race way solved that problem.

To let you in on something, our
facility was one of the first to
start massive manufacturing of CAT 4,5
and the like along with the foam pairs
bundled with twisted pairs of control
wires etc...
high levels of DC currents pulsing
over long runs bundled in the same
race way with no form of EMF shielded
does un-balance the Twisted pairs there
by influencing the signal.

How about sharing some of that vast experience and tell us how induced voltage
unbalances a balanced cable pair by "influencing the signal." What work did
you do in that lab?
Don
bandpass, cross over, burn test for smoke, copper purity, rip cord break
