[GreenKeys] Teletype signalling (Loop) cable...

[Pete Lancashire]

I have a box that I found at a garage sale, I'll guess 1/2 full. I got it
more
for the cool logo on the box :-)

The last current loop, audio, you name it wiring I did at home was using
Belden ???, A 500 foot spool made out of wood that was a great source
of splinter was from a company going out of biz sale. Don't know the
p/n but it is 3 pairs 20 gauge, each pair is foil wrapped and then the the
whole
thing is foil wrapped. I have not idea what it was designed for. But it is
not
light and not very flexible.

As to using wire from China, a previous comment is most of the wire is
junk is something I totally agree with. If there "UL" written anywhere it
either means nothing or what was sent to "UL" is not what is in your hands.
