Re: Pigs and X-Ray Cabling
I have also used some of the Xray cabling for my tesla coil. I run a 10
KVA pig with a welder for current limiting. The cabling I use sounds
pretty similar with the multiple conductors and shielding. What I did was
use a 15 foot chunk for each lead. i stripped back about 8 inches of hte
shielding on each end and covered the exposed edges with electrical tape.
The conductors on the inside were all tied together. I haven't had any
problems witht the cables at all. I just let them lay on the ground
(usually dirt) and not worry about arcing between them. The cable I have
came from an CT scanner which has an Xray tube in it. If you expect
longer streamers than I did, go ahead and make the leads longer. Happy
Coiling! Mike Bauer
