Re: [TCML] Where to mount the HV Transformer? Under thecoilorotherwise ?
Yes, this is usually the case and thanks for adding this
footnote. However, I have come across some x-ray
cable where this tape between the silicone insulation
and the braiding did NOT seem to be a semi-conduc-
tor but rather a full insulator. Of course if it IS a semi-
conductor, if you lay it across any high voltage, it will
let you know really quickly by immediately flashing
over and catching fire!

There's also a semiconducting tape layer over the inside silicone
insulation but under the outside grounded braid. Folks, don't forget to
back as well.

High voltage x-ray
cable consist of ususally 3 seperate inner conductors that are
made to carry the low filament voltage to the tube but are also
desinged to ride at many kVs in relation to ground for the high
voltage. There is a thick insulation barrier (~3/8" thick) wrapped
around these three inner conductors and then the grounded braided
sheath is wrapped around the outside of this thick insulation barrier.
Finally, there is a thin vinyl sleave around the outside of the
grounded braided sheath and the total thickness of the cable is
usually around 7/8" thick.
