Re: [TCML] Where to mount the HV Transformer? Under thecoilorotherwise ?

Phil,

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!
