Re: PTFE tape for transformer insulation
Make sure you get the wide PTFE tape: very narrow PTFE tape is now available that is wound within the grooves of the pipe thread rather than across several of them. The plumber used some when fitting a new radiator for us a couple of months ago.
The drums of PTFE-insulated wire that I have, bear prominent warnings about the danger of exposing them to excessively-high temperatures. I have never seen corresponding warnings on pipe thread tape, presumably because the pipe tape would not expected to be subjected to dangerously-high temperatures.
