A lot of the Tesla coil, etc people insulate their wires with silicone rubber

I have seen diode strings built up out of lots of cheap diodes (like 1000V
1N4007s). The diodes are strung together and then crammed into the silicone
tubing. The ends are sealed and the tubing is then filled with mineral oil
(some people use vegetable oil).

power supply diode and resistor strings covered in heat shrink but don't touch
as it is not good at HV.
Such series strings of non avalanche rated diodes like 1N4007's without
suitably proportioned parallel RC networks almost inevitably fail.
