<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Very pure deionized (DI) water has low conductivity, and is used in some HV apparatus, mostly because of the spectacularly high dielectric constant (80). It’s also used in some clever cooling systems where the anode of the tube is at HV, but the pump and radiator is at ground potential.<BR>
The problem is that you have to keep the water pure, because it’s always dissolving whatever it’s contacting.<BR>
The other problem is that liquid containing systems almost always leak.<BR>
