What thickness insulation should I use for 3500 volts ?Wire diameter is dictated by current, not voltage, what is the current draw. Insulation thickness is determined by voltage.
But such wires often have a large series resistance to suppress EMI from the spark, so it may not be suitable for an application that draws any significant current.Spark plug wire connects 20-30KVolts to the plugs.
