Actually, if the chokes are used to protect the voltage source, the turn
to turn voltage is relatively low. A thinner insulation is quite
adequate. The problem comes in when you start to stack one layer on top
of another. The voltage differential could very well break down standard
insulations. The remedy is to insulate each layer with electrical tape
or some other type of insulator. In that way, you could even use varnish
covered magnet wire, provided the inter-layer insulation is adequate.
