As an extension of my previous inquiry into air-core chokes, I'm trying to determine the voltage insulation rating of Enameled Wire, without much luck. Few of the audio air-core choke manufacturers list that data, and none of the enameled wire manufacturers I've checked give it either.
How can I be sure that the insulation on enameled wire will not break down under a given voltage? Am I not looking in the right place for this rating? Am I looking at the wrong kind of enameled wire for high-voltage applications? Are we required to build chokes such that consecutive windings of enameled wire are close enough in voltage that the insulation rating of the wire doesn't matter?
Breakdown voltage depends on the thickness of the covering, which can be of 3 types: Grade 1, Grade 2 and Grade 3. Higher grades have thicker insulation and thus higher breakdown voltages.
The temperature class indicates the temperature of the wire where it has a 20,000 hour service life. At lower temperatures the service life of the wire is longer (about a factor 2 for every 10 °C lower temperature). Common temperature classes are 105° C, 130° C, 155° C, 180° C and 220° C."
The breakdown voltage depends mainly on the thickness of the insulation (see formula below), but also on the bare wire diameter, the application temperature of the coil and the type of enamel.
Xinyu enameled wire has been developed which gives at least an order of magnitude longer life than a conventional enamel. System tests, using this enamel in a form wound coil, have shown that the turn-to-turn capability of this enameled wire is superior to the capability of a reliable service-proven ground wall insulation.

Enameled wire is a common type of insulated electrical wire. It’s typically made from aluminum, and is often used to insulate electrical wiring. Enameled wire is known for its high dielectric strength, which means it has a high voltage current flowing through it. You can check and get to learn most attractive ways for your work. It may be used inside electrical equipment such as electric hot water heaters and electric toothbrushes, or it could be used for catheters and medical wires.

I wrote an essay for a college engineering student on the dielectric strength of enameled wires while working for a website back last year. So even though what you have written is all good you could have given a much better description than this.

We have recently shifted our new office and we are trying level best to incorporate the latest technologies and advancement in our project. The Forces Jackets USA
| have used the dielectric enameled wires for their electricity supply.
