Really quick question list, does anyone know the average voltage standoff
of single build magnet wire? 100V? 1,000V? 10,000V? I've really no clue
but suspect it would be in the 600-1000V range... Also does double and
triple build insulation make much of a difference? Again toying with
designing a flyback transformer, and just trying to figure things out...
I think the heavier build is used to make a more rugged wire and one
that can take more abuse before it gets *too thin* and breaks down. It
might also have better properties in something like a motor winding that
gets hot (and softens).
An interesting thing about thin insulation layers is that the breakdown
strength is NOT a linear function of the thickness. Multiple thin layers
is much better than one thicker layer with the same total thickness.
Mica has a really high breakdown strength because it's lots of very thin
