Hi
 
I need a low distributed capacitance winding transformer, for a HV
stepup function (3.5kV)
 
I am zeroing in on similar concept as CCFL transformers with
sectionalized bobbin.
 
For example:

ccfl-transformers/fl/
 
Possibly using Triple Insulated Wire to create some distance between the
individual turns.
 
Not many sells CCFLs these days.
 
Guess I will keep it alive....
