ABSTRACT:
A medium high voltage capacitor roll section comprises a sheet of double metallized plastic film and a sheet of paper adjacent thereto, with the paper and film forming parallel dielectrics. A dielectric liquid impregnant is used and the roll is wound sufficiently tightly so that after impregnation with a dielectric liquid impregnant and consequent swelling there is an essentially zero negative space factor within the roll.
