Abstract
Insulating paper with a dielectric constant of 6 is metal lized on both faces in mutually insulated zones, each acting as one electrode of the capacitor, and rolled up with plastic foil in such a way that the two are interleaved alternately and that the dielectric ratio of the paper to the foil is 3 - 4 : 1. The impregnant used is such that the plastic foil swells and has a dielectric constant of 2.2 which is approx. equal to that of the plastic. Esp. the impregnant is a low polymer polyiso - butylene.
