FOERFARANDE FOER FRAMSTAELLNING AV EN ELEKTRISK KONDENSATOR MED LAONG HAOLLBARHETSTID.

摘要

A method is described by which the residual moisture can be removed from wound capacitors containing dielectric layers of thermoplastic plastic material, the residual moisture being broken down by electrochemical decomposition and the break-down products removed by vacuum. Capacitors which are subjected to this treatment have a longer service life.
