REDCAP: Size and production costs reduction of very high voltage AC capacitors for switchgears in electricity HV networks

Abstract (German)

To improve the competitiveness of Maxwell Technologies high voltage capacitors on the world market, we intend to develop new surface treatments on polymer films in order to increase their electrical and mechanical performances, and consequently achieve a capacitor size and cost reduction. The work will be oriented in two directions: on one hand increase the environmental resistance regarding ageing and film swelling. On the other hand increase the dielectric strength of the dielectric system. The solution will be investigated with thin polymer or oxide layer deposition on the dielectric film surface.
