Improved electroplated PTFE for high performance capacitor applications

摘要

The five granulation PTFE material described in this paper exhibits dielectric strength values at least twice as high as those of the general purpose pelletized PTFE. When this high-electric-strength material is combined with the technology of electroplating PTFE, high-voltage capacitors of superior electrical characteristics can be designed. An example of such a design was discussed, involving stacked-disk low-inductance capacitor banks which have characteristics surpassing those of vacuum units of similar electrical ratings.
