Electrical stack and layer construction

Abstract

Abstract Electrical stack or layer condensers produced by dividing a master condenser into individual condensers have dielectric properties at the edges produced by their separation from the master condenser, which properties are substantially the same as those portions of the condensers intermediate the edges. The individual condensers are produced by breaking up the metallic coatings on the individual dielectric layers adjacent the edges formed during separation from the master condenser. In one embodiment, the individual dielectric layers are of a cast plastic material containing about 0.25 percent solvent residues. The heat buildup during cutting to separate the individual condensers and the solvent residues permit breakup of the metallic coating adjacent the edge being formed to provide a dielectric condition at the new edge which prevents arcing of oppositely poled layers along the new formed edges. Another embodiment employs metallic coated layers of plastic, alternately cast and extruded foils, to improve the regenerative properties of the condenser and to prevent arcing or breakdown at the edges of the individual condensers.
