Abstract
A capacitor for a AC applications is manufactured from zinc alloy metallized polypropylene sheet material. The sheet material is wound into one or sections having a roll-shape, which sections are placed within a metal container and provided with electrical terminals for connecting to the exterior of the container. The metal container is then filled with a potting compound comprising 80%-90% blown asphalt and 10%-20% wax additive. When the potting compound sets, the capacitor sections are sealed therein so as to be protected from air, moisture and thermal and electrical shock. The container is then covered with a top which includes a pressure interrupter, and it is sealed. This capacitor exhibits improved resistance to deterioration due to environmental factors over long periods of time, and it permits operation with higher voltages than was previously possible.
