Heavy Duty Capacitors are metallized polypropylene (MPP) capacitors. The capacitors come with stacked windings. The box capacitors are impregnated with a non-PCB biodegradable resin The cylindrical Capacitors are subjected to an extended period of drying after which the casing is filled with an inert gas to prevent corrosion of the winding elements and inner electrical contacts. Compact design ensures space saving.
