Manufacturing :

Capacitor manufacturing starts with clean rooms.The complete manufacturing and operations starting from winding till insertion of dry packs into the container and top lid welding are carried out in a class 10000 and element winding is carried in class 100 zone on four semi-automatic precision winding machines. Aluminum foil, which acts as electrode has its end and edges folded during winding of the element. Element winding is done as per the data from the design software, wound elements are tested and healthy elements are stacked to achieve the desired capacitance and voltage to form a dry pack.

This dry pack is inserted into pre-treated, degreased sheet metal containers and top lid welded with TIG welding. Porcelain bushings of adequate BIL are TIG welded on the top lid. The welded dry capacitors are placed in an PLC controlled Heating cum vacuum drying autoclave and heated at 85C under a vacuum of 0.001 torr until all the capacitors are declared perfectly dried by on line precision instruments. After drying the capacitors, they are impregnated with purified, degassed and tested impregnant Jarylec 101 D under specific vacuum and temperature.

The impregnated capacitors are subjected to routine tests as per IEC 60871-1 and then subjected to 20% A C overvoltage test for a pre-determined period. All the passed capacitors are sand blasted, followed by air drying epoxy paint.
Pre dispatch inspection for each capacitor is carried out before dispatch.
