Separate store (clean air conditioned) is used for Class "A" raw materials like film, foil and insulating materials. Another store for rest of the materials is maintained. All the materials are carefully handled using latest material handling equipment. The plant consists of necessary machinery for winding the elements, their testing and assembly for the capacitors.

The plant also consists of the latest facilities for carrying out the routine and type tests as per national and international standards. The special application capacitors are also tested according to the prescribed specifications by the customer.

Imported bi-axially oriented double hazy (both side rough) polypropylene film and capacitor grade 99.9% pure aluminum foil are used as a dielectric and electrode. Wrinkle free elements are wound in a class 100 environment on semi-Automatic winding machines with edge and end folding of aluminum foil. Each wound dry element is subjected to DC over voltage test to eliminate faulty elements. Numbers of elements are stacked together to form a dry pack.

They are interconnected in series/parallel combinations to achieve the desired capacitance, voltage and kVAr ratings for the capacitor. Internal discharge resisters are provided across each capacitor to reduce the voltage below 75 volts within prescribed time as prescribed in the standards. The dry pack is wrapped with optimal number layers of high quality insulating paper before inserting into a pre-treated sheet metal container. Leak proof porcelain bushings of appropriate BIL are TIG welded on the embossed top lid, which is TIG welded to the container-Automatic welding machine.

The capacitors are then processed in PLC controlled autoclave for drying and vacuum treatment.The heating, drying and vacuum levels are monitored by using precision online instruments for preserving the quality of capacitors. They are then impregnated under vacuum with purified and degassed NPCB capacitor fluid.
