  Manufacturing Facilities
 

Infrastructure
Magnewin has two plants. The first one spread over 7000 sq. feet shop floor area where dedicated Research & development activities are carried out. In the second plant which has a total shop floor area of 22600 sq. feet including world class clean room a rea of 31 00 sq. feetfor manufactuing.

Storage
Class "A" raw materials like film, foil and insulation material are stored in a clean and temperature controlled area. Manufacturing Imported bi-axially oriented Double hazy (both side rough) Polypropylene film and Capacitor grade 99.9% pure aluminum foil are used as dielectric and electrode. Wrinkle free elements are wound in a Class 100 environment on a Semi-Automatic winding machines with edge and end folding of the aluminum foil. Each wound dry element is subjected to DC Over voltage test to eliminate faulty elements. Number of elements are stacked together to form a dry pack. Numbers of elements are inter- connected in series / parallel to achieve the desired capacitance and voltage rating of the Capacitor. Internal discharge resistors are provided to discharge the capacitors. The dry pack is wrapped with optimal number of 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 by using semi-automatic welding machine. The Capacitors are then processed in a PLC controlled autoclave for drying and vacuum treatment. Quality of heating, drying and vacuum levels are monitored by using precision online control & monitoring instruments. The Capacitors are then impregnated under vacuum with purified and degassed NPCB Capacitorfluid.

Fabrication
A full fledge in house fabrication shop has been established which incorporates latest hydraulic power press brakes up to 150 tons, power shear, die tools, punches and semi-automatic welding machines etc. These in-house facilities ensure to get the fabricated containers and cubicles, Capacitor mounting frames and elevating structures on time with quality workmanship.

Testing
All Capacitors are subjected to routine tests as per relevant IS / IEC standards. All Capacitors are also subjected to a 20% AC over voltage test to ensure reliability of Capacitors as per company standard. Randomly selected Capacitors are subjected to Type tests as per relevant standards. On regular intervals Capacitors are also tested at independent NABL accredited test labs.

Quality Control
All incoming raw materials are inspected as per relevant standards and specifications. In-process inspections are regularly conducted at each process level. All the records are documented and maintained in accordance with ISO 9001.

Pre-dispatch Inspection
Each Capacitor unit / bank / panel undergoes pre dispatch inspection by the QC department. Capacitors are packed carefully so that the equipment reaches the client securely and safely without any transit damages.

Research & Development
Research & Development is a continuous ongoing activity being carried out to enhance the reliability & life of Capacitors and adopting cost reduction techniques by improving and adopting new manufacturing techniques, automation, installing precision on line instruments to monitor the behavior of Capacitors during process etc. Formulating new rigorous in-house test standards to assess life expectancy and behavior of capacitors under extreme operating & environmental conditions. Developing new dielectrics, Capacitors as per customer's specifications are primary objects ofthe R & D Department. Our engineers have also been working on developing high energy density
Capacitors in compact size.
Today "Magnewin"is proud to be the only company in India to manufacture such a wide range of Capacitors, which has been possible on account of its innovative thinking & strong technical base, R & D and the passion of the management to keep research and development as an ongoing process.

Life Expectancy
Thanks to the state of art plant & machinery, world class raw materials, manufacturing process with strict quality control using precision on line monitoring instruments, material handling systems and over voltage tests under extreme environmental conditions, Magnewin Capacitors are assured for minimum 20 years of trouble free working life, under normal working
conditions.

Training
Learning is a lifetime process. So training is considered as the most important tool to develop the skills of our both commercial as well as technical staff. Regular in house training sessions are conducted by seniors from the company as well as by invited experts in Electrical Power systems and management.
