Plant has a total shop floor area of 22600 sq. feet including world class dust free room of area 3100 sq. feet for manufacturing all the types of capacitors. 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.

Fabrication
The Fabrication Division has full - fledged in house fabrication shop incorporates hydraulic power press break 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 and are also subjected to over voltage to ensure voltage withstand capability as per the company policy. Randomly picked up capacitors are subjected to Type test as per the relevant standards . Further, at regular intervals capacitors are tested at independent NABL accredited laboratories to ensure the quality and reliability.

Uality Control
Quality Control is an essential feature and all the incoming materials are inspected as per the relevant standard 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-despatch Inspection
Each capacitor unit / bank /panel undergoes pre dispatch inspection by the quality control department. Equipment's are packed carefully so that they are received by the customers securely and safely without any transit damage.

Life Expectancy
Life Expectancy is another important aspect for which the company has been paying much attention. But for the state of art plant and machinery, use of world class raw materials, updated manufacturing processes with strict quality control through precision online monitoring instruments, proper material handling systems and rigorous testing under extreme conditions - Magnewin capacitors can be assured for minimum 20 years of trouble free service life under normal working conditions.


R&D is continuous ongoing activity being carried out to improve the quality, enhance reliability and increase the service life of capacitors. Quality improvement techniques are in progress by further improving the manufacturing processes, through accurate automation and installing additional precision online instruments for monitoring the quality of capacitors at every stage. The tasks are to formulate new rigorous in-house test standard to assess life expectancy and behavior of capacitor under adverse operating and environmental conditions. Developing new dielectrics with high energy density for compact size and capacitors for special applications are the primary objectives of R&D department.
At present 'Magnewin' is proud to be the only company in India to manufacturer such a wide range of capacitors, which could be possible on account of its innovative thinking, strong expertise knowledge coupled with practical skills, passion for research and development through innovative thinking. R&D is an essential prerequisite in the highly competitive world for successful running of a manufacturing industry like ours due to the fast changing technologies & to keep abreast of the developments.
