Electricity has now been considered as the life line in the rapid growth of any developing country and India is no exception to it considering its march towards becoming a super power in years to come. In current scenario the bridge between generation and demand is widening every day, even though all attempts are made to minimize it. Under the given situation it becomes imperative to use the available power at its highest efficiency and use of capacitors takes the first & foremost step in energy conservation.
"Magnewin" is committed to develop highly reliable capacitors, be it required for electrical utilities / for industry / for defense or for R & D institutions. "Magnewin" is committed & proud to develop environmental friendly world class technologies / materials and products that save valuable Foreign exchange and make our country self- reliantin its path of progress to become super power. We at " Magnewin " are proud to be shareholders in the National Energy Conservation programme of India. Magnewin will be known globally as one of the most respected capacitor manufacturing company by 2021.

To see beyond the horizon, challenging ourselves for continued betterment, to move forward with competitive spirit abd strive to develop the most preferred products in-house with our own standards
To be the most preferred electrical manufacturer nationally and globally under the brand name of Magnewin
Company adopts internationally followed latest technology, sells products at competitive prices, attempts to deliver as per the agreed upon schedules and promptly cariies out after sales service & attends to the maintenance problems, if any; keeps in touch with customers & obtains feedback continously for corrective actions so as to improve the quality & reliability.
Training is considered as the most important tool to develop the skills of our both commercial as well as technical staff. Regular Training is imparted by seniors from the company as well as invited guests who are experts in Power capacitor manufacturing.
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.
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.
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.
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.
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 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.
