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 elect utility / 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 2020.

Training at Magnewin
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.
Magnewin has two plants the first one spread over 7000 sqft shop floor where exclusively Low Voltage capacitors are manufactured and the second one which has shop floor area of 15000 sqft where all the other ranges (which need to comply stringent standards) are manufactured. Separate store, (clean air-conditioned) for Class “A” raw materials like Film, foil, insulation material and impregnant and separate store Class “B” for rest of the materials is maintained. Modern material handling equipment's are being used. Plant, machineries and testing instruments required for manufacturing are the latest one to complete all routine and type tests (except Impulse test) as per relevant IEC and BIS standards.
Few custom built test equipment's / power source have been developed to simulate test conditions for overload testing of MFWC capacitors of a wide range which is one of its kind in India.
A full fledge in house fabrication shop has been established which incorporates latest hydraulic power press brakes, power shear, die tools, punches and semi-automatic welding machines. These in house facilities ensure to get the fabricated containers and cubicles on time with quality workmanship.
All the major raw materials like double hazy film , Al foil and NPCB oil are all imported from the reputed manufacturers from Japan, France, Korea and USA .
Capacitor manufacturing starts in specially fabricated clean rooms in line with international clean room standards. 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 zone 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. Soldering and electrical connections are carried out to achive the desired mfd and voltage rating of the dry pack. After wards the pack is wrapped with several layers of high grade insulation paper and is then 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 operations & moment of dry capacitors from winding stage till pack insertion into the containers is done on specially designed motorized conveyors.
The welded dry capacitors are placed in an PLC controlled Heating cum Vacuum drying autoclaves 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 sealed and subjected to all routine tests as per IEC 60871-1 and then subjected to 20% A C overvoltage test for a pre-determined period as per company standards. All the passed capacitors are grit blasted, followed by air drying epoxy paint.
Research & Development
Research & Development is a continuous on going 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 asses' life expectancy and behavior of capacitors under extreme operating & environmental conditions. Developing capacitors with new dielectrics is also one of key area of R & D.
Our engineers have also been working on developing dielectric materials and impregnants for use in special application capacitors for making 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 strong technical base, R & D and the passion of the management to keep research and development as an ongoing process.
