Magnewin Energy Private Limited is an ISO 9001:2015 Certified and a Custom-built Capacitor manufacturing Company professionally organized. We are Manufacturer, Supplier, Exporter of our product range and majorly we serve customers from Australia, Bulgaria, Bangladesh, Bolivia, China, Columbia, Egypt, France, Iran, Italy, Malaysia, New Zealand, Poland, Romania, South Africa, Turkey, USA. It is managed with long standing experience, profoundly interested in Enhancing Power and possesses an exceptional track record since its inception.

It was started with a humble beginning in the year 1994 at Sangli (Maharashtra) and reached the status of a leading manufacturer of capacitors for variety of applications in power system utilities, industries and research activities. Over the years 'Magnewin' has developed its own capacitor manufacturing processes using high quality imported raw materials. Tests are carried out rigorously abiding by the National & International Standards. The products have been regularly exported to more than 20 countries
It retains its position as one of the leading manufacturers of shunt capacitors for power frequency applications in - LV / MV / HV systems both fixed and automatic switched type and shunt passive tuned / detuned filters. 'Magnewin' also has been catering to the needs of specially designed water cooled capacitors for industries such as induction heating, melting and hardening applications; custom - built for energy storage, pulse discharge, medical equipment, impulse generators & voltage dividers and so on.

'Magnewin' is a unique enterprise that can address the critical needs of industries and utilities having sophisticated controllers and facing power quality related problems. We have been developing capacitors to meet the stringent requirements under adverse conditions of operation and offering solutions for energy conservation.

Salient features of Magnewin Capacitors :
  • Raw material used are of world class quality, sourced from best manufacturers in world.
  • Elements are wound in totally dust free ( 100 PPM class ) winding room on a Automatic Winding Machine.
  • Extended Foil design is used to minimize inductance and contact resistance, resulting in very low losses.
  • Elements are externally connected in series / parallel combination by a unique process of soldering.
  • Very Low values of equivalent series inductance ( ESL ) and resistance ( ESR ) Capactiors most suitable for :
    a) Frequent Switching Operations
    b) Large inrush current and out flow current handling capacities.
  • World class sophisticated ( impregnation ) vacuum chambers are used for Impregnation of Capacitors with Non-Toxic, Non-PCB Oil under a very high degree of Vacuum.
  • Every Capacitor unit manufactured undergoes testing as per relevant applicable standard.
  • Randomly selected Capacitors are subjected to Type Test. Magnewin does have in house testing equipments like Impulse test Generator for Impulse Test, Schering Bridge for measurement of tan delta ( losses ), Inductance measuring equipments. We also get the capacitors tested periodically from the Independent NABL accredited test labs in order to ensure Quality.

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.


"MAGNEWIN" will be one of the "MOST RESPECTED" Capacitor manufacturer in the world by 2020.
