Our Products


 Product Description : Backed by the profound experience of the industry, we offer a wide gamut of Electroplating Rectifier Sets. The rectifier sets are a kind of electronic devices which changes high voltage alternate current (A.C.) into low voltage direct current (D.C.). Moreover, these sets find their applications in any industry, various electro-chemical processes like anodizing and hydrogenation. The process of rectifier sets involve producing a mostly metallic, coating, on a surface by the action of electric current. These electroplating rectifier sets are single or three phase devices on the basis of their rating.

Air-Cooled & Cast Resin Transformers


Winder Power manufactures a range of air-cooled, dry type Class 220 insulated transformers, with or without enclosures. They are particularly suitable for use at high temperature and in tunneling applications.

The units are ideal for installation into switchgear cabinets or ventilated cubicles and present a reduced fire hazard. Winder Power’s air-cooled dry type transformers have gained a reputation for safety and reliability and were chosen by Transmanche Link to supply the power for the construction of the Channel Tunnel under the most arduous of conditions. Air-cooled, dry type class 220 transformers contain no liquid to pollute the ground or water supplies, which means that no measures to guard against spillage are required.

Our design and construction capacity can satisfy many diverse needs and applications, such as autotransformers, earthing transformers, reactors and earthing transformers, transformers for 6-12-18-24-36 pulse rectifiers, HV-HV and  LV-LV transformers, three single phase transformers, triple windings transformers, as well as applications for traction and testing rooms.

Furthermore, cast resin transformers can cope well with overloads found in most typical installations, whilst the quality technology employed in the manufacturing process of windings gives the product high level of reliability.

Applications for Air-Cooled, Dry Type Transformers:

  • Quarrying, tunnelling or mining environments
  • Basements, roofs or any other location in FACTORIES
  • High rise buildings
  • Hospitals
  • Department stores
  • Exhibition halls
  • Subways
