Salient Features

Electroways rectifier equipment are wound with electrolytic Prime grade copper strip to minimize power losses, Our equipments are designed liberally as per capacity and are Ideally suitable for marginal over loading conditions. We use SCR Technology for output control, protections and regulation by built-in electronic stabilizer .

DIODES: Silicon diodes are tested in-house, similar PIV batch and same forward drop diodes are used in the equipment for equal load sharing and reducing the power losses of diodes.
LAMINATION CORE: We use imported lamination core which have minimum power losses and results in better efficiency of equipment and saving in energy bill.
PAINTS: We are painting the equipment with Epoxy paint which is resistant to acidic environment of plating process and enhance the life of the equipment by preventing it from corrosion.
METER: We use reputed make European DC meters only which are very accurate and durable.
SERVICING: Electroways have maintained enviable reputation in market in after sales service.
