Power & Distribution Transformer
Salient Features
Advanced design to withstand short circuit forces during fault.
Step-up and Step-down transformers manufactured
Low Loss and highly efficient
Pure copper conductor made in own plant to reduce load loss
Thermally upgraded insulation paper(Class A) results in Long life of transformer
Excellent process of shrinkage and vacuum drying of coils resulting in a sturdy construction
Manufactured with prime CRGO using step-lap design for low losses
Thermal treatment of core in own annealing plant to reduce core loss
Less temperature rise of core
Low Magnetizing Current to save no-load electricity bills & capacitors for Transformer.
Inherent overloading capacity due to Low Loss, High power factor and less no-load current.
Lower PD (partial discharge) value
Lower sound level
Transformer tank is filled with oil under vacuum process.
PSR or corrugated radiator
Leak proof, pressure, and vacuum tested as per standard
Self-protected, standard protective devices as per IEC standard
Online monitoring facility (on request)
