Transformer
A static device transferring energy between circuits through electromagnetic induction, changing voltage and current levels.
A transformer transfers energy between circuits via electromagnetic induction. AC current in primary winding creates flux in core, inducing voltage in secondary proportional to turns ratio.
Most efficient energy conversion device (95-99.5%). Enables AC power systems: step-up for transmission, step-down for utilization. Types: power, distribution, instrument, dry-type.
QDTB is a leading manufacturer from distribution to EHV ratings, meeting IEC, IEEE, and GB standards.
