A stationary electrical device that utilizes electromagnetic induction to transform voltage or current between two or more windings at the same frequency.
SG and SBK three-phase dry-type transformers feature a core and windings that are not immersed in insulating liquid medium. Instead, they are directly exposed to air, relying on natural convection for heat dissipation.
The SG-type three-phase dry-type rectifier transformer is a crucial component in rectifier equipment, forming rectifier circuit systems when combined with various rectifier devices. To convert alternating current (AC) into direct current (DC), the rectifier transformer first transforms the voltage from the AC grid into a voltage of specific magnitude and phase number before passing through the rectifier device.
