Three-Phase Dry-Type Transformers for Rectifier Applications

Application scope

The manufacturer describes production of three-phase dry-type transformers from 150VA to 600KVA using quality materials and developed manufacturing processes.

For AC 50/60 Hz three-phase supplies with input and output voltages not exceeding 1000 V. Input/output voltages, vector group, tap quantity and position (normally ±5%), winding capacity allocation, additional single-phase secondary windings, rectifier-circuit use and enclosure requirements can be designed to customer specifications.

Model designation

SG: S denotes three-phase; G denotes dry-type transformer; suffixes indicate rated capacity in VA and voltage class in V. The adjacent control-transformer designation drawing identifies S: three-phase and BK: control transformer, followed by rated capacity and voltage class.
