Equipment overview

Built around the confirmed duty

The 2026 product manual documents 330 kV oil-immersed three-phase double-winding and three-winding off-circuit voltage-regulating power transformers. The handbook tables cover multiple rated capacities and voltage combinations; final guaranteed values remain tied to the selected row and technical quotation.

Working principle

The oil-immersed magnetic core and windings transfer bulk electrical power between transmission voltage levels. The selected winding and off-circuit tapping arrangement is engineered to the grid duty.

Power and transmission equipment selection is based on power or torque, speed, load profile, service factor, electrical supply, mounting, environment, efficiency and integration requirements.

Core features

  • Two- and three-winding configurations documented
  • Multi-dimensional electrical, magnetic, thermal and mechanical design review described in the manual
  • Source manual states routine and short-circuit testing evidence for the cited SZ22-63000/110-NX1 design
