Equipment overview

Built around the confirmed duty

The 2026 manual documents four 220 kV power-transformer arrangements: double-winding off-circuit regulating, double-winding on-load regulating, three-winding off-circuit regulating and three-winding on-load regulating. Capacity and voltage combinations vary by the selected handbook table.

Working principle

Electromagnetic induction transfers power between the selected two- or three-winding system. The tap-changing arrangement regulates the output ratio either under load or while de-energized.

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

  • Four documented winding and voltage-regulation arrangements
  • Capacity and ratio selected from the confirmed system duty
  • Oil-immersed transmission-class construction
