Auxiliary Transformer for Power Stations and other facilities

Description

Description

The auxiliary transformer is manufactured for 6kV to 35kV of primary voltage. Increased short circuit strength is an additional feature that is supposed to be considered while designing.

Design Features

Design Features

Magnet Core

  • Rolled Grain Oriented Electrical Steel with low specific loss;
  • Steel stacking with tilt joint of the steel strips by Step-lap Process

Windings

  • Manufacturing process ensured making windings with the stable dimensions within the whole life cycle
  • Transposed wire allows enhancing electrodynamic properties and mechanical strength of windings under short circuit, and reduce incidental loss in windings.

Active Part

  • Active Part design ensures 1.5 times reduced incidental loss within their structure.
  • Due to fit-up system and marking of each part, the possibility of any design error is eliminated, and therefore, assembling of transformers is facilitated.
