ELECTRICALLY AND THERMALLY INSULATION SYSTEM OF DRY TRANSFORMERS' WINDINGS WITH HIGHER OUTPUTS

摘要

This solution concerns an insulation system created by distance bars (2) and insulation barrier between the magnetic circuit core (1) and the winding (5), or between the windings (5,6) where the insulation barrier consists of at least four plates (3), from which each of them is loosely or bias-embedded in the vertical side grids (4) of the two neighbouring distance bars (2).IMAGE
