Abstract

The invention relates to a non-explosive medium/low tension transformer under permanent overload conditions. The transformer comprises a metal case 1 containing the insulated primary and secondary transformation windings. The transformation windings 2 are immersed in an insulating fluid 20. The insulation of the primary and secondary windings 2 is achieved per pair of synthetic insulating materials (10, 20). Application to transformers such as transformers suspended on poles or fixed transformers. <IMAGE>
