<p>The immersion-type electrical apparatus described offers increased safety in the event of an external fire. The apparatus comprises means associated with the tank in order to restrict the transmission of external heat energy to the liquid dielectric, said means being in the form of a reflective coating on the tank, such as a reflecting metal paint or zinc deposit, and if applicable, an added reflective wall (17), surrounding the transformer tank. Application: all electrical equipment of the immersion-type in which the tank contains a dielectric liquid, and in particular high-voltage/low-voltage public network transformers.</p> |
