box trasformatore mv lv*******The magnetic circuit and the windings are immersed in a liquid dielectric that provides insulation and evacuates the heat losses of the transformer. This liquid expands according to the load and the ambient temperature. PCBs and TCBs are now prohibited and mineral oil is generally used. It is flammable and . See moreThe windings of air transformers are insulated by means of the wrapping of the windings themselves, the mounting of plastic partitions and compliance with adequate insulation distances. A careful commissioning proceduremust thus be followed, so as not to . See moreDry-type transformers, with one or more enclosed windings, are usually called cast resin transformers. These types, due to developments in construction techniques, are more and more widely used because of their reliability, their lower environmental impact compared to . See more

The technology used to make the MV windings of strips, rather than of wire, puts less stress on the insulation between the turns. In windings made with strip conductors, each .
