Transformer assembly

A transformer assembly comprising:

• an electrical transformer having a transformer tank with plural side walls, a top wall, and a base wall;
• a housing having a base wall, plural side walls, and a top wall, said transformer tank being positioned inside said housing;
• a device for electrical connection of said transformer to an electrical article outside said housing, said device having a shaped body with a first face for connection to one of said top, base or side walls of the transformer tank, and a second face for connection to one of said base, top, or side walls of the housing, wherein said shaped body comprises at least one deformable portion for adjusting a positioning of said second face relative to said one of said base, top, or side walls of the housing;
• wherein the shaped body of the device comprises:
• at least two hollow components which are mechanically connected to each other with respective cavities in fluid communication, said cavities defining an internal volume which for filling with a dielectric fluid and inside which an electrical conductor is accommodated;
• and
• wherein a first component of said at least two hollow components is adapted to structurally break before a second component of said at least two hollow components.
