Abstract
A tank for electrical equipment such as power transformers and shunt reactors has integral stiffeners for reinforcing the tank during overpressure conditions, such as during an arc fault. The stiffeners are formed of a material that is more ductile than the material to which the stiffeners are attached, such as the tank walls and cover. The tank with integral stiffeners allows for expansion of the internal volume of the tank during overpressure conditions, thus, increasing the flexibility of the tank and mitigating the risk of tank rupture.
