Abstract
A tank for housing electric equipment, which is composed of at least upper and lower parts, with its parting line running in the horizontal direction, and in which the aforesaid upper and lower parts are coupled to each other by means of respective interconnecting flanges formed on the upper and lower parts of the tank, and a plurality of vertical reinforcing stays are secured to the outer surfaces of the upper and lower parts of the tank, respectively. In this tank, the vertical reinforcing stays are secured in a manner that the ends thereof face each other in the vertical direction and the walls of the vertical reinforcing stays at their ends are coupled to each other by means of interconnecting reinforcing members or by welding, so that there may be obtained a continuous or smooth distribution of bending moments over the vertical reinforcing stays, thereby avoiding stress concentration thereon, with the resulting increase in the mechanical strength of the tank.
