Hwall ≥ Htransformers? And maybe Ww ≥ Wt? (Just a guess from "first principles.") See local Codes.

The basic principle is to avoid spreading of fire from one transformer to other.

The height of the wall is to be higher than the height of the transformers.

Width of the Fire wall is to be minimum 230 mm if it is brick wall or 150 mm if it is concrete wall.

The is the norm followed in India
