Transportable room cell for voltage transformer station

摘要

The room cell is designed to be sunk partially in the ground and has a rectangular base plate integral with vertical sidewalls (16) supporting a roof plate (20), at least one of the sidewalls having an opening for an access door. The upper edge of the sidewall has a shoulder surface (92) extending inwards over part of its width to define a top projection of reduced width supporting the roof plate, with an indent (94) in the sidewall beneath the roof plate. The peripheral edge of the roof plate lies flush with the sidewall surface below the indent.
