FIELD: electrical engineering.
SUBSTANCE: invention is related and in particular to the field of nodes of low-voltage switchgear and control equipment, in particular to the frame structure of the shell. Modular frame structure adapted for the shell of a low-voltage switch gear and control gear assembly, is built with a plurality of corner blocks, corner bars, corner bar extension blocks, cross bars and cross bar extension blocks, assembled together in a certain way, forming a shell frame structure with sealed gaps.
EFFECT: improving the degree of protection against solid objects and water (IP code) of the frame structure of the shell.
