A flameproof enclosure’s effectiveness stems from its ability to contain flames within, na dia misy fipoahana ao anatin'ny casing fitaovana elektrika aza. Io fitahirizana io dia azo antoka amin'ny alàlan'ny fisorohana ny lelafo tsy hivoaka amin'ny alàlan'ny sehatra iraisana.
Ny fanarahana ny fenitra manokana momba ny elanelana, NY FAHARETANY, and surface roughness of these joints is crucial. These gaps not only extinguish the flames but also cool them effectively. They reduce the temperature of the flames passing through to a level insufficient for igniting any baomba mixtures that may be present outside the enclosure.
