Electrical equipment with explosion-proof enclosures is called explosion-proof electrical equipment. If the explosive gas mixture enters the explosion-proof enclosure and is ignited, the explosion-proof enclosure can withstand the detonation pressure of the explosive gas mixture in the internal structure and prevent the internal explosion from spreading to the combustible mixture around the enclosure. At the same time, oxygen is also ubiquitous in the air.

Explosion proof lamps are lighting fixtures used to prevent explosions. The design principle and structure of the lamp are to prevent electric arcs, sparks, and high temperatures that may occur inside the lamp from igniting combustible gases and dust in the surrounding environment in hazardous areas where combustible gases and dust exist, thus achieving explosion-proof requirements.
