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 lighting fixtures generally adopt effective measures to allow internal structures to explode and block spark propagation, which is a commonly used explosion-proof type. This explosion-proof type of lighting fixture casing is generally manufactured using metal composite materials, with strong heat removal, high casing strength, and good durability, which is highly favored by users. In addition, many explosion-proof electrical components, such as sockets, interlocking power switches, etc., also use explosion-proof construction.
