Flameproof switchgear is a type of electrical equipment designed to prevent the propagation of an explosion or fire from within the equipment to the external environment. It is typically used in hazardous areas such as petrochemical plants, oil refineries, and chemical processing facilities where the presence of flammable gases, vapors, or dusts pose a potential explosion hazard. Flameproof switchgear is constructed with flameproof enclosures that are designed to contain any explosion within the enclosure. The enclosures are typically made of heavy-duty materials and are designed to withstand high pressures and temperatures. In addition to the flameproof enclosure, flameproof switchgear also features special seals and gaskets to prevent the entry of flammable gases or dust into the enclosure.
