Basic Overvie
An explosion-proof cabinet is a specially designed enclosure that is constructed to contain any explosion that may occur inside the cabinet. These cabinets are used to store and protect electrical equipment or devices that are prone to sparking or generating heat, such as batteries, motors, transformers, and switches, in hazardous locations where flammable gases, vapors, or dust particles are present.
The construction of explosion-proof boxis based on the principle of preventing any ignition source from igniting an explosive atmosphere. These cabinets are made of materials that are non-sparking and non-conductive, such as aluminum, stainless steel, or cast iron. The cabinet’s joints and seams are also designed to prevent any sparks or flames from escaping.
Advantages And Characteristics
- Comprehensive protection: Explosion proof cabinets have various safety protection features such as fire prevention, waterproofing, and explosion prevention, which can prevent harmful substances such as odors and pollutants from spreading to the surrounding environment in the working environment.
- Explosion proof internal components: The components installed inside the explosion-proof cabinet also have explosion-proof functions. Even if there is a malfunction or problem with the internal electrical components, it will not affect external sensors or other electrical circuits.
- Strict design requirements: In addition to basic explosion-proof functions, explosion-proof cabinets also need to consider safety performance such as preventing electrical fires, leakage, lightning, insects and ants, dust, moisture, and corrosion.
- Sturdy structure: The outer shell of explosion-proof cabinets is generally made of welded steel plates or cast aluminum alloy, with high-voltage electrostatic spraying. The overall structure is composed of a composite structure of explosion-proof and increased safety shells.
- Clear explosion-proof rating: Explosion proof cabinets are classified into European made explosion-proof rating and American standard explosion-proof rating according to different explosion-proof requirements, ensuring safety in different environments.
- High safety: The explosion-proof cabinet adopts special design and materials, which can effectively prevent accidents such as fires and explosions, and ensure the safety of personnel and equipment.
-
Customized explosion-proof cabinets based on the Turkmenistan refinery. The customized explosion-proof cabinets can be designed according to the special environment and needs of the refinery. The outer shell is made of cast aluminum alloy to help improve the safety and stability of the refinery.
-
Cast aluminum alloy has high strength and hardness, can withstand certain impact and extrusion, and can effectively prevent the damage and leakage of explosion-proof cabinets caused by external forces. Cast aluminum alloy has good thermal conductivity, which can quickly dissipate the heat generated in the cabinet and reduce the risk of explosion.

Application areas
- High risk industrial sites: including explosive gas mixture risk sites (Zone 1, Zone 2), combustible dust environments (Zone 20, Zone 21, Zone 22), and specific temperature groups (T1-T6).
- Outdoor application: The outdoor explosion-proof positive pressure cabinet is designed specifically for outdoor flammable and explosive environments, with features such as rain, dust, and sun protection. It is widely used in outdoor places such as petroleum, chemical, and pharmaceutical industries where flammable and explosive gases, dust, or fibers exist.
- Coal industry: The production environment of the coal industry often contains flammable and explosive substances such as coal dust and gas. The application of positive pressure explosion-proof cabinets in the coal industry is mainly used for the protection and monitoring of underground electrical equipment, which can effectively prevent external flammable and explosive gases from entering the cabinet, thereby ensuring the safe operation of electrical equipment.
- Pharmaceutical industry: The pharmaceutical industry has extremely high requirements for the safety of the production environment, as any minor pollution or malfunction may affect the quality and safety of drugs. The application of positive pressure explosion-proof cabinets in the pharmaceutical industry can provide a safe and clean production environment, ensuring drug quality and production safety.
- Petrochemical industry: In the petrochemical industry, there are a large number of flammable and explosive materials, such as gasoline, diesel, and natural gas. Positive pressure explosion-proof panel use an internal ventilation system to pressure clean air from outside the cabinet into the interior, ensuring that the pressure inside the cabinet remains consistently higher than the external environmental pressure. This effectively isolates and dilutes flammable and explosive gases, reducing the risk of fire and explosion.
