What Is Explosion Proof Lighting Classification?

       Explosion proof lighting are a type of luminaire with explosion-proof performance. Explosion roof lighting classification mainly include explosion-proof type explosion-proof lamps, safety type explosion-proof lamps, mobile type explosion-proof lamps and so on.It refers to a dangerous place for the presence of flammable gases and dust. It can prevent arcs, sparks and high-temperature flammable gases and dusts in the surrounding environment, thus achieving explosion-proof requirements.Explosion-proof platform lights are suitable for lighting in flammable and explosive places such as petrochemical plants, oil platforms, gas stations, oil pump rooms, and transfer stations. Explosive gas environment in Zone 1 and Zone 2. Combustible dust environment in Zone 21 and Zone 22.

               Explosion proof lighting classification are divided into five main types: explosion-proof type, increased safety type, positive pressure type, non-sparking type and dust explosion-proof type according to the explosion-proof type. It can also be combined with other explosion-proof type and various types of explosion-proof type,special type.The types of explosion-proof lamps can be classified into I, II and III according to the type of protection against electric shock. The anti-shock protection is to prevent the parts of the explosion-proof lamp housing from being easily touched, so that the human body is exposed to electric shock or conductors of different potentials to generate an electric spark to ignite the explosive mixture. Explosion proof lighting classification according to the degree of protection of the enclosure,in order to protect dust, solid foreign matter and water from entering the lamp cavity, touching or accumulating on live parts, there is a risk of flash over, short circuit or damage to electrical insulation. Protect the role of electrical insulation. Use the characteristic letter "IP" followed by two numbers to characterize the degree of protection of the enclosure. The first number indicates the ability to protect against humans, solid foreign objects or dust. Divided into 0-6. Explosion-proof luminaires are sealed luminaires with a dust-proof capacity of at least 4 or more. The second number indicates the protection against water and is classified into 0-8.

                  Explosion proof lighting classification according to the support surface materials design: Indoor explosion-proof luminaires may be installed on many surfaces of common flammable materials, such as wooden walls and ceilings, which do not allow the temperature of the installation surface of explosion-proof luminaires to exceed safe values. According to whether the explosion-proof lamps can be directly installed on the surface of ordinary combustible materials, they can be classified into two categories.One type is a luminaire that is only suitable for installation on a non-combustible surface.The other type is a luminaire suitable for direct mounting on the surface of ordinary combustible materials, with marking symbols.
