         1. Lighting fixtures explosion proof for explosion-proof categories, levels and temperature groups are subject to national standards.

         2. According to the explosion-proof type, there are 5 main types of lighting fixtures explosion prooftype, increased safety type, positive pressure type, non-sparking type and dust explosion-proof type. It can also be combined with other explosion-proof type and various types of explosion-proof type or composite type and special type.

            3. According to thelighting fixtures explosion proof type of protection against electric shock, it can be divided into categories I, II and III. 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.

          AI class - On the basis of basic insulation, connect the electrically conductive parts that are accessible during normal operation without electricity to the protective earthing conductors in the fixed line.

        Class BII - Use double or reinforced insulation as a safety measure without grounding protection.

        Class CIII - Use a safe voltage with an effective value of no more than 50v, and no higher than this voltage value will be generated.

        Class D0 - rely solely on basic insulation as a safety measure. Most of the explosion proof lighting suppliers in uae are protected against electric shock, and only a few are              Class II and Class III lamps. For example: all-plastic explosion-proof lamps, explosion-proof flashlights.

                  4. Classified 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 flashover, short circuit or damage to electrical insulation. The role of 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 lighting suppliers in uae are sealed luminaires with a dust-proof capacity of at least 4 or higher. The second number indicates the protection against water and is classified into 0-8.

             

             5. Classification of support surface materials according to luminaire design: Indoor explosion proof lighting suppliers in uae 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 lighting philippinescan 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 flammable materials, with marking symbols.
