1、 Explosive gas environment

• regional divisionSuitable for hazardous gas locations in Zone 1 and Zone 2. According to the frequency and duration of the occurrence of explosive gas mixtures, explosive gas environments are divided into Zone 0, Zone 1, and Zone 2. Among them, Zone 1 represents environments where explosive gas mixtures may occur during normal operation, while Zone 2 represents environments where explosive gas mixtures are unlikely to occur during normal operation, or where they only exist for a short period of time.
• Category and GroupSuitable for Class IIA, IIB, IIC explosive gas environments. These categories are classified based on the maximum test safety gap (MESG) or minimum ignition current ratio (MICR) of explosive gas mixtures. Meanwhile, it is also applicable to environments with temperature groups T1-T6, which are divided based on the ignition temperature of explosive gas mixtures.

2、 Flammable dust environment

• regional divisionSuitable for areas with combustible dust in zones 20, 21, and 22. These areas are divided based on the frequency and concentration of combustible dust.

3、 Outdoor environment

• Protection levelOutdoor explosion-proof lighting power distribution boxes usually have high protection levels, such as IP54, IP55, or IP65, to ensure normal operation in harsh outdoor environments and prevent water, dust, etc. from entering the interior of the box.
• environmental adaptabilityCapable of adapting to various outdoor climate conditions such as high temperature, low temperature, humidity, salt spray, etc., while maintaining stable explosion-proof and electrical performance.

4、 Application Fields

• industrial sectorWidely used in industrial fields with explosive hazardous environments such as petroleum, chemical, mining, textile, printing and dyeing, medicine, military industry, and military facilities.
• other fieldsIt is also suitable for outdoor lighting, power line distribution and other places that require explosion-proof performance.

In summary, outdoor explosion-proof lighting power distribution boxes are suitable for distribution needs in various explosive gas and dust environments, as well as harsh outdoor weather conditions. When selecting and using, reasonable configuration and installation should be carried out according to the specific usage environment and requirements.
