Explosion-proof street lights, the highest explosion-proof grade of explosion-proof type, can be used safely in various flammable and explosive places. Used for heavy-duty enterprises in dangerous production, engineering street lights for construction, and explosion-proof street lights are specially designed for petrochemical, chemical, petroleum and other sites.

Explosion-proof street lights used for heavy-duty enterprises in dangerous production

Explosion-proof street lights are divided into: explosion-proof type d IIB level, d IIC level; increased safety type e II level.    
Applicable temperature ranges T2, T3, T4, T6, choose different explosion-proof grades and corresponding temperature group explosion-proof street lights according to the explosion-proof area.    
Commonly used light sources for explosion-proof street lamps: incandescent lamps, self-ballasted mercury lamps, energy-saving lamps, LED light sources, high-pressure sodium lamps and metal halide lamps, etc., when using high-pressure sodium lamps and metal halide lamps, explosion-proof electrical boxes (with built-in ballasts) are required , trigger, capacitor), the gas discharge light source needs a ballast to light up and play the role of ballast;    
1. For explosion-proof street lights equipped with explosion-proof electrical boxes, during the construction process, it is necessary to pre-dig the foundation pit and bury the explosion-proof electrical box in the foundation pit;    
2.Because the explosion-proof electrical box itself has a rainproof and anti-corrosion function, some construction workers directly install the explosion-proof electrical box on the ground near the street light pole for easy maintenance and access.


1. Most explosion-proof street lamps are installed outdoors, so it is very important to choose explosion-proof street lamps. First of all, both the lamp holder of the explosion-proof street lamp and the explosion-proof electrical box must reach the explosion-proof level.
2. The protection level must be above (IP) 54, the anti-corrosion level (WF) should be above level 1, and the insulation should be above level 1.
3. Finally, connect a grounding wire to the grounding terminal outside the ballast.
4. The scope of use when metal halide lamps and sodium lamps are used with explosion-proof street lamps. Generally, the light emitted by metal halide lamps is white and is mostly used in areas with little fog, while the light emitted by high-pressure sodium lamps is yellow light, which is mostly used in foggy urban areas. The penetration of light to fog is relatively strong.
