The difference between explosion-proof lights and ordinary lights is the installation method. The most important thing for explosion-proof electrical appliances is that they cannot be grounded, as grounding will easily generate sparks, and most of the power cords are explosion-proof and flame-retardant. Generates electrical sparks that ignite explosive mixtures. The difference in wiring also directly leads to the difference in the scope of use of the two.

Shade material

The difference between explosion-proof lamps and ordinary lamps is that the material of the lampshade is different, but the lampshade is different, and the lamp tube inside is the same. The explosion-proof lampshade is made of high-strength glass and metal mesh, which also determines the difference in the use of the two.

The difference between explosion-proof lamps and ordinary lamps_Different use environments

The difference between explosion-proof lamps and ordinary lamps is the use of different environments. Both explosion-proof lamps and ordinary lamps are lamps, which are used as lighting in production, storage and rescue. This is the common point of explosion-proof lamps and ordinary lamps. In addition to ensuring the safety of general lighting fixtures, the surface temperature of explosion-proof lamps must be lower than the ignition temperature in an explosive environment during normal operation or when the lamps fail, because different explosive environments, its dangerous gases or Dusts have different ignition points.

different national standards

Explosion-proof lamps and lanterns should be marked with "Ex" + explosion-proof type and explosion-proof grade + temperature group in the obvious part of the shell and on the nameplate in accordance with the requirements of national standards (see the next chapter for explosion-proof type). The explosion-proof mark contains the product. Use the basic information of explosion-proof standards, such as "Ex BT4" should comply with GB3836.2 standard; "Ex eT4" should comply with GB3836.3; "ExdeBT4" should comply with GB3836.2 GB3836.3 standard. At the same time, the nameplate must have the code of the testing unit and the approved serial number, also known as the explosion-proof certificate number.
