Why can’t Class I explosion-proof electrical equipment be used in factories?

What kind of factories cannot use it? Explosion-proof electrical equipment all has specified requirements regarding its operating environment.

Explosion-proof electrical equipment is mainly used in petrochemical plants; it should also be usable in ordinary factories, unless in special working environments

Select appropriate explosion-proof electrical equipment based on the classification of hazardous areas; this generally relates to flammable gases. What the original poster said isn’t clear; it’s not known which factory it refers to. In places where there are no flammable gases, explosion protection need not be considered, and only the protection rating needs to be taken into account.

Who says explosion-proof electrical equipment can’t be used in factories? If cost isn’t a concern, go ahead and use it. Explosion-proof electrical equipment should be selected based on the type and grade of the installation environment for the electrical equipment, as well as the type of electrical equipment itself.

The explosion protection rating for chemical and electrical equipment depends on the media used in your workshop

I’m talking about why a certain type of explosion-proof equipment cannot be used in factories.

Class I equipment – Equipment used in the underground parts of mines and in the surface facilities of such mines, which can be exposed to hazards caused by methane and/or flammable dusts. Class II equipment – Equipment used in other situations where danger may arise due to an explosive environment. Class II equipment is further subdivided into: Class IIA (propane) ； Class IIB (ethylene) ； Class II C (hydrogen) ； Class II (all gases). Still referring to what was said above, explosion-proof electrical equipment should be selected based on the type and classification of the installation environment for such equipment, as well as the type of electrical equipment itself. Due to differences in the environmental medium, the safety clearance, ignition current, and operating temperature also vary. These factors are taken into account when designing the equipment for explosion protection, which results in structural differences as well.

Using riot-control electrical equipment in ordinary places is too extravagant; it’s fine to use it without regard for costs
