2. Exd Class II: Shell type explosion-proof lamp. Suitable for environments containing flammable gases, steam, or mist, such as petrochemical, light industry, pharmaceutical, shipbuilding, and other industries.

3. Exd II Class A: Suitable for linear shaped lighting places such as pipelines, it can prevent sparks from flying out or electric arcs from penetrating pipelines.

4. Exd Class IIB: Suitable for places with flammable gases such as hydrogen, acetylene, and epoxy.

5. Exd Class IIC: Suitable for workplaces containing methane or flammable gases such as petroleum and coal mines.

6. Exe: Non explosive explosion-proof lamp. Used in lower hazardous environments, such as processing materials, construction services, etc.

7. ExnA: Non spark friction explosion-proof lamp. Suitable for damp and corrosive environments such as pulping, papermaking, and food.
