Shenhai Explosion-Proof
Both groups are classified under T5, which specifies that the maximum surface temperature for explosion-proof electrical devices must not exceed 100°C.
| Condition Category | Gas Classification | Representative gases | Minimum Ignition Spark Energy |
|---|---|---|---|
| Under The Mine | I | Methane | 0.280mJ |
| Factories Outside The Mine | IIA | Propane | 0.180mJ |
| IIB | Ethylene | 0.060mJ | |
| IIC | Hydrogen | 0.019mJ |
Explosion-proof standards are categorized into three levels: IIA, IIB, and IIC, with IIC ranking above both IIB and IIA.
Ultimately, CT5 holds a superior explosion-proof classification compared to BT5.
