Shenhai Explosion-Proof
Explosion-proof rating:
Explosion-proof equipment with a CT4 rating is classified as Exd IIC T4. BT4 explosion-proof equipment is rated as Exd IIB T4, which is a lower explosion-proof rating than CT4 equipment.
| 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 |
Applicability:
CT has the widest range of applicability.
Gas environment:
CT is an explosion-proof rating for acetylene and hydrogen levels. If there are gases like acetylene or hydrogen in the environment, CT-rated explosion-proof equipment is required. BT-rated equipment is not suitable for acetylene environments and is only considered a moderate explosion-proof level.
