Shenhai a proba de explosión
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.
| Categoría de condición | Clasificación de gases | Gases representativos | Enerxía de chispa de ignición mínima |
|---|---|---|---|
| Baixo A Mina | eu | Metano | 0.280mJ |
| Fábricas Fóra Da Mina | IIA | Propano | 0.180mJ |
| IIB | Etileno | 0.060mJ | |

Aplicabilidade:
CT has the widest range of applicability.
Gas environment:
CT is an explosion-proof rating for acetylene and hidróxeno niveis. 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.
