Shenhai-Proof Shpërthimi
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.
| Kategoria e gjendjes | Klasifikimi i gazit | Gazet përfaqësuese | Energjia minimale e ndezjes së ndezjes |

Applicability:
CT has the widest range of applicability.
Gas environment:
CT is an explosion-proof rating for acetylene and hidrogjeni 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 niveli i rezistencës ndaj shpërthimit.
