Shenhai a proba de explosión
Class C offers enhanced safety with more meticulous explosion-proof treatment.
| Grupo de temperatura dos equipos eléctricos | Temperatura máxima admisible da superficie dos equipos eléctricos (℃) | Temperatura de ignición de gas/vapor (℃) | Niveis de temperatura aplicables ao dispositivo |
|---|---|---|---|
| T1 | 450 | > 450 | T1 ~ T6 |
| T2 | 300 | > 300 | T2 ~ T6 |
| T3 | 200 | > 200 | T3 ~ T6 |
| T4 | 135 | > 135 | T4 ~ T6 |
| T5 | 100 | > 100 | T5 ~ T6 |
| T6 | 85 | > 85 | T6 |
Flameproof designs typically feature threading rather than insertable components. Class C devices provide longer flameproof surfaces and narrower explosion gaps. Hidróxeno, acetileno, and carbon disulfide necessitate the use of IIC class, whereas other substances are adequately served by IIB class.
