Shenhai-Proof Shpërthimi
Class C offers enhanced safety with more meticulous explosion-proof treatment.
| Grupi i temperaturës së pajisjeve elektrike | Temperatura maksimale e lejuar e sipërfaqes së pajisjeve elektrike (℃) | Temperatura e ndezjes së gazit/avullit (℃) | Nivelet e aplikueshme të temperaturës së pajisjes |
|---|---|---|---|
| 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. Hidrogjeni, acetilen, and carbon disulfide necessitate the use of IIC class, whereas other substances are adequately served by IIB class.
