Shenhai sprādziendrošas
Class C offers enhanced safety with more meticulous explosion-proof treatment.
| Elektrisko iekārtu temperatūras grupa | Maksimālā pieļaujamā elektroiekārtu virsmas temperatūra (℃) | Gāzes/tvaiku aizdegšanās temperatūra (℃) | Piemērojamie ierīces temperatūras līmeņi |
|---|---|---|---|
| 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. Ūdeņradis, acetilēns, and carbon disulfide necessitate the use of IIC class, whereas other substances are adequately served by IIB class.
