Shenhai Explosion-Proof
Miturut standar nasional kanggo proteksi bledosan listrik, BT4 lan BT6 kalebu ing Kelas IIB.
| Klompok suhu peralatan listrik | Suhu lumahing maksimum sing diijini saka peralatan listrik (℃) | Suhu nyala gas/uap (℃) | Tingkat suhu piranti sing ditrapake |
|---|---|---|---|
| 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 |
Nanging, the ‘T’ classification pertains to the temperature rating of explosion-proof electrical devices. Piranti sing diklasifikasikake minangka T6 kudu njaga suhu permukaan ora luwih saka 85°C, T5 kudu ora ngluwihi 100 ° C, and T4 must not surpass 135°C.
The lower a device’s maximum surface suhu, the less likely it is to ignite atmospheric gases, thereby enhancing safety. Akibate, the explosion-proof rating of BT6 exceeds that of BT4.
