Shenhai Explosion-Proof
Nyob rau hauv cov khoom tawg-pov thawj khoom, CT6 thiab CT4 denote qhov chaw kub, Tab sis qhov kub ntawm T6 pawg khoom yog tsawg dua uas T4 pawg khoom. T6 pab pawg neeg khoom yog li no suitable rau explosion-proof daim ntawv thov vim lawv sab qhov chaw kub.
Surface Temperature Classes of Electrical Equipment:
| Cov hluav taws xob hluav taws xob | Qhov chaw uas muaj hluav taws xob (°C) | Roj/vapor ignition kub (°C) | Siv ntau ntau yam kub |
|---|---|---|---|
| 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 |
piv txwv li, if the ignition temperature of explosive gases in the environment where a factory’s explosion-proof lighting is used is 100 degrees, then at its worst operating condition, the surface temperature of any part of the lighting should remain below 100 degrees.
Take the example of buying a television; naturally, you would prefer its surface txias to remain low when it’s on. The same principle applies to explosion-proof products: lower operating surface temperatures equate to safer usage. T4 surface temperatures can reach up to 135 degrees, while T6 surface temperatures can go up to 85 degrees. The lower surface temperatures of T6 products make them less likely to ignite explosive gases and demand higher technical specifications for explosion-proof equipment. tshwj xeeb tshaj yog, it’s evident that the explosion-proof rating of CT6 is higher and safer than that of CT4.
