II, C, T6, Gb and Exde, II, C, T6, Gb and Exia, II, B, T, 20The explosion proof grade of mobile explosion-proof lamps Exd, II, C, T6, Gb and Exde, II, C, T6, Gb and Exia, II, B, T2, Ga and Exia II, C, T4, Ga, which kind of explosion-proof grade is higher?Please sort out the difference between the known flameproof type and the intrinsically safe type, as well as the meanings of other characters.Request sorting, if it is higher than the de ia level, please focus on the reasons below, thank you! Hope professional explanation!
1 if you look at the actual level of factors, according to the IEC equipment protection level (EPLS) II equipment is divided into the following three grades Ga Gb Gc respectively using 0.1.2 region, so the last Exia IIC T4 Ga mark the highest, generally speaking, explosion proof lamp Ga certification is not easy.
2.ia and de are not two forms at all, in comparison D flameproof, e increased security, if you want to compare, the highest ia. See GB3836.4-2000 for details
