Abstract: According to "Code for Design of Electrical Installations in Explosion and Fire Hazardous Environments", of course, T6 is the safest. T6 grade, the ignition temperature is the lowest, such explosion-proof lamps can also effectively prevent explosions for combustible gases with low ignition points, and of course there are no problems with combustible gases with high ignition points.
Explosion-proof lamps are used in temperature groups T1~T6 in explosive gas environments, which is the safest?
Explosion-proof lamps first clarify two points:
1. The temperature group of explosion-proof lamps T6 is the highest, and T1 is the lowest.
2. Generally speaking, explosion-proof lamps are not afraid of damage to the internal components of the explosion-proof lamps themselves, but to limit the energy released from the damage of the internal components of the explosion-proof lamps to not cause gas explosions in explosive environments. We see that the name of T6 is written as "maximum surface temperature". The maximum surface temperature refers to the highest surface temperature that the explosion-proof lighting element in the explosion-proof lamp itself can reach no matter what state it is in, so the lower the better, the higher the temperature. The higher the danger, the higher the T6 than the T1 according to this interpretation. According to the "Code for Design of Electrical Installations in Explosion and Fire Hazardous Environments", of course, T6 is the safest. T6 grade, the ignition temperature is the lowest, such explosion-proof lamps can also effectively prevent explosions for combustible gases with low ignition points, and of course there are no problems with combustible gases with high ignition points.
