The Use of Explosion Proof Lamp 

The principle of flameproof type is based on the European scale EN13463-1:2002 "Explosive environment with non-electrical equipment part 1: Fundamental method and request" explosion-proof concept and fire type, flameproof type is used to permit internal explosion and block the flame transmission of an explosion-proof type, is the most commonly used explosion-proof type.  Because this explosion-proof type of lamp shell is generally made of metal material, good heat dissipation, high strength and good durability of the shell, very popular with users.  

Moreover, many safety explosion-proof lamp parts, such as lamp holder, interlock switch, also take flameproof structure.  Electrical equipment with flameproof enclosure is called flameproof electrical equipment.  If the explosive gas mixture enters the flameproof enclosure and ignites, the flameproof enclosure can suffer the explosive pressure of the internal explosive gas mixture and prevent the internal explosion from spreading to the explosive mixture around the enclosure.  This is a gap explosion-proof principle, that is, the application of metal gap can block the spread of the explosion flame and cool the temperature of the explosion product, reach the flame extinguishing and cooling, the principle of restraining the expansion of the explosion design of a structure.

Applicable to explosive gas environment zone 1, zone 2 dangerous occasions;  Applicable to IIA, IIB, IIC explosive gas environment;  Applicable to combustible dust environment 20, 21, 22 zone;  Suitable for the temperature class T1 - T6 environment.
