Many users do not know the difference between the explosion-proof junction box, the explosion-proof junction box and the explosion-proof box, and confuse these three things in the process of use. Although these three are all used for the line interface when connecting the wires during the decoration, these three have their own uses and their functions and application ranges are not the same.
Explosion-proof junction box, explosion-proof junction box, explosion-proof threaded box role difference
1, the role of explosion-proof junction box; explosion-proof junction box is the power distribution, electrical equipment and external lines connected to the place, this place requires a device to protect the line, in this place will add a box as a protection, the general internal box There will be a terminal block on the boundary line or a connection terminal without a terminal but with a switching device. Under normal circumstances this connection device can be removed.
2, the role of explosion-proof junction box; explosion-proof junction box is used to connect the pipeline and equipment or devices, there is the transition between light and dark pipelines and rigid and flexible transition.
3, the role of explosion-proof box; explosion-proof box is when the laying of pipeline length exceeds a certain limit, or the line appears to be different, or the line is too many turns, when the whole root canal is not easy to thread, when in the middle Need to add a box, this box is explosion-proof box.
Explosion-proof junction box, explosion-proof junction box, explosion-proof box Scope of application differences
Explosion-proof junction box is a special equipment used in all kinds of high-risk places. Compared with civilian junction box, it is a junction box with explosion-proof function through various explosion-proof transformations. Aluminum alloy die-casting or stainless steel welding.
Explosion-proof junction box applicable scope:
Suitable for explosive gas environments in Zone 1 and Zone 2;
Suitable for flammable dust environments in Zone 20, Zone 21, and Zone 22.
Suitable for IIA, IIB, IIC explosive environment;
Applicable to temperature group T1 ~ T6 environment.
Explosion-proof box Scope:
Suitable for explosive gas environment Zone 1 and Zone 2;
Suitable for IIA, IIB, IIC explosive gas environment;
Suitable for flammable dust environment Zone 20, Zone 21, Zone 22 For temperature groups of T1 ~ T6 environment;
Applicable to explosive hazardous environments such as oil extraction, storage, chemical, pharmaceutical, military and military facilities.
At this point, you must have understood the main differences between the explosion-proof junction box, the explosion-proof junction box, and the explosion-proof box. Do not confuse the selection in the future!
