Explosion-proof junction box is an explosion-proof product for wiring used in special hazardous environments. There are terminal blocks in the explosion-proof junction box. Explosion-proof junction boxes are divided into IIB grade and IIC grade according to the explosion-proof grade. Explosion-proof junction boxes are generally divided into straight-through, tee, cross, angle, etc. according to the number of heads; if they are classified according to the appearance of the top cover, explosion-proof junction boxes are divided into There are two types of explosion-proof junction box with flat cover and explosion-proof junction box with hanging cover.
Explosion-proof junction boxes are used in explosion-proof areas, mainly for houses, frame structures, and when cables change direction. The explosion-proof junction box is used for the connection of the conduit and the flexible pipe is used for the connection between the conduit and the surface. When the explosion-proof junction box is connected to the local surface such as thermocouple, thermal resistance, transmitter, etc., metal hose or flexible connection should be used as protection tube. The bend of the explosion-proof junction box is generally made of elbows. When each two 90 degree elbows or the straight line length of the threading pipe exceeds 30m, an explosion-proof junction box should be installed.
In fact, many customers can't tell the difference between explosion-proof junction boxes, explosion-proof threading boxes, and explosion-proof junction boxes. The editor of explosion-proof junction box manufacturers is here to explain the role of explosion-proof junction boxes for us: Explosion-proof junction boxes, explosion-proof threading boxes There are also explosion-proof junction boxes that are used for the interface of the line when connecting the wires during decoration, but the three have their own uses. Let me talk about the differences in the use of the three. 1, the role of explosion-proof junction box; explosion-proof junction box is used to connect the nanowires and equipment or devices, as well as the transition between light and dark pipelines and the transition between rigidity and flexibility. 2. The role of the explosion-proof junction box; the explosion-proof threading box is when the laying length of the line pipeline exceeds a certain limit, perhaps the line is divergent, or the line has too many bends, when the whole pipe is not easy to thread, this is at the base You need to add a box, this box is the explosion-proof junction box. 3. The role of the explosion-proof junction box; the explosion-proof junction box is the place where power distribution, electrical equipment and external lines are connected. This place needs a device to protect the line, and a box will be added in this place for protection. There are generally limited terminal blocks in the interior, or there may be no terminals but there are connection ends of switching devices. Under normal circumstances, this connection device can be disassembled.
