BXJ1 series explosion proof junction box junction box is a special device used by a variety of high-risk sites, and civil junction box ratio, which is the result of the transformation from a variety of explosion-proof junction box has a function. Die-cast aluminum or stainless steel welding, explosion-proof junction box by category are: Material according to function into the form: intrinsically safe explosion-proof junction box, aluminum explosion-proof junction box, stainless steel explosion-proof junction box, steel explosion-proof junction box; Depending on the structure is divided into: a wall-mounted vertical explosion-proof junction boxes and junction boxes. Explosion-proof junction box series: shell with impact-resistant glass fiber reinforced polyester material made of all metal parts are corrosion-resistant. Combination of surface cover and base are designed to convex shape with silicone rubber seal structure to ensure the IP65 degree of protection. As the connection of various electrical equipment and instrumentation in the voltage 220V / 380V line point line, wiring purposes. Existing junction boxes in three sizes: built self-locking screw terminals specifications are 2.5-3.5 mm, the introduction of a fixed wire connections. Different models to meet the specifications of the cable gland different cable entry: Plastic cable gland entry system (mounting end) metric thread, fortification loose jaws, with good mechanical characteristics. Unused cable entries available empty plug plug seal, retrofit and expand facilities for the future easier. 2 Detail Cathodic protection is a special explosion-proof junction box terminals according to the new company together in cathodic protection engineering for multiple cables convergence, convergence and other self-designed special double contact with the box, in the petroleum, chemical and other business units explosive Environmental Engineering has been widely promoted and applied. Working conditions altitude does not exceed 3 2000m; ambient air temperature not higher than + 60 ℃, not lower than -40 ℃; air relative humidity less than 90% (+ 20 ℃ when); vertical mounting inclination of not more than 5 °; no significant Local shake and a strong shock and vibration; and no significant damage to the metal and insulation corrosive gases and vapors environment; no dripping liquid intrusion and elsewhere. 2. ⅡA, ⅡB, ⅡC class T1-T5 group explosive gas or vapor;; range 4 applies 1.1 Zone 2 hazardous gas areas combustible dust 3. 20, Zone 21 and Zone 22 4. Indoor outdoor (IP54, IP65 * to be mentioned when ordering). 5 Technical Features 1. proof junction box at 380V following circuit, as a variety of electrical wiring devices, sub-line use. 2. Material fiberglass unsaturated resin, stainless steel, cast aluminum housing, surface coating, beautiful appearance. 3. explosion-proof junction box with labyrinth seal structure, good water and dust effects. 4. Using a modular structure, the number of terminals, inlet and outlet directions and number to meet user requirements. 5. Pipe or cable wiring. 6. explosion-proof junction boxes meet the GB3836-2000, IEC60079, GB12476.1-2000, IEC61241 standards. Installation and maintenance of the first 6 1. Installation should check the technical data on the nameplate match the actual usage; 2. Check all fasteners are loose phenomenon, if loose should be tightened; 3. junction box inside and outside the ground must good and reliable; 4. need to install cables through seals, metal gaskets, compression nut with compression, guarantee seal and not loose cables, wiring port does not use metal shims to apply seals and sealing; 5. After opening the cover before you must disconnect power during maintenance checks; 8 Ordering Information Order should include full junction box complete model, name, size and number of orders. Example: BJX-20/30-proof junction boxes, terminal number 20, rated current of 30A, the top line, Inlet thread 1 * G20,1 months, outlet below the outlet thread 2 * G15,4 months. 50 optional wall-mounted and floor-standing, etc.
