Unused cable inlet can be sealed with air plug plug for future more convenient measures to be modified and expanded. Specifically, xirong special explosion-proof junction box is a special terminal box independently designed by Oko Company according to the cathodic protection engineering for multiple cable conjunctions, junctions and other compound contacts, which has been widely popularized and applied in petroleum, chemical and other enterprises in explosive environment engineering.
Installation and maintenance 1. Before installation, check whether the technical data on the nameplate is consistent with the actual use;
2. Check whether all fasteners are loose. If they are loose, tighten them;
3. The internal and external grounding of the junction box must be good and reliable;
4. During installation, pass the cable through the sealing ring, metal washer, and tighten the cable with the clamping nut to ensure that the sealing and cable are not loose. Seal the connection port not in use with the sealing ring and metal gasket.
5. It is necessary to disconnect the power supply before opening the cover during maintenance and inspection;
1. Explosion-proof junction box in the circuit below 380V, as a variety of electrical equipment wiring, dividing line.
2. The material is glass fiber unsaturated resin, stainless steel, cast aluminum alloy shell, surface spraying, beautiful shape.
3. Explosion-proof junction box adopts curved sealing structure, waterproof and dustproof effect is good.
4. Adopt modular structure, the number of terminals, inlet and outlet direction, the number is not limited, can meet the various requirements of users.
5. Steel pipe or cable wiring.
6. Explosion-proof junction box meets gb3836-2000,IEC60079,GB12476.1-2000,IEC61241 standard requirements.
Different types and specifications of cable sealing sleeve are satisfied with different cable introduction: plastic cable sealing sleeve inlet (installation end) is metric thread, internal protection clamping claw, has good mechanical characteristics. As in the voltage 220V/380V line to connect various electrical equipment and instruments of the branch line, wiring. Made of aluminum alloy die-casting or stainless steel welding, explosion-proof and anti-corrosion junction box according to classification: according to the functional material form is divided into: intrinsic safety explosion-proof junction box, aluminum alloy explosion-proof junction box, stainless steel explosion-proof junction box, explosion-proof steel junction box; According to the use of the structure is divided into: wall-mounted explosion-proof junction box and vertical explosion-proof junction box
.

6. Explosion-proof junction box meets gb3836-2000,IEC60079,GB12476.1-2000,IEC61241 standard requirements.
The junction box is available in three sizes: built-in screw self-locking terminals of 2.5-3.5 mm square, which will lead into fixed connections. The joint surface of cover and base is designed to be concave and convex, with a silicone rubber sealing structure, ensuring IP65 protection grade.
Explosion-proof junction box series: the shell is made of impact-resistant glass fiber reinforced polyester material, and all metal parts are corrosion-resistant. Working conditions The altitude shall not exceed 2000m; Nearby air temperature is not higher than +60℃, not lower than -40℃; The relative humidity of air is not greater than 90%(+20℃); Vertical installation inclination is not greater than 5°; Where there is no significant shaking and strong shock vibration; Without significant damage to metal and insulation of corrosive gases and vapors in the environment; A place free of water and other fluids.
Explosion-proof junction box is a special equipment used in various high-risk places. Compared with civil junction box, it is a junction box with explosion-proof function transformed by various explosion-proof.
1. Hazardous gas sites in Zone 1 and Zone 2;
2. Explosive gas or steam environment of class ⅱ A, ⅱ B, ⅱ C group T1-T5;
3. Combustible dust environment Zone 20, 21, 22
4. Indoor and outdoor (IP54, IP65* required when ordering).
