Explosion-proof junction box junction box is the use of die-cast aluminum or stainless steel welded, explosion-proof junction box category have the explosion-proof junction box, aluminum stainless steel explosion-proof junction box junction boxes, steel welding explosion-proof junction box, junction box into stand type and hanging two kinds. , Durable, easy to use; for the next petroleum, chemical and other business units explosive atmospheres, as a telephone cable connections and sub-line use. Explosion-proof junction box: 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 bump shape with silicone rubber seal structure to ensure the IP65 protection rating. As the connection of various electrical equipment and instrumentation in voltage 220V / 380V line point line, wiring purposes. Existing junction box in three sizes: built self-locking screw terminals specifications 2.5-3.5 mm, the introduction of a fixed wire connection. Different types and specifications of cable glands meet different cable entry: Plastic cable gland entry system metric thread, loose jaws armed with good mechanical characteristics. Unused cable entries available space plug plug seal, 2 working conditions working conditions Altitude does not exceed 2000m; ambient air temperature not higher than + 60 ℃, not lower than -40 ℃; air relative humidity less than 90% (+ 20 ℃ time); vertical mounting inclination of not more than 5 °; no significant shake and shock vibration of strong local; no significant damage to the metal and insulation corrosive gases and vapors environments; no dripping water and other liquids as invasive. Scope 1.1 Zone 2 hazardous gas areas; 2. ⅡA, ⅡB, ⅡC class T1-T5 group explosive gas or vapor; 3. combustible dust Zone 20, 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 the variety of electrical wiring devices, sub-line use. 2. Material glass fiber unsaturated resin, stainless steel, cast aluminum housing, surface coating, appearance. 3. proof junction box with labyrinth seal structure, good waterproof and dustproof effects. The modular structure, the number of terminals, inlet and outlet directions and number to meet user requirements. 5. Pipe or cable wiring. Caution Pre-installation should check whether the technical data on the nameplate correspond with the actual use; 2. Check all fasteners are loosening, if loose should be tightened; 3. junction box inside and outside the ground must be good and reliable; 4 When installing the necessary cables through the seals, metal gaskets with compression nut pressing, ensure the seal and the cable must not loose connection port applications without the use of seals and metal gaskets to be blocking; 5. maintenance and inspection must After disconnect the power before opening the lid; the ever-changing customer products can communicate with the staff and then determine how to do good
