Proof junction box is a variety of specialized equipment used in high-risk areas, and civilian junction box ratio, which is the result of a variety of explosion-proof function has transformed from a junction box. Die-cast aluminum or stainless steel welding, explosion-proof junction box by category are: material according to function into the form: The 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: Wall-mounted vertical explosion proof junction boxes and junction boxes. Proof junction box series: shell impact-resistant glass-fiber reinforced polyester material, all metal parts are corrosion resistant. Cover and base designed concave-convex joint surface with silicone rubber seal structure to ensure a degree of protection IP65. As the voltage 220V/380V lines connecting various electrical equipment and instrumentation for sub-lines, wiring purposes. Junction boxes available in three sizes: built-in self-locking screw terminals specifications 2.5-3.5 mm, the introduction of a fixed wire connection. Specifications of different models to meet different cable gland cable entry: molded cable gland entry (mounting end) is a metric thread, the inner fortification loose jaws, with good mechanical characteristics. Unused cable entry plugs plug sealing the space available, more convenient facilities for future retrofit and expansion. Scope 1.1 Zone 2 hazardous gas areas; 2. Ⅱ A, Ⅱ B, Ⅱ C Class T1-T5 group explosive gas or vapor; 3. Indoor and outdoor (IP54, IP65 * be made when ordering). Technical Features 1. Proof junction box at 380V the following circuit, as a variety of electrical equipment wiring, sub-lines. 2. Material unsaturated polyester resin with glass fiber, stainless steel, cast aluminum housing, surface coating, beautiful appearance 3. Explosion junction box with labyrinth seal structure, waterproof and dustproof effect. 4 using modular structure, the number of terminals, inlet and outlet direction, not the number, users can meet various requirements. 5. pipe or cable wiring. 6. Explosion junction boxes comply with GB3836-2000, IEC60079, GB12476.1-2000, IEC61241 standard request.
