Junction box series: The shell is made of impact-resistant glass fiber reinforced polyester material, all metal parts are corrosion resistant. The joint surface of the lid and the base is designed to bump-shaped structure with silicone rubber seal to ensure IP65 degree of protection. As a sub-line voltage 220V/380V line connecting a variety of electrical equipment and instrumentation, wiring purposes. Existing junction boxes in three sizes: 2.5-3.5 mm square interior spiral self-locking terminal block specifications, will introduce the wire fixed connection. The specifications of different models of cable glands meet different cable lead: plastic cable gland entry (installed end) is a metric thread, the inner fortification loose jaws, with good mechanical characteristics. Unused cable entry available empty plug plug seal, more convenient facilities for future modifications and extensions. Scope 1.1 zone, Zone 2 hazardous gas spaces; Ⅱ A, Ⅱ B, Ⅱ C class T1-T5 group explosive gas or vapor environment; 3. Indoor and outdoor (IP54, IP65 * When ordering, need to put forward). Technical characteristics. Proof junction box 380V following circuit, as a variety of electrical equipment wiring division line. 2. Material glass fiber unsaturated resin, stainless steel, aluminum alloy shell, surface coating, beautiful appearance. 3. Explosion-proof junction boxes labyrinth seal structure, waterproof and dustproof effect. 4. modular structure, the number of terminals, the direction of the inlet and outlet, an unlimited number of users can meet various requirements. 5 steel tube or cable wiring. 6. explosion-proof junction box in accordance with GB3836-2000, IEC60079, GB12476.1-2000, IEC61241 standard requirements
