The explosion-proof distribution box for factories mainly includes a lighting distribution box for controlling the lighting system and a power box for controlling the power system.
Second, explosion-proof distribution box classification
2.1 Integral and modular box structure, most of the structure of this type of product is modular, can control a number of loops 2.2 box material cast aluminum die-casting and steel plate welding, there are a small part of the insulating material shell (engineering plastics) .
Third, explosion-proof distribution box configuration
Explosion-proof power distribution box is mainly composed of circuit breakers, contactors, thermal relays, transfer switches, signal lamps, buttons and other components. During actual production, it is customized according to the needs of users and the on-site construction drawings. Component brands are concentrated in ABB, Schneider, and Chint.
After more than ten years of technology accumulation and precipitation, Shanghai Baolin Explosion-proof Electric Appliance Co., Ltd. has a wealth of experience in the design, production and maintenance of explosion-proof distribution boxes. It is a well-known brand in the explosion-proof electrical industry, and is the first and only company in the industry. "Factory explosion-proof electrical service demonstration unit." The BXM(D) series of explosion-proof lighting (power) distribution boxes produced by Shanghai Baolin Explosion-proof Electric Appliance Co., Ltd. can be used in explosive gas environments in Zones 1 and 2 and in flammable dust environments in Zones 21 and 22, and the enclosures are made of copper-free aluminum. Alloy die-casting or steel plate welding, modular structure, appearance of high-pressure electrostatic spray, with high corrosion resistance. The highest explosion-proof mark is IICT6, which can be made into explosion-proof type d, compound type de, shell protection type tD (dust) structure, the product has been tested by the national authorized authority inspection agency, issued explosion-proof certificate, and after low temperature test, it can be at ambient temperature. -40°C~+40°C. The maximum current of the main circuit of the explosion-proof distribution box can reach 400A and the maximum voltage can reach 690V, which can meet most of the circuit control requirements for factories. Relying on a strong after-sales service platform - Yi Weibao, to provide customers with better services. "Bao Explosion-proof, everything is more safe!"
