Fixed Explosion-proof Distribution Box Model

Fixed explosion-proof distribution boxes include models such as GGD, GDH, PGL, and CZ1290, designed for safe electrical distribution in hazardous environments.Common Fixed ModelsGGD, GDH, PGL Series: These are low-voltage fixed switchgear cabinets suitable for industrial power distribution. They are designed for permanent installation and can handle various rated currents and short-time withstand currents, typically in 220V or 380V systems. They are often made of metal for durability and flame resistance and can include multiple outlet circuits and main switch types with IP30 or higher protection levels .CZ1290 Series: A modular fixed explosion-proof distribution box widely used in petrochemical, medical, food processing, aerospace, and military applications. It features modular design, completed internal wiring, and external operating handles for easy operation. CZ1290 boxes are exported globally and can be customized to meet specific project requirements .HRMD92 Series: Stainless steel flameproof enclosures (Ex d IIB+H2) suitable for feed distribution, control boxes, terminal boxes, and motor starting boxes. These boxes support a wide range of electrical components, including MCCBs, MCBs, contactors, relays, meters, PLCs, and surge protectors. They are designed for space-saving modular installation and long service life .Key FeaturesMaterials: Metal (steel, stainless steel) or flame-retardant plastic for durability and explosion resistance.Installation: Fixed installation, either surface-mounted or embedded, with options for vertical or hanging setups.Voltage Levels: Typically 220V or 380V, with rated currents and short-time withstand currents customizable.Protection Standards: Compliant with IECEx, ATEX, and other international explosion-proof certifications for Zone 1 and Zone 2 hazardous areas .Modularity: Many models allow combination and expansion to meet complex distribution requirements.Internal Components: Can include main switches, branch switches, circuit breakers, meters, relays, contactors, and control devices.ApplicationsFixed explosion-proof distribution boxes are used in industrial plants, chemical processing, oil and gas facilities, construction sites, and other hazardous environments where electrical safety and explosion prevention are critical. They ensure reliable power distribution while protecting personnel and equipment from sparks or electrical faults. These models provide flexibility, safety, and compliance with international standards, making them suitable for both standard and customized industrial electrical systems .
