Non-standard explosion-proof lighting distribution box models

Non-standard explosion-proof lighting distribution boxes, such as the LiaoHe BXD (M) Series, offer customizable configurations for hazardous environments, ensuring safety, durability, and compliance with industrial requirements.

Overview of Non-Standard Models

Non-standard explosion-proof distribution boxes are designed for hazardous zones where explosive gases, dust, or moisture may be present. These models provide customized solutions beyond standard configurations, allowing industries to tailor the box to specific voltage, circuit, and installation requirements . They are widely used in chemical plants, oil refineries, mining operations, and other industrial facilities.

Key Features

• Construction Materials: Typically made from cast aluminum alloy or 8050 material, with electrostatic spraying for corrosion resistance, high strength, and impact resistance .
• Explosion-Proof Design: Component cavities use flameproof structures, while bus and inlet/outlet cavities adopt increased safety designs. Sealed contact surfaces with gaskets ensure explosion-proof and airtight performance .
• Circuit Protection: Equipped with miniature circuit breakers for standard loads and NSX series molded case circuit breakers for high current, including overload, short circuit, leakage, auxiliary, separation, and alarm modules .
• Customization Options: Non-standard models allow personalized configurations for rated current, inlet/outlet types, number of circuits, and protection levels, accommodating unique industrial needs .

Examples of Non-Standard Models

• LiaoHe BXD (M) Series: Composite type with flameproof and increased safety cavities, suitable for lighting and power control in hazardous zones .
• PXT (R)K-X/X-X/X-X/X-IPX Series: Surface-mounted or concealed distribution boxes with customizable wiring methods, rated currents, inlet styles, and main switch types .
• AGP17 Series: Explosion-protected distribution boards for MCB distribution of lighting, heating, and socket circuits, available in GRP or stainless steel enclosures, suitable for offshore or corrosive environments .

Installation and Application

Non-standard boxes can be installed vertically, hanging, concealed, or exposed, depending on site requirements. They support 220V or 380V systems and are suitable for Zone 1, 2, 21, and 22 hazardous areas . These boxes are ideal for industrial lighting, power distribution, and control circuits in environments with high risk of explosion or corrosion.

Summary

Non-standard explosion-proof lighting distribution boxes provide flexibility, safety, and durability for hazardous industrial applications. By offering customizable materials, circuit configurations, and installation options, models like the LiaoHe BXD (M) Series and PXT series ensure reliable power and lighting distribution while meeting stringent safety standards .
