Dimensions and Specifications of the Power Distribution Box in the Exhibition Hall

Exhibition hall power distribution boxes are robust, modular units designed for high-power booth applications, featuring IP66 protection, 125A industrial sockets, and separate strong/weak current compartments.

Structural Design and Materials

The boxes typically have a bearing frame made of cold-formed rectangular welded steel pipe, providing high mechanical strength and stability. The casing cover is constructed from 10 mm thick stainless steel 304 or high-quality tread plate, with surface treatments such as wire drawing or high-strength wear-resistant paint to withstand mechanical pressure from wheels and equipment . The enclosure is designed to separate strong and weak current wiring, reducing electromagnetic interference and allowing independent maintenance of weak current boxes .

Electrical Specifications

• Sockets: Equipped with 125A high-power industrial connector sockets, installed on both sides of the box and inclined for easier plug-in and pull-out .
• Protection: Circuit breakers, residual current devices (RCDs), and surge protectors are installed in separate compartments to prevent dust, moisture, and water ingress, achieving IP66 protection .
• Power Capacity: Some models, such as those from CUBE Technologies, support single-phase or three-phase distribution up to 22 kW, suitable for high-demand exhibition equipment .

Safety and Operational Features

• Locking Mechanisms: Covers for the power control box and outlets are equipped with special locks and mechanical self-locking braces to prevent unauthorized access and ensure safe operation .
• Modularity: Weak current boxes can be assembled or disassembled separately, allowing flexible installation and maintenance without affecting strong current circuits .
• Durability: The enclosure is often rotomoulded polyethylene or steel, with microblasted and flamed surfaces for scratch resistance and edge hardening .

Additional Considerations

• Mounting: Designed for easy installation even in confined spaces, with robust mounting brackets .
• Data Monitoring: Some boxes can include multifunction meters for recording electricity consumption and load distribution .
• Customization: Many suppliers offer customizable configurations to meet specific booth layouts and power requirements . These specifications make exhibition hall power distribution boxes highly reliable, safe, and adaptable for temporary or permanent installations in trade shows, conventions, and other indoor event venues.
