2. Project Background & Industry Pain Points

As a benchmark global exhibition for entertainment technology, Prolight + Sound Frankfurt imposes far stricter requirements on temporary power support than ordinary industrial exhibitions. The extreme construction schedule and complex power operating conditions expose prominent defects in traditional power distribution solutions, which are mainly reflected in five aspects:

2.1 Ultra-Short Construction Cycle Restricts Traditional Wiring Modes

The entire booth construction and dismantling cycle of international exhibitions is highly compressed, with only 36 to 48 hours for full build-up and 12 to 24 hours for complete dismantling. Traditional on-site wiring requires electricians to complete wiring, debugging and testing point by point, which involves cumbersome procedures and long construction cycles, failing to meet rapid deployment demands. In addition, European local electrician resources are scarce with high overtime labor costs, and traditional construction methods easily lead to schedule delays and excessive construction expenses.

2.2 High-Density High-Power Loads Require Strict Voltage Stability

Lighting and audio exhibition booths are equipped with high-power LED walls, moving-head stage lights, power amplifier arrays and dimming equipment, with a single regional peak load up to 60kW. Frequent equipment start-stop and fluctuating loads place high demands on power supply stability. Minor voltage drops or transient electromagnetic interference will directly cause LED screen flicker and audio noise distortion, seriously undermining the booth’s display effect and professional presentation.

2.3 Indoor and Outdoor Mixed Scenarios Bring Higher Environmental Protection Requirements

The exhibition covers both indoor halls and outdoor power connection areas. Frankfurt experiences frequent rainfall in April, requiring excellent waterproof performance for outdoor electrical equipment. Meanwhile, indoor construction and dismantling processes generate massive dust, which puts forward high dustproof requirements for indoor power distribution devices. Most conventional power products are only applicable to single scenarios, requiring separate equipment inventory for indoor and outdoor use, resulting in low equipment reuse rates and increased inventory management costs for construction contractors.

2.4 Crowded Exhibition Venues Impose Strict Safety & Compliance Supervision

The exhibition receives an average daily visitor flow of over 50,000 people, mandating reliable leakage protection and comprehensive safety precautions for all temporary power distribution points. European exhibition authorities have standardized and rigorous electrical acceptance procedures, requiring complete technical documents and inspection certificates. Missing documents or non-compliant equipment will directly delay power approval and affect on-time booth delivery.

2.5 Grid Connection of Multiple Devices Causes Complex Power Quality Problems

Modern exhibition booths integrate LED display systems, intelligent lighting, digital signage and professional audio devices on a single power distribution network. The parallel operation of multiple electrical devices produces non-linear loads and instantaneous inrush current, easily triggering harmonic interference and transient overloads. Ordinary power distribution equipment lacks anti-interference and overload resistance, prone to false tripping and abnormal equipment operation, and cannot meet the high-stability power demand of premium exhibitions.
