Project Overview
The Shenzhen Airport Ground Transportation Center is a large-scale transit hub integrating rail, bus and passenger facilities in Shenzhen, Guangdong, China. As part of the electrical infrastructure for this project, Shenzhen Wanan Industrial Co., Ltd. supplied cable tray systems for the facility's power and data cable management network.
Location: Shenzhen, Guangdong, China
Project Type: Airport & Transportation Infrastructure
Application: Electrical Cable Management
Products Supplied: Cable Tray, HDG
Supplier: Shenzhen Wanan Industrial Co., Ltd.
Project Requirements
Transportation hub projects like this one place several specific demands on cable tray systems:
High cable volume and mixed cable types — power, lighting, communication and control cables often run in parallel across the same routes, requiring trays with enough capacity and, in some sections, physical separation between circuits.
Long spans and heavy structural loads — ceiling heights and support spacing in transit facilities are often wider than in typical commercial buildings, so tray load capacity and deflection under full cable load needed to meet design tolerances.
Corrosion resistance for a coastal, high-humidity climate — Shenzhen's climate requires coatings that hold up over the long service life expected of public infrastructure.
Compliance with fire safety and public infrastructure codes — cable management in public transportation facilities is subject to strict safety and certification requirements.
Solution
To meet these requirements, Wanan supplied hot-dip galvanized perforated cable tray and ladder-type cable tray sized for the project's cable loads and support spacing.
Key aspects of the solution included:
HDG coating meeting corrosion resistance requirements for coastal climates
Reinforced side rails for spans of X meters between supports
Perforated tray sections for ventilation and cable visibility, combined with solid-bottom or covered sections where separation was required
Results
The cable tray systems were installed as part of the facility's electrical infrastructure, supporting the project's power and data cable routing across the transportation center.
Why This Project Matters for EPC Contractors and Developers
Large transportation infrastructure projects require cable tray suppliers who can deliver consistent quality at scale, meet coastal-climate corrosion resistance standards, and support fast-track project timelines. Wanan's 22+ years of manufacturing experience and in-house production capacity make it possible to supply projects of this scale directly from the factory, with technical support throughout the design and installation phase.
FAQ
Q: What type of cable tray is best suited for airport and transportation infrastructure projects?
A: Hot-dip galvanized (HDG) or ZAM-coated perforated and ladder-type cable trays are commonly used, chosen for their corrosion resistance, load capacity and long service life in high-traffic public infrastructure.
Q: How is cable tray load capacity determined for large infrastructure projects?
A: Load capacity is calculated based on span length between supports, tray width and depth, and the total weight of cables to be carried, following standards such as IEC 61537 or NEMA VE 1.
Q: Does Wanan provide custom cable tray solutions for large-scale projects?
A: Yes. Wanan offers OEM/ODM services and can customize tray dimensions, coatings and accessories to match specific project requirements.
