Hua W Guilin Data Center

I. Project Background

The Hua W Data Center located in Guilin is a core digital infrastructure hub in South China. It is responsible for the deployment of enterprise cloud services, the secure storage of government data, and the support of 5G edge computing. It needs to meet the requirements of 24-hour uninterrupted operation, low-latency data transmission, and high security protection. In the computer room, various types of lines such as server power supply cables, cloud data transmission cables, and emergency support cables are gathered. If they are laid out in a disorderly manner, it is easy to cause equipment failure and will greatly increase the difficulty of operation and maintenance. It is urgent to build a standardized and efficient cable management system through professional cable tray engineering to ensure the continuous and stable operation of data services.

Ii. Customer Background

As a globally leading provider of ICT solutions, Hua W has mature technical standards and a strict quality control system in the field of data center construction. The Guilin data center is positioned as a green, low-carbon, and highly reliable regional digital hub. The clear requirements for this cable tray project are as follows: It must meet the load-bearing capacity of high-density cables, achieve the classified and isolated laying of different types of cables, and at the same time have flexible expansion capabilities to ensure that the infrastructure can adapt to the growth needs of digital services in the long term.

Iii. Project Content

1. Customized selection and design: Based on the functional requirements of the server area, data exchange area, and emergency power supply area in the computer room, steel ladder-type cable trays (for the server area, suitable for high-density cables), closed metal trough-type cable trays (for the data exchange area, to prevent signal interference), and fireproof cable trays (for the emergency power supply area, to enhance safety levels) are respectively customized. Optimize the design of the bridge frame layout to avoid other infrastructure in the computer room (such as air conditioning pipelines and fire protection pipelines), reserve 20% expansion space, and adapt to future business upgrades.

2. Precise installation and construction: Strictly follow the design plan for layout and positioning, with deviations controlled within ≤±2mm; The bridge frame brackets are fixed with standard bolts, and the spacing of the brackets is controlled at 1.5 to 2 meters according to the specifications of the bridge frame to ensure overall stability. The joints of the bridge frame are fastened with special connecting pieces, and the gaps are sealed. Grounding treatment should be carried out simultaneously, with a grounding resistance of no more than 4Ω to prevent the risks of static electricity and leakage.

3. Classified laying and marking: Lay cables in accordance with the principle of "separation of strong and weak current, and layering of power cables and signal cables", and use dedicated partitions to separate different types of cables to reduce interference. Both ends of the cable are affixed with identification labels containing the purpose, equipment number and specification, and the information is entered into Huawei's intelligent operation and maintenance system. Clear direction indicators are provided on the outside of the bridge frame, facilitating quick positioning and maintenance.
