Low voltage loss: Due to the low resistivity of copper core cables, the same current flows through the same cross section. The voltage drop of copper core cable is small. The same transmission distance, can ensure higher voltage quality; in the allowable voltage drop conditions, copper core cable transmission can reach a longer distance, that is, the power supply covers a large area, which is conducive to the planning of the network, reducing the number of power supply points set up.

The project is planned to construct two data center server room buildings with a floor area of about 45,000 square meters. Upon completion, over 6,000 high-density cabinets will be provided. The project is expected to be gradually delivered and put into operation from 2021 onwards and will be operated and managed by the data center operator, Shenzhen Huateng Intelligent Technology Company Limited, in accordance with Keppel Data Center's global operational specifications. In addition, the data center site can also add another approximately 50,000 square meters of floor area, bringing the total floor area to approximately 95,000 square meters.

Aluminum alloy cable in China has not been applied for a long time but there have been cases showing that aluminum alloy cable applications in cities and factories and mines have huge hidden dangers and risks, the following two actual cases and the eight factors that lead to risky accidents of aluminum alloy cables are discussed.

In the engineering design documents are usually generalized cable tray called “bridge”, did not point out the specific structural features, different types, different production materials, cable tray price difference is large, and the structure of the type of confusion will bring about the work site heat dissipation, mechanical protection problems. Therefore, at the design stage, designers should be required to choose the structural characteristics of cable trays according to the characteristics of the project environment and technical requirements, and clearly express them in the model labeling and material table of the plan.
