简析超高层建筑体态对电缆选型的影响

Impact of Super High-rise Building Shape on Cable Selection

在传统电缆选择方法的基础上,针对超高层建筑特点,引入从建筑功能与体态入手的电缆选型理念,通过对高区中压电缆的固定、各区段疏散时间的分析,总结超高层建筑对电缆选型的需求,介绍10 k V悬垂式电缆和矿物绝缘电缆在超高层建筑中的敷设方式及注意事项,建议形成技术规格书以指导设计、招标及施工。

In view of the characteristics of super high-rise buildings and on the basis of conventional cable selection method, the cable selection philosophy relying on building functions and shapes is described. Moreover, by analyzing the fixation of medium-vohage cables in high areas and the evacuation time required for every section, and by summarizing the demands of super high-rise buildings on cable selection, the system of laying and precautions of 10 kV suspension cables and mineral insulated cables in super high-rise buildings are described. It is recommended to develop technical specifications to guide the design, bidding and construction.
