柜式母线槽是高层建筑电气施工的一种新方法,目前已在上海雁荡公寓中采用。过去,国内高层建筑的电气工程,都采用电力纵向干线,电缆垂直敷设,树干式供电,分层每户设置量电表计。这种方法施工量大,施工难度也大,须将全部电缆运至顶部再垂直下放。因电缆自重较大,在施工中稍不当心,就会造成电缆内部的机械损伤,从而造成隐患,难以保证质量。用这种方法施工,工期较长,因主体结构 The trunk busway is a new method of electrical construction for high-rise buildings and is currently used in Shanghai Yandang Apartments. In the past, the electrical engineering of high-rise buildings in China has adopted vertical trunk lines, vertical cable laying, trunk-type power supply, and hierarchical metering for each household. This method has a large amount of construction and is difficult to construct. It is necessary to transport all the cables to the top and then to lower them vertically. Due to the large weight of the cable, a little care in the construction will cause mechanical damage inside the cable, causing hidden dangers and difficulty in ensuring quality. With this method of construction, the construction period is longer due to the main structure
