摘要
上海长江大桥、隧道内敷设的电力电缆是目前国内在桥梁及市政隧道内敷设的最长220kV高压电缆。介绍了该工程电缆通道的设计、电缆选型,在隧道、桥梁这两种特殊敷设环境下,应对伸缩、桥梁振动的措施及对周围其他电缆的影响等方面内容,可供国内其他类似工程借鉴。
The power cable laying in Shanghai changjiang bridge and tunnel project is the longest 220 kV cable among that laid in the municipal tunnels and on the bridges in China. The paper introduces the main philosophy of the cable channel design,cable type selection, and layout of the cable on the bridge and in the tunnel, as well as the special technologies to deal with the extension, vibration of the bridge and the impacts to other cables. It provides the reference for other similar projects in the future.
