上海拆除部分悬空电缆排除隐患 保障进口博览会安全 - 2018年09月27日

Overhead cables on eight roads near the venue for the upcoming import expo in Qingpu District have been removed, State Grid Shanghai said on Wednesday.
A total of 51 kilometers of cables and 578 street poles were removed in the past six months, it said.
Removing the cables involved a series of designs from pipeline routing to site selection of transformer substations. Complicated communication, water and gas pipelines buried underground around the National Exhibition and Convention Center made the project even more difficult. The fact that Metro Line 17 runs under Songze Avenue, one of the eight roads, also added difficulties for the city’s power company.
