ZHONGSHAN D/S RECONSTRUCTION:

The project is to replace the existing secondary substation. The planned building consists of 12 stories aboveground and 1 story underground. The fifth floor and lower are for electrical substations. Floors from 6th to 12th are for the multi-purpose garage. The total floor area is 15,018 m2.
DAAN~ZHONGSHAN 161KV SHIELD TUNNELING:
The total length of the utility line is 1.76 km with a 3.2 m inner diameter. Press-in caisson is used for two working shafts, 28.9 m and 42.5 m deep. There are 18 two-circuit cables with duplicated conductor cables with a total length of 160 m.
It’s the first shield tunnel that passes through the shield tunnel of the MRT with a clear distance of 5.8 meters in Taiwan. The existing substation is rebuilt into a multi-functional substation building. In addition to being used by Taipower, it also provides parking space to the neighborhood and creates a win-win situation. The shield working shaft and shield tunnel, near the Taiwan Railway Tunnel, Taiwan High Speed Rail Tunnel, MRT Station, Metro Tunnel, and Xinsheng Viaduct construction, are challenging.
