Guangxi’s first nuclear power send-out electric transmission line, a 500 KV line with two circuits from Fangchenggang Nuclear Power Plant to Haigang Transformer Substation in Qinhuangdao, was brought into operation at 7:29 am on Dec 16, marking a new start to Guangxi’s nuclear power construction.
Fangchenggang Nuclear Power Plant began its construction on July 30, 2010, and it was anticipated to start commercial operations in 2015. In order to guarantee a smooth output of electricity, Guangxi Power Grid Corporation started a 500 KV transmission line project to send out nuclear power from Fangchenggang Nuclear Power Plant, with a total length of 350 km and the total construction cost of 864 million yuan ($139.3 million). The transmission line from Fangchenggang Nuclear Power Plant to Haigang Transformer Substation, which played an important role in the whole project, is 27 kilometers long and has 139 tower footings.
Many difficulties occurred since the project started in March, 2013. In particular the Super Typhoon Rammasun and Kalmaegi battered Fangchenggang city this year, increasing the construction difficulty. However, Fangchenggang Electricity Board finally completed the construction of the 500 KV transmission line in October, 2014, through overcoming difficulties in equipment and transportation as well as cooperating with related governments and construction organizations.
The transmission line will greatly enhance the current capacity and strengthen the power grid structure to provide a continuous power supply.
