The project has a total length of 143km and a total investment of 282 million yuan. And 1/4”split conductor (cross section 400 mm2) is adopted in single and double circuits. Its ultimate transmission capacity is 2,920MVA. The transmission line starts from 500kV substation of Houshi Power Plant and terminates at Quanzhou 500kV Substation, running through Zhangzhou, Xiamen and Quanzhou. The completion of the project has ensured the safe and stable power supply of 7×600MW Houshi Power Plant and improved the safe and stable operation of Fujian power grid and its capability of power transmission to East China power grid.
