HVDC Gezhouba – Shanghai
The Gezhouba – Shanghai HVDC line is the first long-distance HVDC transmission line in China. It leads from the converter station at the Gezhouba dam to the converter station at Nanqiao near Shanghai . The 1046 km long bipolar 500 kV line, built from 1985 to 1989, can transmit a maximum output of 1200 MW .
Between 2008 and 2011, the masts between Fenjing and Liufangtei , which were designed for two conductor cables and were mainly designed as cable-tensioned structures, were replaced by free-standing masts for four conductor cables to also accommodate the circuits of the 500 kV HVDC line built during this period Hubei- Shanghai, which has a transmission capacity of 3000 MW.
The grounding electrode at Chujiahu is also used by the HVDC Dreischluchtendamm – Changzhou .
