The Zhundong-Huainan 1100 kV (DC) transmission line project is the longest and highest voltage transmission line ever built. CTC Global’s authorized manufacturing partner NARI Huaisheng Power Cable Ltd provided 291 kilometers of ACCC® Conductor for the project with ACCC Core manufactured by CTC Global’s core production facility in China. The ACCC Conductor supplied was used for the critical grounding line from the DC neutral busbar at the Guqiuan 1100 kV DC/AC converter station.  

The west-to-east ultra-high-voltage (UHV) DC power transmission line, over 3,300 kilometers long, passes through China’s Xinjiang, Gansu, Ningxia, Shaanxi, Henan and Anhui provinces. The new line is capable of delivering 66 billion kilowatt-hours of electricity to eastern China, annually.

CTC Global’s manufacturing facility in China is fully operational and continues to produce ACCC Core for the Chinese market. A China Central Television CCTV news video can be found at this LINK
