POWERCHINA-built Angola SK power transmission: pioneer to BRI

The construction team strictly followed the International Electrical Commission (IEC) standards and adhered to the concept of "safety, application, precision, and innovation."

The constructors implemented domestic mature green environmental protection concepts such as "green grid and harmonious construction" in Africa for the first time.

They also promoted and applied six major projects and 12 sub-projects of 10 new technologies in the construction industry, four national key energy-saving and low-carbon technology projects, and 22 "five new" projects in power construction.

It has won four provincial and ministerial level science and technology progress awards, 17 provincial and ministerial leve lQC achievements, 10 utility model patents, and four provincial and ministerial level work methods.

In particular, the project's achievements such as the key technology research of three-split large-section all-aluminum alloy wire tension wire, the key technology research of transformers for power transmission and transformation engineering, the layout of 400 kV power distribution equipment and system technical specifications, and the original large-section power line crimping trolley technology are the first of their kind at home and abroad. Its success will be used to vigorously promote and encourage the domestic electrical equipment manufacturing industry to "go out" and seek out international opportunities.

The project successfully passed five special evaluations and acceptances after completion. The acceptance rate of 29 unit projects reached 100 percent. The technical performance index is better than the national standard of similar projects in China, creating the highest standard of Angola's electric power projects.

The project won the China Electric Power Quality Engineering (Overseas) Award in 2018.

The project has connected the power grid in northern Angola with the national main power grid, and further improved the power structure of the country.

As of Feb 24, the power station has been operating safely for 815 days, with a cumulative power transmission of 513 million kWh, which has greatly promoted regional economic development and improved the livelihood of residents.

The project was highly praised by the local government and citizens.
