Being China National AC & DC research and testing base for high voltage and high power,China XD Group has conducted technical exchange and cooperation with international counterparts. The R&D organizations under China XD Group are the members of IEC and CIGRE, they are in charge of the corresponding technical committees in China,such as IEC TC17, IEC TC42,etc.While acting as the international secretariats of IEC TC28.
With our advanced technology, experts, top-ranking testing equipment and abundant experience in manufacturing, China XD Group is working on developing the products for ±800kV UHVDC,1000KV UHVAC system, and has provided the key equipment for the first 1000 kv UHVAC transmission project Jin Dongnan to Jingmen and the first ±800kv UHVDC transmission project Yunnan to Guangzhou in China.
The maximum testing capacity is as below:
High current test: 21kA power frequency current for long-term temperature rise test, 140kA rated short-time withstand current (4s，peak) and 350kA rated peak withstand current.
High power test: 550KV/63KA whole pole, 800KV/63KA half pole synthetic test as well as all kinds of tests for 800kV apparatus.
High voltage test: test on AC transmission and distribution equipment with the highest voltage up to 1000kV, and test on DC transmission equipment with the highest voltage up to ±800kV.
