During test, SINDIA, the electric power company and the construction unit exerted their cohesion, overcame difficulties and made their common efforts and successfully completed the final acceptance test for one hour under test voltage 1.7U0 and 493kV by series - parallel connection of 8 German HighVolt WRV83/260T Variable Frequency Resonance System. The maximum test current is up to 292A, and the testing Q value is kept in more than 132 under the condition of continuous work.

SINDIA Attends Urban Power Transmission & Distribution Cable Development Technology Seminar

Recently, SINDIA participated a science and technology project, i.e. “Application of Distributed Partial Discharge Detction on High-voltage Cables with Great Length”, and the project won the first prize of Liaoning Sceientific and Technological Progress Award.

Relying on rich experiences in handover tests of EHV cable and submarine cable and the optimal technical proposals, on 24th November, 2016, SINDIA participated and completed the AC frequency conversion voltage-endurable handover test of the “220kV photoelectric composite submarine cables of Jiangsu Dongtai 200MW Offshore Wind Power Project”, where the test voltage was up to 216kV (1.7U0) and the test current was 154A.
