Dagangshan 500000 volt power cable voltage test completed successfully

On June 17, Dagangshan Hydropower Station 4 units of 500 kV cable voltage withstand test is completed. Test result is consistent with the requirements of regulation, a number of owners, design, supervision, and other units of the witnessed the hydropower seven innings this major node of the target.

4 units in Dagangshan Hydropower Station of a 500 kV cable 12 root, the shortest 908 metres, the 953 meters long, AC voltage on-site compression program carried out for a total of three stages I, II, III, and the maximum test voltage 510 kV. Pressure test from June 7th began, which lasted 11 days.

Project overcomes the difficulties of high voltage cable laying path range, high-voltage test the safety door area wide, but gate operation etc., elaborate organization, and ultimately ensure the successful completion of the 500 kV cable voltage withstand test.
