摘要:
A radial water barrier is provided for a dynamic high-voltage submarine cable. The water barrier includes a corrugated metal tube having an inner diameter in a range of 50-90 mm and a corrugation pitch in a range of 6-10 mm. The metal tube has a wall thickness in a range of 0.7-1 mm and a corrugation depth of more than 6 mm.
