SUBMARINE POWER CABLES - Veri Cable The types of submarine cables can be divided into three-core submarine cables and single-core submarine cables by structure. Most of the low- and medium-voltage lines use three-core submarine cables, and most of the high-voltage lines use single-core submarine cables. The load type is divided into HVDC submarine cable and HVAC submarine cable. HVAC submarine cable is characterized by large losses, but the operation and maintenance technology is mature, supporting small construction costs. HVDC submarine cable is characterized by small losses, and easy to achieve long-distance transmission of electricity. DC cable in the transmission capacity, loss, length, and stability performance is better than the AC cable. But the DC cable supporting the construction costs are high. Therefore, designers of submarine cable lines usually have to make technical and economic trade-offs to choose the right type of cable. To achieve maximum benefits.
