英国电网拟建一条创纪录的直流输电海底电缆 ,从英国的哈特尔浦到挪威的斯塔万格 ,全长 70 0ｋｍ。该电缆铺设在水深 5 0 0ｍ下。这项工程已作了技术评估 ,证明是可行的。输电最大容量为 130 0ＭＷ。使英国能进口挪威的峰荷水电 ,也可向挪威出口非峰荷电力 ,以帮助挪威维持水库 British grid plans to build a record-breaking HVDC submarine cable, from Hartlepool in Britain to Stavanger in Norway, for a total length of 70 km. The cable is laid at a water depth of 500m. The project has been technically evaluated to prove that it is feasible. Transmission maximum capacity of 130 0MW. So that the United Kingdom can import Norway’s peak electricity and water, Norway can also export non-peak load power to help Norway to maintain the reservoir
