Using High-Voltage Direct-Current  cables (HVDC) and converters and inverters at either end to make the power usable, electrical losses over the entire length of  the Sun Cable will only add up to around 10%.

在两端使用高压直流电缆 (HVDC) 以及转换器和逆变器来提供电力，Sun 电缆整个长度上的电力损耗加起来只会达到 10% 左右。

As it stands today the deepest HVDC cable  sits at a depth of 1,600 metres between Italy and Sardinia,but Italian cable manufacturer Prysmian is developing technology that  can lay cables as deep as 3,000 metres.

就目前而言，最深的 HVDC 电缆位于意大利和撒丁岛之间 1,600 米的深度，但意大利电缆制造商 Prysmian 正在开发可以铺设深达 3,000 米的电缆的技术。
