摘要(Abstract)：
海底电力电缆施放在海底水域中,因其使用环境的特殊性,海底电缆通常采用粗钢丝铠装保护,从而产生较大的涡流和环流损耗,登陆段的损耗发热成为制约海底电缆输送容量的瓶颈。采用剥去登陆区段电缆的铠装钢丝并单端接地等工艺措施,能有效降低单芯海底电缆登陆段损耗,显著提升输送容量。
Steel armor has been widely used to protect submarine cables,which are laid under the sea,due to the specific characteristics of its operation environment.Therefore,submarine cables suffer great eddy current and circulating current losses.The heat generated in the landing parts of the cables becomes the bottleneck that constrains the transmission capacity.The technological measures such as removing the steel armor of the landing parts and perform single-end grounding can effectively reduce the loss in the landing parts of single-core submarine cables and significantly enhance the transmission capacity.
