其中，所述控制线芯包括铜丝绞合成铜导体和在所述铜导体导线线芯上的绕包两层陶瓷化硅橡胶带。
其中，所述高强度抗拉填充层为聚氯乙烯。
本发明的工作原理为：导体为镀锡5类铜导体；中间两根动力线芯及扇形填充中间的控制绝缘线芯绝缘材料为交联聚乙烯绝缘，区别在于控制线芯的导体和绝缘层之间重叠绕包两层陶瓷化硅橡胶带；动力线芯成缆后（填充高强度抗拉棉绳）再编织碳纤维屏蔽，编织密度不小于90%；外侧再填充四根扇形（内含控制线芯）发泡聚乙烯填充条，再编织一层凯夫拉纤维编织加强层；然后再挤包一层中密度聚乙烯内护；再挤包一层发泡聚乙烯护套；整体外护套采用中密度聚乙烯外护套。利用阿基米德定律—液体中的物体受到向上的浮力，其浮力大小等于物体所排开的液体重量这一原理，实现电缆漂浮的目标。
有益效果：本发明与传统技术相比，存在以下优点：
（1）本发明采用铜导体，具有优异的机械性能及导电性能；
（2）本发明采用扇形发泡聚乙烯及控制线芯组合结构，在增加电缆体积的情况下实现动力传输、信号控制合二为一的目的；

（5）本发明采用高强度抗拉棉绳及凯夫拉纤维编织加强层，质量轻，保证电缆抗拉及抗风性能；
（6）本发明采用中密度聚乙烯内、外护套保证电缆的径向防水性能；
（7）本发明在中密度聚乙烯护套中间挤包发泡聚乙烯（发泡度90%）护套，增加电缆体积及结构稳定性；
（8）本发明采用的扇形发泡聚乙烯填充条外侧再编织一层凯夫拉纤维编织加强层，增强线缆整体抗拉性能；
（9）本发采用凯夫拉纤维编织加强层外侧挤包一层中密度聚乙烯护套，起到径向防水的功能；
（10）本发明采用中密度聚乙烯内护外侧再挤包一层发泡聚乙烯护套，再次增加电缆体积，达到电缆漂浮的目的。
