现有技术中，人们对于海底高压电缆已进行过研究，如：公布号 为CN102290135A、名称为：额定电压220kV三芯光电复合海底电缆，包括从外到内依次分布的外披层、铠装层和内衬层，所述的内衬层内设置有三个两两相外切的电单元，所述的电单元与所述的内衬层所围成的三处空隙处均填充有多个填充单元，三个所述的电单元和所有的填充单元全部绞合形成一股海缆主芯部分，在绞合后的海缆主芯部分外绕包有涂胶布带，所有的填充单元中其中至少一个为光单元，其余的填充单元为填充绳，该种电缆的额定电压达到了220KV。 In the prior art, people have conducted research on submarine high-voltage cables, such as: the publication number is CN102290135A, and the name is: rated voltage 220kV three-core photoelectric composite submarine cable, including the outer drape and armor layer distributed sequentially from the outside to the inside and the lining layer, the inner lining layer is provided with three two-phase circumscribed electrical units, and the three gaps surrounded by the electrical unit and the inner lining layer are filled with a plurality of filling unit, the three electrical units and all the filling units are all stranded to form a main core part of the submarine cable, and the main core part of the stranded submarine cable is wrapped with a rubberized cloth tape. Among all the filling units, at least One is a light unit, and the other filling units are filling ropes. The rated voltage of this kind of cable has reached 220KV.
再如：公布号为 CN101807450A、名称为：一种海底电力电缆，包括由内至外设置的导体(1)、半导电层(2)、绝缘层(3)、缓冲层(4)、铅套(5)、内护套层(6)、铠装层(7)及铠装外保护层(8)，其特征在于：所述内护套层(6)由半导电内护套层与绝缘内护套层两种形式首尾串联而成的混合层，解决了感应电势的问题，及达到降低损耗，提高载流量的目的。 Another example: the publication number is CN101807450A, the name is: a submarine power cable, including a conductor (1), a semiconductive layer (2), an insulating layer (3), a buffer layer (4), and a lead sheath arranged from the inside to the outside (5), inner sheath layer (6), armor layer (7) and armor outer protection layer (8), it is characterized in that: described inner sheath layer (6) is made of semiconductive inner sheath layer and insulation The mixed layer formed by connecting the two forms of the inner sheath layer head to tail solves the problem of induced potential, and achieves the purpose of reducing loss and increasing current carrying capacity.
公布号为 CN101807453A、名称为：用于海底的电力电缆，包括由内至外设置的线芯(1)、屏蔽层(2)、绝缘(3)、绝缘体屏蔽层及内护层(4)、铠装内垫层(5)、铠装层(6)及铠装外保护层(7)，其特征在于：所述线芯(1)是由钢丝导线和铝导线组成，所述钢丝导线位于线芯(1)的中心位置，且钢丝导线与铝导线共同绞合成钢芯铝绞线结构所形成的线芯(1)。它采用的线芯是由钢丝导线和铝导线组成，所述钢丝导线位于线芯的中心位置，且钢丝导线与铝导线共同绞合成钢芯铝绞线结构所形成的线芯。由铝替换了铜，不仅节省了成本，而且导电性也完全符合标准，而其中的钢丝绞铝的混合线，又解决了铝导线抗拉强度不足的问题。 The publication number is CN101807453A, and the name is: power cable for seabed, including wire core (1), shielding layer (2), insulation (3), insulator shielding layer and inner sheath (4) arranged from inside to outside, The armored inner cushion layer (5), the armored layer (6) and the armored outer protective layer (7), are characterized in that: the wire core (1) is composed of a steel wire conductor and an aluminum conductor, and the steel wire conductor is located at The center position of the wire core (1), and the steel wire conductor and the aluminum conductor are twisted together to form the wire core (1) formed by the steel-cored aluminum stranded wire structure.

然而，申请人在经过反复试验后，认为现有技术中的海底用高压电缆还存在结构改进的空间，主要表现在（1）铠装层冗余量过大，主要是抗拉强度方面，现有技术中主要考虑的是电缆的圆整，因此，铠装层采用的加强件远远超出了需求的抗拉强度，造成了资源的浪费；（2）外保护层的耐磨性能、防渗水、防海水性能有待改善；（3）屏蔽层与绝缘层的设置方式可以进一步改进，以更好地改善电缆性能；（4）绝缘层的材料有待进一步研发，使其能达到更高的耐压等级或性能。 However, after repeated tests, the applicant believes that there is still room for structural improvement in the prior art high-voltage cables for submarine use, which is mainly reflected in (1) excessive redundancy of the armor layer, mainly in terms of tensile strength. The main consideration in the existing technology is the roundness of the cable. Therefore, the reinforcement used in the armor layer far exceeds the required tensile strength, resulting in a waste of resources; (2) the wear resistance and anti-seepage of the outer protective layer The performance of water and seawater resistance needs to be improved; (3) The setting method of the shielding layer and the insulating layer can be further improved to better improve the performance of the cable; (4) The material of the insulating layer needs to be further developed so that it can achieve higher resistance pressure rating or performance.
