本实用新型是针对上述现有技术中存在的电缆强度低、自身重量大、抗恶劣环境差等不足，而提供的一种高强度电缆。 The utility model provides a high-strength cable aiming at the disadvantages of the prior art, such as low cable strength, heavy weight, and poor resistance to harsh environments.
为了解决上述技术问题，本实用新型采用如下技术方案： In order to solve the above technical problems, the utility model adopts the following technical solutions:
一种高强度电缆，包括电缆芯、绝缘层、屏蔽层及外护套，其特征在于，还包括混合铠装层，所述的混合铠装层由碳纤维丝与钢丝在电缆横截面上间隔排列成环状结构。 A high-strength cable, including a cable core, an insulating layer, a shielding layer, and an outer sheath, is characterized in that it also includes a mixed armor layer, and the mixed armor layer is arranged at intervals on the cable cross section by carbon fiber wires and steel wires into a ring structure.
本实用新型的有益效果：本实用新型采用混合铠装层，且混合铠装层由碳纤维丝与钢丝间隔排列构成环状结构的设计，其中由于碳纤维的比重不到钢的四分之一，抗拉强度为3500Mp以上，是钢的7-9倍，因此可以大大提高铠装层的抗拉强度并有效降低电缆本身的重量，从而可更好的应用于大长度，大截面，大跨度的输电系统中；另外，此种混合铠装层与一般镀锌圆钢丝铠装层相比，可有效减少铠装涡流的损耗。 Beneficial effects of the utility model: the utility model adopts a hybrid armor layer, and the hybrid armor layer is designed with carbon fiber wires and steel wires arranged at intervals to form a ring structure. The tensile strength is more than 3500Mp, which is 7-9 times that of steel, so the tensile strength of the armor layer can be greatly improved and the weight of the cable itself can be effectively reduced, so that it can be better applied to large-length, large-section, and large-span power transmission In addition, this kind of mixed armor layer can effectively reduce the loss of armored eddy current compared with the general galvanized round steel wire armor layer.
进一步，在所述的混合铠装层外包覆有钢带。所述的外层采用钢带反扎，可提高电缆的使用寿命。 Further, the hybrid armor layer is coated with a steel strip. The outer layer is anti-tied with steel tape, which can increase the service life of the cable.
