Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an armored structure of a high-performance armored cable. Background Art

[0002] Armored cables are primarily used in applications where they can withstand certain mechanical forces. Armored cables are generally available in two basic forms: wire-wound armor and steel-tape armor. The armor layer can also replace a ground wire. Steel-tape armored cables are often used in applications where they can withstand certain positive pressure (compression) but not tension, such as direct burial in soil. Steel-wire armored cables are primarily used in applications where they can withstand both positive pressure and longitudinal tension, such as underwater, in vertical shafts, or in locations with large drop heights. However, their ability to withstand longitudinal tension is still relatively low.

[0003] According to patent number CN201620447174.7, an armored cable is disclosed, which is characterized in that it includes a wrapping tape, three conductive cores and three grounding cores arranged in the wrapping tape, each of the conductive cores is covered with a core insulation layer, and the wrapping tape is filled with a filler; the outside of the wrapping tape is covered with an aluminum alloy armor layer, and the surface of the aluminum alloy armor layer is provided with texture; the outside of the aluminum alloy armor layer is covered with a sheath layer.

[0004] The existing technology has the following problems:

[0005] Existing armored cables have poor protection performance and are difficult to use in harsh environments, resulting in a decrease in the overall performance of the armor layer and the performance of the armored cable. In addition, the current armor structure cannot directly connect cables and requires the use of other components to achieve this connection. Therefore, to address the above problems, an armor structure for high-performance armored cables is proposed. Utility Model Content
