Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to an aluminum conductor high voltage shielded cable. Background Art

[0002] Aluminum conductor high-voltage shielded cable is a specially designed high-voltage transmission cable, mainly used for high-voltage power transmission and signal transmission. Unlike ordinary aluminum conductor high-voltage cables, each aluminum conductor in the aluminum conductor high-voltage shielded cable is wrapped with a shielding layer on the outside. The shielding layer is usually made of non-magnetic metals such as aluminum or copper, so that the aluminum conductor high-voltage shielded cable is grounded during use. The specific principle of use is to fully ground the aluminum conductor high-voltage shielded cable when in use, and then conduct the interference signal in the environment to the earth, thereby affecting the conductor inside the aluminum conductor high-voltage shielded cable, and at the same time, it can also reduce its own electromagnetic radiation. Therefore, based on the characteristics of the above-mentioned aluminum conductor high-voltage shielded cable, aluminum conductor high-voltage shielded cable is widely used in high electromagnetic compatibility and high voltage resistance working scenarios.

[0003] In the actual installation process of aluminum conductor high-voltage shielded cable, because aluminum conductor high-voltage shielded cable is used to transmit high-voltage power and signals during the grounding process, the volume of aluminum conductor high-voltage shielded cable itself is relatively large, and it is a cable with a relatively large circumferential area in the cable field. In addition, due to the need to be grounded, an armor layer is also provided inside the aluminum conductor high-voltage shielded cable. Therefore, the aluminum conductor high-voltage shielded cable has a heavier mass and cannot be bent at a large arc. When connecting the connector of the aluminum conductor high-voltage shielded cable to the equipment, the connection between the aluminum conductor high-voltage shielded cable and the equipment often twists, which makes it inconvenient to install the aluminum conductor high-voltage shielded cable.
