They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater power transmission across rivers and seas. Power cables are usually insulated with an insulation layer, which is extruded plastic. Commonly used plastics include polyvinyl chloride, polyethylene, and cross-linked polyethylene, such as Figure 1 The cable structure in Figure 1 The cable structure has a protective layer, but it is easily squeezed by external objects during use. Due to insufficient support strength inside the cable, the cable inside the cable is damaged.

[0010] Furthermore, the cross-section of the support tube is diamond-shaped, and each outer surface of each support tube is connected to a support tube and constitutes the support part; the support part formed by the outer surfaces of multiple support tubes can support the space between the support body and the cable. When the cable is squeezed or impacted from the outside, not only can the support body be used to offset part of the external force, but the honeycomb-shaped support part can also be used to offset part of the external force again, and effectively support and protect the cable, which can avoid the internal cable of the cable from being damaged due to external force during use, and can further improve the overall service life of the cable.

[0011] Furthermore, the first support assembly includes at least three support bodies, the three support bodies are connected in a triangle shape, and the outer surfaces of the three support bodies are connected at the connection points; and the cross-section of each support body is elliptical.

[0012] Furthermore, reinforcing ribs are respectively provided on the connecting surfaces of the three supporting bodies; the supporting bodies are further supported by the reinforcing ribs, and the stability of the triangle is utilized to prevent the internal cables of the cable from being damaged due to external forces during use, thereby further improving the overall service life of the cable.

[0013] Furthermore, the second support assembly includes a support cylinder and a support member;

[0014] The support cylinder is covered on the outside of the first support assembly;

[0015] One end of the support member is connected to the support cylinder, and the other end of the support member is connected to the inner wall of the shell;

[0016] The support member, the shell and the support cylinder form a buffer space, so that when the cable shell is subjected to external force, the buffer space can buffer and offset the external force, thereby preventing the cable inside the cable from being damaged due to external force during use.
