Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another.

The wear-resistant cable PE sheath material can prevent the PE sheath material body from contacting with external objects through the raised structure, increase the wear resistance of the PE sheath material body, strengthen the connection strength of the entire PE sheath material body through the structure of the reinforcing rod, and prevent the PE sheath material body from being damaged by the sun's exposure through the high temperature resistant layer and the heat insulation layer. In addition, the existing sheath material also has the following disadvantages during use:

[0004] (1) Existing sheath materials cannot dissipate heat in high temperature environments, causing the cable temperature to rise, which not only affects the normal use of the cable, but may also accelerate the aging of the cable and reduce its service life;

[0005] (2) The existing sheath material is not provided with an armor layer, making the cable more easily damaged when subjected to such mechanical stress, which may cause the internal conductor of the cable to break or the insulation layer to break. Utility Model Content

[0008] Furthermore, the plurality of wear-resistant metal rods are made of copper, and ends of the plurality of wear-resistant metal rods away from the heat dissipation layer respectively pass through the aluminum alloy armor layer and the wear-resistant sleeve in sequence.

[0009] Furthermore, the adhesive layer is made of thermoplastic, and the flame retardant layer is made of ammonium polyphosphate.

[0011] Furthermore, the heat dissipation layer is made of aluminum, the shape of the heat dissipation layer is cylindrical, and the shielding layer is made of nickel-copper alloy.

[0012] Furthermore, the moisture-proof layer is a protective tube made by mixing raw materials such as cement, asbestos, and quartz sand, the high-temperature resistant layer is made of polyetheretherketone resin material, and the heat insulation layer is made of heat insulation cotton material.

[0013] The advantages of the utility model compared with the existing technology are:

[0014] 1. The utility model provides a wear-resistant cable sheath material.
