[0009] Preferably, the control cable includes a control cable conductor, which is a second copper conductor, an outer insulation layer, which is a second polyester tape, and an outer insulation layer, which is a second synthetic mica tape.

[0010] Furthermore, the insulation layer of the composite cable is made of polyvinyl chloride or cross-linked polyethylene.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] like Figures 1 to 4 As shown, a composite cable of this utility model includes:

[0024] The composite cable outer sheath 1 includes a composite cable insulation layer 4, a composite cable reinforcing layer 5 wrapped around the composite cable insulation layer 4, and a composite cable outer sheath 6 wrapped around the composite cable reinforcing layer 5. Multiple sets of power cables 2 are installed inside the composite cable insulation layer 4, and control cables 3 are installed at positions adjacent to the composite cable insulation layer 4 between two sets of adjacent power cables 2. Integrating the power cables 2 and control cables 3 into the same composite cable outer sheath 1 can effectively reduce the space required for cable laying and simplify the wiring system. By adding a composite cable reinforcing layer 5 outside the composite cable insulation layer 4, the overall mechanical strength and durability of the cable are improved, enabling it to adapt to more complex working environments. The composite cable insulation layer 4 can provide better electrical isolation performance, reducing the risk of electrical accidents such as short circuits. The placement of control cables 3 at positions adjacent to the composite cable insulation layer 4 between two sets of adjacent power cables 2 allows for better organization of cable layout and avoids signal interference. The composite cable outer sheath 6 provides additional protection for the cable, enabling it to withstand harsh environmental conditions such as water and chemical corrosion. It has a high wiring space utilization rate and strong adaptability.

[0025] like Figures 1 to 4 As shown, as a preferred embodiment, the power cable 2 includes a power cable conductor 8, which is a first copper conductor. The power cable conductor 8 is wrapped with a power cable conductor isolation layer 9, which is a first polyester tape. The power cable conductor isolation layer 9 is then wrapped with a power cable insulation layer 10, which is a first synthetic mica tape. Using a first copper conductor as the power cable conductor 8 significantly reduces resistance loss during power transmission and improves power transmission efficiency. The first polyester tape power cable conductor isolation layer 9 wrapping the power cable conductor 8 provides good electrical isolation, further enhancing the cable's insulation performance. The power cable insulation layer 10, made of first synthetic mica tape, has excellent high-temperature resistance and long-term stability, ensuring stable operation of the cable for extended periods in high-temperature environments. The selection of these materials not only improves the cable's electrical performance but also significantly increases its service life. The combined use of the power cable conductor isolation layer 9 and the power cable insulation layer 10 effectively prevents short-circuit accidents in the power cable 2, improving the safety of the entire cable system.

[0026] like Figures 1 to 4As shown, as a preferred embodiment, the control cable 3 includes a control cable conductor 11, which is a second copper conductor. The control cable conductor 11 is wrapped with a control cable conductor isolation layer 12, which is a second polyester tape. The control cable conductor isolation layer 12 is then wrapped with a control cable insulation layer 13, which is a second synthetic mica tape. Using a second copper conductor as the control cable conductor 11 significantly reduces resistance loss during signal transmission, improving signal clarity and stability. The second polyester tape control cable conductor isolation layer 12 provides good electrical isolation, further enhancing the cable's insulation performance and effectively preventing signal interference. The control cable insulation layer 13, made of second synthetic mica tape, has excellent high-temperature resistance and long-term stability, ensuring stable operation of the cable for extended periods in high-temperature environments. The selection of these materials not only improves the cable's electrical performance but also significantly increases its service life. The combined use of the control cable conductor isolation layer 12 and the control cable insulation layer 13 effectively prevents short-circuit accidents in the control cable 3, enhancing the safety of the entire cable system.

[0027] like Figures 1 to 4 As shown, as a preferred embodiment, the composite cable insulation layer 4 is made of polyvinyl chloride or cross-linked polyethylene. Both materials have excellent insulation properties, which can effectively reduce the electric field strength inside the cable, reduce leakage, and improve the electrical performance of the cable. Both polyvinyl chloride and cross-linked polyethylene materials have good heat resistance and chemical corrosion resistance, which can ensure the stable operation of the cable in high temperature or chemical corrosion environments and extend the service life of the cable.

[0028] like Figures 1 to 4 As shown, as a preferred embodiment, the composite cable reinforcing layer 5 includes at least one layer of fiber reinforcing material, which is selected from carbon fiber, glass fiber or aramid fiber; these materials have extremely high tensile strength and compressive strength, which can significantly improve the overall mechanical strength of the cable.

[0029] like Figures 1 to 4 As shown, as a preferred embodiment, the outer sheath 6 of the composite cable is made of abrasion-resistant and weather-resistant materials, namely thermoplastic elastomers or polyurethane. Thermoplastic elastomers or polyurethanes have excellent abrasion resistance, which can significantly improve the cable's abrasion resistance and extend its service life. Thermoplastic elastomers or polyurethanes have good weather resistance, which can resist the erosion of ultraviolet rays, ozone and other atmospheric factors, ensuring the long-term stable operation of the cable in the outdoor environment.

[0030] like Figures 1 to 4As shown, as a preferred embodiment, a shielding layer is provided between the outer sheath 6 of the composite cable and the reinforcing layer 5 of the composite cable. The shielding layer is composed of metal braided wire or metal foil. The shielding layer can effectively block external electromagnetic interference, improve the electromagnetic compatibility of the cable, and ensure that the power cable 2 and the control cable 3 work normally in complex electromagnetic environments.

[0031] like Figures 1 to 4 As shown, as a preferred embodiment, multiple sets of power cables 2 are provided with reinforcing ribs 7 in the middle; the setting of reinforcing ribs 7 can significantly improve the mechanical strength of power cables 2, especially in the middle of the cable, and enhance the overall structural stability of the cable.
