[0021] Refer toFigures 1 - 3 The utility model provides an embodiment: a communication power composite cable, comprising a cable body 1, a battery core layer 13 is arranged inside the cable body 1, a shielding layer 12 is arranged outside the battery core layer 13, an isolation layer 11 is arranged outside the shielding layer 12, a filling layer 10 is arranged outside the isolation layer 11, a waterproof and breathable layer 9 is arranged outside the filling layer 10, a reinforcement layer 8 is arranged outside the waterproof and breathable layer 9, a low-smoke and halogen-free layer 7 is arranged outside the reinforcement layer 8, a fireproof layer 6 is arranged outside the low-smoke and halogen-free layer 7, a heat-stabilizing layer 5 is arranged outside the fireproof layer 6, an anti-aging layer 4 is arranged outside the heat-stabilizing layer 5, a wear-resistant layer 3 is arranged outside the anti-aging layer 4, and an anti-corrosion layer 2 is arranged outside the wear-resistant layer 3.

[0022] A battery core layer 13 is arranged inside the cable body 1, which is the core part of the cable and is responsible for transmitting electricity or signals to ensure stable transmission of electricity and signals. A shielding layer 12 is arranged adjacent to the outside of the battery core layer 13, and its function is to reduce the influence of external electromagnetic interference on the signal and prevent the electromagnetic radiation inside the cable from interfering with the outside world. The outside of the shielding layer 12 is an isolation layer 11, which provides electrical isolation between the battery core layers 13 to prevent mutual interference between different battery cores, and also protects the battery cores from the influence of the external environment. The outside of the isolation layer 11 is a filling layer 10, which is used to support the internal structure of the cable, maintain the overall stability of the shape and structure of the cable, and provide a buffering effect when the cable is bent. The outside of the filling layer 10 is a waterproof and breathable layer 9, which can effectively prevent the intrusion of water and moisture, and allow the internal water vapor to escape, keep the inside of the cable dry, and avoid damage caused by moisture. The outside of the waterproof and breathable layer 9 is a reinforcing layer 8, which increases the mechanical strength and tensile strength of the cable, so that the cable can be used in construction. The outer part of the reinforcement layer 8 is the low-smoke halogen-free layer 7, which will not produce toxic smoke when burning, thereby improving the safety of the cable in a fire environment and reducing the smoke density when a fire occurs. The outer part of the low-smoke halogen-free layer 7 is the fireproof layer 6, which can prevent or slow down the spread of flames when a fire occurs, and protect the cable and the surrounding environment. The outer part of the fireproof layer 6 is the heat-stable layer 5, which can keep the cable performance unchanged in a high temperature environment and prevent the occurrence of thermal aging. The outer part of the heat-stable layer 5 is the anti-aging layer 4, which can resist the long-term erosion of the cable by environmental factors and extend the service life of the cable. The outer part of the anti-aging layer 4 is the wear-resistant layer 3, which provides physical protection for the surface of the cable to prevent the cable from being damaged by friction or other physical factors in daily use. The outermost anti-corrosion layer 2 is made of corrosion-resistant material, which provides the cable with the last line of defense against chemical corrosion and environmental factors, ensuring that the cable can maintain good performance in various harsh environments.

[0023] Reference Figure 2 and Figure 3, the material of the anti-corrosion layer 2 is asphalt epoxy anti-corrosion coating, the material of the wear-resistant layer 3 is polyurea, the material of the anti-aging layer 4 is nitrile rubber, the material of the fire-proof layer 6 is polyvinyl chloride, the material of the thermal stability layer 5 is cross-linked polyethylene, the thickness of the thermal stability layer 5 is about 1-3 mm, the material of the low-smoke and halogen-free layer 7 is halogen-free flame-retardant polyethylene, the thickness of the low-smoke and halogen-free layer 7 is about 1-2 mm, the material of the strengthening layer 8 is glass fiber, the waterproof and breathable layer 9 is composed of a composite of PTFE film and non-woven fabric, the material of the filling layer 10 is foamed polyethylene, the thickness of the filling layer 10 is about 1-3 mm, the material of the isolation layer 11 is polyester film, and the material of the shielding layer 12 is metal foil.

[0024] The material of the anti-corrosion layer 2 is asphalt epoxy anti-corrosion coating. Asphalt epoxy can form a dense protective film, effectively preventing moisture, salts and other chemical substances from eroding the cable, thus ensuring the stable operation of the cable in harsh environments. The material of the wear-resistant layer 3 is polyurea. Polyurea is a high-performance elastomer material. Polyurea materials can resist mechanical wear and cutting, protecting the cable from damage during laying and operation. The material of the anti-aging layer 4 is nitrile rubber. Nitrile rubber is a synthetic rubber with good oil resistance and anti-aging performance. It can effectively resist the influence of environmental factors such as ultraviolet rays, ozone and high temperatures, thereby extending the service life of the cable. The material of the fire-proof layer 6 is polyvinyl chloride (PVC). PVC is a commonly used flame-retardant material. It can inhibit the spread of fire when the cable has a short circuit or catches fire, reducing the combustion risk of the cable. The material of the thermal stability layer 5 is cross-linked polyethylene, which has good thermal stability and mechanical strength. The thickness of the thermal stability layer 5 is about 1 - 3 mm, which is sufficient to withstand the heat generated during the operation of the cable and prevent the occurrence of thermal aging. The material of the low-smoke and halogen-free layer 7 is halogen-free flame-retardant polyethylene. This material not only has excellent flame-retardant performance, but also does not produce toxic halogen gases and a large amount of smoke when burning, improving the safety and evacuation efficiency during a fire. The thickness of the low-smoke and halogen-free layer 7 is about 1 - 2 mm, ensuring the fire safety of the cable. The material of the strengthening layer 8 is glass fiber, which can improve the tensile strength and compressive performance of the cable. The waterproof and breathable layer 9 is composed of a composite of PTFE (polytetrafluoroethylene) film and non-woven fabric. The PTFE film has excellent waterproofness and breathability, which can prevent moisture from entering the cable interior, while allowing internal moisture to escape, keeping the cable interior dry. The material of the filling layer 10 is foamed polyethylene, which can fill the voids inside the cable, making the cable structure more compact and also improving the mechanical protection performance of the cable. The thickness of the filling layer 10 is about 1 - 3 mm. The material of the isolation layer 11 is polyester film. Polyester film has good electrical insulation performance and mechanical strength. It can effectively isolate the core layer 13, preventing mutual interference between the cores. The material of the shielding layer 12 is metal foil. Metal foil can provide good electromagnetic shielding effect, reducing the influence of external electromagnetic interference on signal transmission, and at the same time can also prevent the electromagnetic radiation inside the cable from interfering with the outside world.

[0025] Working principle: The core layer 13 undertakes the main task of transmitting electricity or signals. Surrounding the core layer 13 is the shielding layer 12, which can effectively reduce the influence of external electromagnetic interference on signal transmission and ensure signal integrity. Adjacent to the shielding layer 12 is the isolation layer 11, which can provide necessary electrical isolation to prevent signal interference between different cores. Outside the isolation layer 11 is the filling layer 10, which is used to support the internal structure, maintain the shape of the cable and the overall stability of the structure. Outside the filling layer 10 is the waterproof and breathable layer 9, which has a special microporous structure that can prevent moisture intrusion while allowing air to pass through to balance the internal pressure. The strengthening layer 8 is located outside the waterproof and breathable layer 9 and is made of high-strength materials, increasing the mechanical strength and tensile resistance of the cable. Outside the strengthening layer 8 is the low-smoke and halogen-free layer 7, which can provide low-smoke and low-toxicity fire protection. The fireproof layer 6 follows the low-smoke and halogen-free layer 7 and contains a flame retardant that can slow down the spread of fire in case of a fire. The thermal stability layer 5 is located outside the fireproof layer 6 and is made of materials with good thermal stability to ensure that the cable will not be damaged due to thermal aging in a high-temperature environment. The anti-aging layer 4 covers the thermal stability layer 5 and contains anti-ultraviolet and antioxidant agents to effectively extend the service life of the cable. The wear-resistant layer 3, as a protective layer, is located outside the anti-aging layer 4 to provide additional physical protection to prevent the cable from being worn during daily use. The outermost anti-corrosion layer 2 is composed of corrosion-resistant materials, providing the last line of defense against chemical corrosion and environmental factors for the cable, effectively improving the performance of the communication and power composite cable, ensuring the stability and safety of signal transmission, and extending the service life.
