[0020] Specifically, the aluminum alloy conductor 11 adopts a high-strength heat-resistant aluminum alloy water-resistant conductor, and the cross-section range of the three-core conductor is 2.5-630 mm 3 .

[0021] Specifically, the thermoplastic polypropylene insulation layer 12 is made of polypropylene insulation material, and polypropylene is an excellent electrical insulation material, and the cable has high resistivity, which can effectively prevent current leakage and ensure the safety of power transmission. In the process of alternating current transmission, the dielectric loss of the polypropylene cable is low, which helps to reduce energy loss and improve power transmission efficiency. Polypropylene insulation has good resistance to most chemicals, and can maintain stable performance even in humid or corrosive environments, which makes polypropylene insulated cables suitable for outdoor or harsh industrial environments. Polypropylene cable is compatible with metal conductors such as copper and aluminum, and will not cause corrosion to the metal. This helps to improve the overall performance and service life of the cable. Polypropylene is also a recyclable material that does not pollute the environment. The use of polypropylene insulated cables helps to achieve sustainable development and environmental protection.
