AI Technical Summary
In existing low-voltage cables, although the outer sheath is made of environmentally friendly materials, the internal materials are mostly non-environmentally friendly, resulting in a low overall recyclability rate and environmental pollution problems.
The cable is designed using all environmentally friendly materials, including the cable conductor, modified polypropylene insulation reinforcement layer, polypropylene filler rope, and modified polypropylene outer sheath, ensuring that all parts of the cable are recyclable. It uses Class 1 or Class 2 copper conductors to ensure conductivity, and the insulation and sheath layers are made of low-smoke, halogen-free, and low-toxic materials.
This improves the insulation and mechanical properties of the cable, while also enabling the recyclability of all parts of the cable, reducing environmental pollution and costs associated with the disposal of waste cables.

Abstract
Description
Technical Field
[0001] This utility model relates to a recyclable, green, and environmentally friendly low-voltage power cable, belonging to the field of environmentally friendly cable technology. Background Technology
[0002] As one of the world's largest producers and consumers of electrical wires, China leads the world in both market size and growth rate. Recyclable, environmentally friendly, low-smoke, halogen-free materials have broad application prospects. Compared to ordinary cables, they are characterized by high temperature resistance, corrosion resistance, light weight, and impact resistance. The cable conductor, insulation, and sheath materials can all be effectively recycled and reused after reprocessing. This material recycling reduces the cost of disposing of waste cables and environmental pollution. Cables can be used in basic power systems and control systems.
[0003] The application of environmentally friendly new materials has significantly improved the performance of cable products. Although the price of these materials has increased, their superior performance and recyclability, coupled with societal progress and rising environmental requirements, suggest that future market demand for these environmentally friendly cables is likely to further increase. While many existing cables feature environmentally friendly outer sheaths, the internal materials often contain non-environmentally friendly components, resulting in a low overall recyclability rate. Utility Model Content
[0004] The purpose of this invention is to provide a recyclable, green, and environmentally friendly low-voltage power cable that greatly reduces secondary environmental pollution, improves the overall recyclability of the cable, and solves the aforementioned problems in the background technology.
[0005] The technical solution of this utility model is:
[0006] A recyclable, green, and environmentally friendly low-voltage power cable comprises a cable conductor, a modified polypropylene insulation reinforcement layer, a polypropylene filler rope, a polypropylene wrapping tape, and a modified polypropylene outer sheath. The cable conductor is extruded with a modified polypropylene insulation reinforcement layer to form a core. After multiple cores are cabled together, a polypropylene wrapping tape is wrapped around them. The space between the polypropylene wrapping tape and the cores is filled with a polypropylene filler rope. The polypropylene wrapping tape is then extruded with a modified polypropylene outer sheath.
[0007] Furthermore, the cable conductor is made of stranded Class 1 or Class 2 copper conductors.
[0008] The positive effects of this utility model are as follows: the insulation layer and sheath layer of the cable are made of high-performance modified polypropylene material, and the filler of the cable is made of polypropylene filler rope, both of which have the characteristics of low smoke, halogen-free and low toxicity. While increasing the overall insulation protection performance and mechanical performance of the cable, the electrical performance of the cable is also guaranteed. The main metal and non-metal materials of the cable can be recycled and reused. The recycling of materials reduces the cost of waste cable disposal and environmental pollution.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0012] See attached document Figure 1 A recyclable, green, and environmentally friendly low-voltage power cable includes a cable conductor 1, a modified polypropylene insulation reinforcement layer 2, a polypropylene filler rope 3, a polypropylene wrapping tape 4, and a modified polypropylene outer sheath 5. The cable conductor 1 is externally extruded with the modified polypropylene insulation reinforcement layer 2 to form a core. After multiple cores are cabled together, they are externally wrapped with the polypropylene wrapping tape 4. The polypropylene wrapping tape 4 and the core are filled with the polypropylene filler rope 3. The polypropylene wrapping tape 4 is externally extruded with the modified polypropylene outer sheath 5.
[0013] The cable conductor 1 is made of stranded Class 1 or Class 2 copper conductors. The resistance of Class 1 or Class 2 copper conductors meets the GB / T3956 standard, ensuring good conductivity, stable cable structure, improved communication data transmission stability, and extended cable service life.
[0014] The cable conductor 1 is externally extruded with a modified polypropylene insulation reinforcement layer 2 of uniform thickness to form the core. Multiple cores are insulated and cabled together. The cores are filled with polypropylene filler rope 3 to maintain the roundness of the cable after cabling. After cabling, polypropylene wrapping tape 4 is wrapped around the cable with a 20% overlap to maintain the structural stability of the cable cores. The outer sheath is a modified polypropylene outer sheath 5, which has excellent mechanical properties and comprehensive protective performance.
[0015] The insulation layer and sheath of this utility model are made of low-smoke, halogen-free, low-toxic and environmentally friendly materials. The cable conductor 1 is a Class 1 or Class 2 copper conductor. The cable has excellent electrical performance. The copper conductor, insulation layer and sheath layer are all recyclable. The main materials can be reused after processing, which improves the recycling efficiency. It is mostly used in places with high environmental protection requirements.
