[0002] Copper stranded wire refers to a new type of composite conductor made of low-carbon steel as the core, copper-plated, and twisted into several single wires according to a certain rule. Copper stranded wire is a soft connecting wire for power transmission and distribution, electrical equipment (such as transformers, electric furnaces), electronic and electrical equipment, and thyristor components. In addition, copper stranded wire can also be used as grounding wire for electrical work. Copper stranded wire is achieved by twisting single wires around the stranded wire axis at equal angular velocity and the stranded wire moving forward at a uniform speed.

[0021] Please refer to Figure 1-4 A high-strength copper stranded wire includes a core 1, a copper wire 2 is wrapped on the outside of the core 1, and the outer surface of the copper wire 2 is wrapped with a first sheath 3, and the outer surface of the first sheath 3 is wrapped with a second sheath 4, the outer surface of the second sheath 4 is wrapped with an insulating layer 5, and the outer side of the insulating layer 5 is wrapped with a fireproof layer 6, and the outer surface of the fireproof layer 6 is wrapped with a reinforced shell 7.

[0022] The core 1 is made of glass fiber, which has high tensile strength, so that the core 1 can withstand large tensile forces. Glass fiber is a relatively lightweight material, which makes the core 1 light as a whole. Glass fiber has good corrosion resistance to water, chemicals and most corrosive substances, which enables the core 1 to operate stably for a long time in harsh environments and extend its service life. Glass fiber is an insulating material and is non-conductive. The core 1 can provide good electrical insulation performance in electrical equipment and reduce the risk of failure of electrical equipment. Glass fiber has high high temperature resistance, which enables the core 1 to work in a high temperature environment without losing its structural strength and performance, which is very important for applications that need to operate under high temperature conditions. The thermal expansion coefficient of glass fiber is relatively low, which enables the core 1 to maintain a relatively stable size when the temperature changes, which helps to reduce the stress caused by thermal expansion and increase the stability of the core 1.

[0023] The copper wire 2 is composed of three groups of wires twisted together, and the side of the three groups of wires close to each other is tightly attached to the outer surface of the core 1. By twisting the three groups of wires together and placing them close to the outer surface of the core 1, the strength of the overall structure can be increased, which helps to improve the carrying capacity of the copper wire 2, making it more suitable for applications that need to withstand greater tension or stress environments. The design of twisted wires increases the flexibility of the copper wire 2, making it easier to bend and adapt to different installation environments. The twisted wires can reduce the generation of electromagnetic interference. The tight fit on the side close to the core 1 can reduce the gap between the wires, reduce electromagnetic wave radiation, and help improve the anti-interference performance of the line. The tight twisting of the wires and the design of close contact with the core 1 can also help reduce the interference of external substances on the line, such as moisture, chemicals, etc., which improves the stability and reliability of the line. The twisted structure of the wires can increase the surface area of ​​the wire and help dissipate heat. Under high load or high current transmission conditions, it helps to keep the line temperature within a controllable range and improve the safety and reliability of the wire.

[0024] The first sheath 3 is composed of a braided structure. The braided structure sheath can effectively enhance the wear resistance of the wire. It can provide an additional protective layer, reduce the friction and wear between the wire and the external environment, and extend the service life of the wire. The braided structure sheath is usually softer than other types of sheaths and is easier to bend and fold, making the wire more flexible and easy to handle during installation and wiring. The braided structure can provide additional anti-tensile support, so that the wire is better able to withstand pulling and tension, which is especially important for wires that need to be used in applications with greater pulling force. The braided structure sheath can provide a certain degree of electromagnetic shielding effect and reduce the impact of electromagnetic interference. It is very useful for protecting the wire from external electromagnetic interference and reducing the interference of the wire to surrounding electronic equipment. The braided structure sheath can effectively prevent the wire from physical damage and can protect the wire from damage by the external environment.

[0025] The second sheath 4 is made of metal material, and the metal material is steel mesh material. The steel mesh material usually has high mechanical strength and rigidity, and can effectively protect the wire from external physical impact and extrusion. This strength enables the second sheath 4 to remain stable under harsh environmental conditions and provide reliable protection. The steel mesh is usually galvanized or otherwise treated with anti-corrosion and has good corrosion resistance. The second sheath 4 can resist corrosion caused by most chemicals and harsh environments, extending the service life of the wire. The metal material has good electromagnetic shielding performance and can effectively block external electromagnetic interference, which is very important for protecting the wire from electromagnetic interference and ensuring signal transmission. The stability and reliability of transmission are very important. The wire mesh material usually has good fire resistance and can effectively prevent the spread of fire, which enables the second sheath 4 to provide additional protection when a fire occurs and reduce the damage to the line and equipment caused by the fire. The second sheath 4 made of metal can effectively resist damage to the line by external objects, such as cutting, abrasion or impact, which improves the safety and reliability of the line in harsh environments and high-risk areas. The wire mesh material has a long service life and stability and is not easily affected by external factors, which enables the second sheath 4 to maintain its protective performance and mechanical strength for a long time, reduce the frequency of maintenance and replacement, and reduce the overall cost.

[0026] The insulating layer 5 is made of polyvinyl chloride (PVC). PVC has good electrical insulation properties, can effectively prevent current from passing through, reduce the risk of leakage of the line, and protect the safety of equipment and personnel. PVC has good heat resistance within a certain temperature range and can maintain stable performance under certain temperature conditions. It is suitable for some medium and low temperature applications. PVC has good corrosion resistance to most chemicals and can resist the erosion of chemicals such as acids, alkalis, oils and fats, thereby extending the service life of the line. PVC has good processability and is easy to form, cut and connect, making it easy to manufacture insulating layers 5 of various shapes and sizes to meet the needs of different line designs. PVC has certain wear resistance and tensile resistance, can effectively protect the wire core 1 and the conductor, and reduce the damage to the line by the external environment. PVC is a relatively cheap material with low manufacturing cost. It is suitable for large-scale production and helps to reduce the cost of line manufacturing. PVC material is recyclable, and the waste generated during the manufacturing process can be recycled or safely disposed of, which is beneficial to environmental protection.

[0027] The fireproof layer 6 is made of high-temperature resistant silicone material, and rubber spherical bumps are evenly distributed on the outer surface of the reinforced shell 7. Silicone is a high-temperature resistant material that can maintain stable performance under high temperature environment, which enables the fireproof layer 6 to effectively protect the safety of the line in the event of a fire. The distribution of the rubber spherical bumps helps the fireproof layer 6 to form a certain isolation layer when a fire occurs, slowing down the spread of fire and improving the damage resistance of the line in a fire. The rubber spherical bumps are evenly distributed on the outer surface to form a protective layer that can prevent the invasion of external objects, dust, etc., thereby keeping the line clean and operating normally. The distribution of rubber spherical bumps on the surface of the shell can improve the mechanical compressive resistance of the shell, slow down the physical impact of the outside world on the line, and improve the durability of the line. The design of the spherical bumps helps to increase the friction of the shell surface, improve the anti-slip property of the fireproof layer 6 during installation and maintenance, and reduce the occurrence of accidents.
