Product Description
I. Introduction
Aluminum alloy cables are a new type of power transmission cable that has been increasingly widely used in modern electrical engineering. It combines the lightweight characteristics of aluminum and the excellent performance of alloy materials, providing an efficient, reliable, and cost-effective solution for power transmission.
II. Materials and Structure
- Conductor material:
- The conductors of aluminum alloy cables are made of high-quality aluminum alloy. This alloy is formed by adding multiple components such as rare earth, magnesium, copper, and iron to pure aluminum and undergoing a special alloy processing technology. This alloy material not only improves the electrical conductivity of the conductor, enabling its conductivity to approach the level of pure aluminum and reach about 80% of the conductivity of copper core cables, but also greatly enhances the mechanical properties of the conductor, such as tensile strength, creep resistance, and flexibility.
- Compared with pure aluminum conductors, the creep resistance of aluminum alloy conductors is increased by 300%, effectively avoiding the creep relaxation problem caused by thermal expansion and contraction at the connection due to power on and off, reducing the occurrence probability of cable faults.
- Insulation material:
- Cross-linked polyethylene (XLPE) is usually used as the insulation material, which has excellent insulation performance and high-temperature resistance. The operating temperature can reach 90°C, and it can maintain stable insulation performance in a relatively high temperature environment, ensuring the safety and reliability of power transmission.
- XLPE insulation material also has good chemical corrosion resistance and aging resistance, and can resist the erosion of various chemical substances and prolong the service life of the cable.
- Sheath material:
- The external sheath is generally made of polyvinyl chloride (PVC), which has good waterproof, moisture-proof, and corrosion-resistant properties and can protect the internal structure of the cable from the influence of the external environment.
- For some special application scenarios, such as when higher fire resistance or wear resistance is required, other special materials can also be used for the sheath, such as flame-retardant PVC, low-smoke halogen-free polyolefin, etc.
- Armoring structure (optional):
- Some aluminum alloy cables have an armoring structure. The common armoring method is aluminum alloy interlocked armor. This armoring structure can enhance the mechanical strength of the cable and improve the cable's resistance to external forces. Even when subjected to large pressures and impacts, the cable is not easily punctured.
- The armor layer can also play a certain shielding role, reducing the interference of external electromagnetic signals on the internal signals of the cable and improving the signal transmission quality of the cable.
III. Performance Characteristics
- Excellent electrical conductivity: Although the electrical conductivity of aluminum alloy is slightly lower than that of copper, under the same cross-section, the current-carrying capacity of aluminum alloy cables can meet the needs of most power transmission. And in some cost-sensitive projects, aluminum alloy cables have higher cost performance.
- Good mechanical properties:
- High tensile strength: The tensile strength of aluminum alloy conductors is significantly improved compared to pure aluminum conductors, and the elongation is also increased to about 30%, making it able to withstand greater tensile forces without breaking easily, facilitating the laying and installation of cables.
- Good flexibility: Aluminum alloy cables have good bending performance, with a bending radius of only 7 times the cable outer diameter, far better than traditional copper core cables (bending radius of 10 - 20 times the outer diameter), making it convenient for use in narrow spaces or complex wiring environments.
- Low elasticity: Aluminum alloy cables have low elasticity and do not rebound easily after being subjected to external forces, maintaining good shape stability and being beneficial for cable connection and fixation.
- Outstanding corrosion resistance:
- Aluminum itself has certain anti-corrosion properties. When the aluminum surface is in contact with air, a thin and strong oxide layer will form, which can resist various forms of corrosion.
- The addition of chemical elements such as rare earth in the alloy further improves the corrosion resistance of aluminum alloy, especially the electrochemical corrosion resistance, solving the problem of electrochemical corrosion that is prone to occur at the joint of pure aluminum for a long time.
- Moderate coefficient of thermal expansion: The thermal expansion coefficient of aluminum alloy is comparable to that of copper. This makes the expansion and contraction of aluminum alloy cables consistent with that of copper conductors when connected. Avoiding problems such as loose connections or poor contact caused by thermal expansion and contraction.
- Safe and reliable connection performance: The electrical connection made of aluminum alloy is as safe and stable as the connection with copper conductors. When the conductor is annealed, the added iron will produce high-strength creep resistance, ensuring the stability of the connection even under long-term overload and overheating conditions.
- Strong self-weight bearing capacity: Aluminum alloy improves the tensile strength of pure aluminum. Aluminum alloy cables of the same specification are lighter in weight but can support longer spans. For example, aluminum alloy cables can support the self-weight of a length of 4000 meters, while copper cables can only support 2750 meters. This has obvious advantages in wiring of large-span buildings such as stadiums and large factories.
- Environmentally friendly and energy-saving: Aluminum alloy is a renewable resource. Compared with traditional copper, its impact on the natural environment during mining and processing is smaller. And the recycling rate of aluminum alloy cables is relatively high, helping to reduce the dependence on natural resources and environmental pollution.
IV. Application Fields
- Civil buildings: Suitable for power wiring in ordinary residential houses, high-rise buildings, commercial complexes, schools, hospitals and other places. Its lightweight and easy installation characteristics can reduce construction difficulties and costs while meeting the power transmission needs inside buildings.
- Industrial fields: In factories, industrial parks, mines and other industrial places, aluminum alloy cables can provide reliable power supply for various industrial equipment. Its good corrosion resistance and mechanical properties enable it to adapt to harsh industrial environments.
- Transportation facilities: Widely used in the power systems of transportation infrastructure such as railways, subways, airports, and bridges. For example, in sulfur-containing environments such as railway tunnels, the corrosion resistance of aluminum alloy is better than that of copper. Therefore, aluminum alloy cables are an ideal choice.
- New energy fields: In new energy projects such as solar power generation and wind power generation, aluminum alloy cables can be used for power transmission between equipment such as photovoltaic panels and wind turbines and substations. They have good weather resistance and aging resistance and can adapt to the harsh outdoor environmental conditions.
- Municipal engineering: Can be used for power wiring of municipal facilities such as urban road lighting, underground pipe corridors, and municipal squares, providing power guarantee for the normal operation of the city.
V. Production Standards and Certifications
The production of aluminum alloy cables needs to strictly follow relevant international and domestic standards, such as ASTM (American Society for Testing and Materials standards), IEC (International Electrotechnical Commission standards), BSEN (British standards), DIN (German standards), GB/T (Chinese national standards), etc. These standards have made clear regulations and requirements on the material properties, electrical properties, mechanical properties, fire resistance, and flame retardant properties of aluminum alloy cables, ensuring the quality and safety of the cables. At the same time, some high-quality aluminum alloy cable products will also pass certifications by third-party authoritative institutions such as UL (Underwriters Laboratories certification), providing users with more reliable quality assurance.
VI. Installation and Maintenance
- Installation precautions:
- When installing aluminum alloy cables, pay attention to the bending radius of the cable to avoid cable damage due to excessive bending. At the same time, ensure that the cable connection is firm and reliable to avoid problems such as poor contact or loosening.
- For cables with armoring structure, pay attention to protecting the armor layer during the laying process to avoid damage to the armor layer and affect the mechanical strength and shielding performance of the cable.
- Maintenance requirements:
- Regularly inspect and maintain aluminum alloy cables, check whether the cable appearance is damaged or deformed, and whether the cable connection parts are loose or overheated.
- For cables exposed outdoors for a long time, pay attention to checking whether the cable sheath is aged or cracked, and replace the damaged sheath in time to ensure the insulation performance and waterproof performance of the cable.
In conclusion, aluminum alloy cables have become an important product in the field of power transmission with their excellent performance, wide application fields, and good economic benefits. In the future electrical engineering, aluminum alloy cables will continue to play an important role and provide strong support for the development of the power industry.
