ã€China Aluminum Industry Network】 The popularization and application of new materials and new products for aluminum alloy cables will be overwhelming. This is the need to build a resource-saving society, the need to save construction costs in the market, and the need for technological progress. From the recent development trend of the market, some large cable demanders have turned their demand to choose aluminum alloy cables. The popularity of aluminum alloy cable technology and products in the country, the technology, product quality and comprehensive ability of various production companies in the industry have been basically clear, and the brand level has a clear guidance. Which technologies, such as high-end users who have comprehensive capabilities, are willing to accept new things, and who also pay attention to costs, have begun to pay close attention to high-quality aluminum alloy cable brands. The common characteristic of the high-end users in the industry is the pursuit of quality, the pursuit of perfect connection applications, and fully affirms and recognizes the necessity of the maturity and application of the aluminum alloy terminal connection solutions with matching aluminum alloy cable matching and cable performance. The market entering the stage of rational development is fair. From the current market trend, it can be seen that those high-end users who truly recognize the value and advantages of aluminum alloy cables basically have a full set of technical product solutions and truly professional high-end brands. Although the mid-end users have weak technical capabilities and have a sense of quality pursuit, they do not fully understand the real application conditions of aluminum alloy cables, and are easily misled by so-called professional companies. They are often hesitant to choose their brands and are difficult to choose and use. Aluminum alloy cable products. Low-end users basically have no real technical ability and poor quality awareness. Brand selection only pays attention to low prices, so that falling into the trap of counterfeit products not only harms others, but also contributes to the proliferation of counterfeit products in the market. 1. Conductive properties: The electrical conductivity of aluminum alloy is 61.5% that of the commonly used reference material copper IACS, and the current carrying capacity is 79% of copper, which is superior to the pure aluminum standard. 2. Creep resistance performance: The alloy material and annealing process of aluminum alloy conductors reduce the tendency of conductors to "creep" under heat and pressure. Compared to pure aluminum, the creep resistance is improved by 300%, and cold flow is avoided. Or creep caused relaxation problems. 3, tensile strength and elongation: aluminum alloy conductor compared to pure aluminum conductor, due to the addition of special components and the use of a special processing technology, greatly improving the tensile strength, and the elongation rate increased to 30%, Use more safe and reliable. 4. Thermal expansion coefficient: The thermal expansion coefficient is used to calculate the dimensional change of the material when the temperature changes. Aluminum alloys have a coefficient of thermal expansion comparable to that of copper, and aluminum connectors have been reliably used for copper and aluminum conductors for many years, and most of the electrical connectors used today are made of aluminum, which is particularly suitable for aluminum alloys. Therefore, the expansion and contraction of the aluminum alloy conductor and the connector are completely the same. 5, strong weight bearing capacity Aluminum alloy to improve the tensile strength of pure aluminum, aluminum alloy cable can support 4000 meters in length of self weight, copper cable can only support 2750 meters. This advantage is particularly prominent in the wiring of large-span buildings (such as stadiums). 6. Corrosion Resistance The inherent corrosion resistance of aluminum stems from the fact that when the aluminum surface comes into contact with air, a thin and strong oxide layer is formed. This oxide layer is particularly resistant to various forms of corrosion. The addition of rare earth elements in the alloy can further improve the corrosion resistance of the aluminum alloy, especially electrochemical corrosion. Aluminum's ability to withstand harsh environments has made it widely used in cable tray conductors, as well as many industrial components and containers. Corrosion is usually related to the connection of different metals in a wet environment. Corresponding protective measures can be used to prevent corrosion, such as the use of lubricating oils, antioxidants, and protective coatings. Alkaline soils and some types of acidic soils are more corrosive to aluminum. Therefore, aluminum conductors laid directly on the ground should be protected against corrosion by using insulating layers or molded sheaths. In sulfur-containing environments such as railway tunnels and other similar places, aluminum alloys have much better corrosion resistance than copper. 7, flexible aluminum alloy has a good bending performance, its unique alloy formula, processing technology, a substantial increase in flexibility. Aluminum alloy is 30% more flexible than copper and 40% lower in resilience than copper. Generally, the bending radius of the copper cable is 10 to 20 times the outer diameter, while the bending radius of the aluminum alloy cable is only 7 times the outer diameter, and the terminal connection is easier. 8, armored characteristics of domestic commonly used armored cable, mostly steel tape armor, low security level, when subjected to external destructive power, its poor resistance, easily lead to breakdown, and heavy weight, installation costs are very high, plus Poor corrosion resistance, long service life. The metal chained armored cable developed by us according to the US standard adopts aluminum alloy chain interlocking equipment, and its interlocking structure between layers ensures that the cable can withstand the powerful destructive force of the outside world, even if the cable is under great pressure. When impact force is applied, the cable is not easily broken down, improving the safety performance. At the same time, the armored structure isolates the cable from the outside. Even in the event of a fire, the armored layer enhances the fire-retardant and fire-resistant rating of the cable and reduces the risk factor of fire. The aluminum alloy armored armored structure is lighter than the armored armored steel tape and is easy to install. It can be installed without a bridge and can reduce installation costs by 20%-40%. According to the different places of use, different outer jacket layers can be selected to make the use of armored cable more extensive. 9. Compact pressure characteristics In terms of bulk conductivity, aluminum alloys are not as good as copper, but the conductors we developed not only improve the material properties, but also make major breakthroughs in the process. We use ultra-conventional compression technology. The coefficient of compression is 0.93, and the coefficient of compression of the profile line can reach 0.95, which is the first in the country. Through the larger extreme compression, it can make up for the lack of bulk conductivity of aluminum alloy cable, making the stranded conductor core as a solid conductor, significantly reducing the outer diameter of the core, improving the conductivity, under the same current carrying capacity. The outer diameter of the conductor is only 10% larger than the copper cable. We are factory which specializing producing and distribute hot melt Glue Guns.
