1, armored features: 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 غير مجاز مي باشدts are quite high, Combined with poor corrosion resistance, the service life is not long. 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 غير مجاز مي باشدts by 20% to 40%. According to the different places of use, different outer jacket layers can be selected to make the use of armored cables more extensive.

2. Pressing characteristics: In terms of bulk conductivity, aluminum alloy is not as good as copper, but the conductors we developed not only improve the material properties, but also make great breakthroughs in the process. We use ultra-conventional compression. With the technology, the coefficient of compression is 0.93, and the coefficient of compression of profiled lines can reach 0.95, which is the first in the country. Through the maximum limit of the compaction, can make up for the lack of volumetric conductivity of aluminum alloy, so that the stranded conductor core as a solid conductor, significantly reduce the core diameter, improve the conductivity, under the same current conditions The diameter is only 10% larger than the copper cable.

3, Conductivity: The conductivity of aluminum alloy is 61.5% of the most commonly used reference material copper IACS, and the carrying capacity is 79% of copper, which is better than pure aluminum standard.

4. Creep resistance performance: The aluminum alloy conductor alloy material and annealing treatment process reduce the "creep" tendency of the conductor under heat and pressure, compared with pure aluminum, the creep resistance is improved by 300%, and the cold flow is avoided. Or creep caused relaxation problems.

5, 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 increased the tensile strength, and the elongation rate increased to 30%, Use more safe and reliable.

6. 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.

7, self-weight bearing capacity: aluminum alloy to improve the tensile strength of pure aluminum, aluminum alloy cable can support the length of 4000 meters 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).

8. Anti-corrosion performance: The inherent corrosion resistance of aluminum stems from the fact that when the aluminum surface is in 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.

9, flexibility: aluminum alloy has a good bending performance, its unique alloy formula, processing technology, so that 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.
