Copper-clad aluminum conductor wire and cable use range and product characteristics
Use range: Polyvinyl chloride insulated wires and cables with rated voltages of 450/750V (below 1Kv) and below, suitable for fixed installations of lighting and electrical power devices with AC rated voltages of 450/750V and below, and power transmission and distribution systems below 1Kv. For use. It is widely used in electric power, construction, mining, metallurgy, petrochemical, transportation and other sectors. In a good use environment, it can be used continuously within the rated voltage and current levels, and the service life is the same as that of the copper cable. Features: 1) It has good corrosion resistance and low conductor contact resistance. Under normal circumstances, aluminum is more corrosive than copper, but because the aluminum of copper-clad aluminum is completely covered by copper, the weaknesses of aluminum conductors such as easy oxidation and large contact resistance are improved. 2) It has good solderability. The copper clad aluminum wire is coated with a layer of pure copper, so it has the same solderability as pure copper wire. It avoids the hidden dangers of the aluminum core cable being corroded, bumped, or due to poor compression and tin-free soldering, causing poor contact between the conductor and the terminal, and heating, which may cause the broken part of the cable to burn. 3) Light weight, soft thread, easy to process, easy to install and transport. 4) Copper-clad aluminum material has the advantages of relatively low cost and relatively stable price, which overcomes the disadvantages of high cost and price fluctuations of copper materials. 5) Compared with pure copper conductors, copper-clad aluminum has the advantages of pure copper conductors. Under the same conditions that the DC resistance of the conductor is the same as the DC resistance of pure copper (the cross-sectional area is larger than that of pure copper), its AC resistance is smaller than that of copper. , The current-carrying capacity is 2%-5% larger than the copper conductor (the larger the cross-sectional area, the more obvious the effect). The cable loss, temperature rise, high-order harmonics and other technical indicators are better than copper conductor cables. When connected with the same copper terminal, the temperature rise at the joint is lower than that of copper. Specification: 0.12MM to 2.5MM Use: used for braided cable protection, shielding, transmission of electronic signals, grounding release, etc. Has the following advantages: 1. The inner core is made of aluminum-magnesium alloy and the copper-clad bimetallic wire has the characteristics of low density of aluminum and good electrical conductivity of copper. 2. The copper-clad aluminum-magnesium alloy wire series products produced by our company have a specific gravity of 2.75g/㎝3, which is 3.2 times that of copper wire!
