The electrical properties of aluminum alloy cable which wrapped by copolymer coated aluminum
Jan 23, 2018

In modern life, the development and application of cable is becoming more and more popular. The aluminum alloy cable has shown great superiority, and the copolymer coated aluminum plays an important role as an important structure of cable part. Next, we will simply analyze the electrical properties of aluminum alloy cable which wrapped by copolymer coated aluminum.


First of all, to analyze the flow of aluminum alloy cables. In fact, there are many factors affecting the interception of aluminum alloy cables. Comparatively speaking, when the cross-sectional area of aluminum conductor is 1.5 times of that of copper conductor, the electrical conductivity of alloy conductor and copper conductor is the same, achieving the same current carrying capacity, resistance and pressure loss. The resistivity of aluminum alloy is between aluminum and copper, slightly higher than aluminum, but lower than that of copper. Under the same cutting volume, the weight of aluminum alloy conductor with the same length is only half of that of copper.


Of course, there are many other factors to be considered at the same time. For example, the characteristics of the line, the aluminum plastic composite belt is used in the structure of the aluminum alloy cable itself, the actual laying conditions and so on. In addition, if the highest operating temperature of the conductor is allowed to differ from the ambient conditions, it will also have different effects.


Secondly, the copolymer coated aluminum tape can effectively reduce the outer section of the cable on the aluminum alloy cable. In the process of producing and processing aluminum alloy cables, the most advanced compression technology will be adopted so that the filling coefficient of the conductor can reach 91 to 93%. In addition, the aluminum alloy cable use silane crosslinked polyethylene, so only 2/3 thickness of PVC can far exceed the conventional insulation performance.


Finally,  the copolymer coated aluminum tape can obviously reduce the loss of the cable on the aluminum alloy cable. This is because there is no eddy current in practical applications, so it can reduce the loss of the line. Even if there is a three-phase unbalanced current, the loss of lines of aluminum alloy cable which is wrapped by copolymer coated aluminum is still very little.http://www.copolymercoatedaluminumtape.com/
