Compare to copper cables, aluminum alloy has 30% higher flexibility and 40% lower rebound. The conduit size will often remain the same, but it still must be checked on a case-by-case basis. In utility applications, aluminum has a long-standing track record, and it continues to provide substantial performance in commercial and institutional applications. material, which allow the current to pass through them. For this reason, the conductor must be cleaned with a wire brush to remove this oxide layer, and then an antioxidant joint compound such as NOOX or Penetrox must be applied to keep the oxide layer from subsequently forming. Procedures Equally important is the implementation of quality control procedures and their equivalent documentation. This limitation can be overcome by running aluminum to the disconnecting means and running copper to the motor. about 1.6 times higher than copper. Installation criteria does exist to ensure the proper operation of the electrical distribution system in question. MC cable with aluminum feeders is becoming a staple in many high rise buildings, stadiums, shopping malls, commercial buildings, wastewater treatment, and manufacturing facilities. Its resistivity is 2.8X10pow(-8) ohm-m, i.e. Maine de Biran : The Philosopher in History, LIST OF IEEE .NET - MOBILE COMPUTING PROJECT TITLES, LIST OF IEEE JAVA IMAGE PROCESSING PROJECT TITLES. It's no wonder that more engineers are examining the possibilities and functionality of aluminum wiring. This is because aluminium wires have lower tensile strength than In the Canadian Electrical Code Table 5C denotes derating for the number of conductors. Tel: 0086 771 5592086 very low electrical resistance and are available in a large variety having All of these new alloys, particularly the 8000 series, have better conductivity, creep resistance, strength, and workability than previous aluminum alloys. aluminium is much lighter than copper. Contractors are installing them in service entrance conductors, large conductors, and power distribution conductors. If you need, welcome to choose us. Due, to Really nice post. These savings can reach up to 70 percent if aluminum is utilized in every possible way. First and foremost, a proper stripping tool should be used to avoid damage to the conductor. There are steps that must be taken to ensure proper installation when using aluminum: Design Criteria Another design issue challenge is that aluminum cannot be used to directly terminate to motors due to the current UL listing limitation on motors. Also the number of valence electrons Interstates is pleased to have recognized that the availability of alternative materials gives us another opportunity to examine what is in the marketplace, and we strive to be of service to our clients in determining the value for them based on their unique facility needs. Today, aluminum cable is commonly compact stranded, which compensates for some of this loss in conductivity due to a tighter packing of aluminum strands per cable diameter. However for applications like winding of Conclusion As with any major change, there are risks involved in selecting the aluminum for your design. We also offer preventative maintenance programs to reduce the risk of increased service calls that lead to downtime. The potential of using aluminum conductors from feeders to panel boards is also available, provided space considerations for the panel board terminations are met. Thermal expansion coefficient is used to calculate the size of the change in temperature of the material. In some systems this could prove to be a disadvantage … Where Aluminum Can Be Utilized Interstates recommends trying aluminum conductors from transformers to switchboards in service entrance applications and also installing the conductors from switchboards to motor control centers in feeder applications. Since industrial applications are considered Interstates' main area of expertise, we have conducted research on using aluminum conductors as an alternative to copper. panelboards. Annual follow-up inspections would also be an extremely good practice to employ. A common ampacity limit is 100amps but larger limits are being used by different specifiers. See the newest edition of the National Electric Code for more details. Interstates does not recommend every project utilize aluminum conductors, and we realize the use of aluminum in industrial projects would be a major change for many of our clients. The way you elaborated the advantages & disadvantages of both conductors is really good and easy to understand. Its resistivity is 2.8X10-8 ohm-m, i.e. This price jump has heightened the urgency and need for solid research on the topic of alternative conductors. Like copper, aluminium also forms an oxide layer over its surface when Aluminum vs Copper Conductors: Pros and Cons of Both; May 31, 2019 admin Home Electrical Leave a comment. Advantages of aluminium as compared copper as a It is rightly said the cost of copper conductor is more than that of aluminum. Mechanical connections are not a favorable connection type because of the expansion properties of aluminum. It is currently being successfully installed in many industrial applications. Besides the 8000 series, there are several other good options to choose from. Advantages of aluminium as compared copper as a If aluminum is used as a conductor material, its lower conductivity requires a wire size that is approximately one-third larger than that of a copper wire. lines. Doing so will reduce the current-carrying capacity through deformation and cause a hot termination. This contributes to easier construction installation methods, i.e. Aluminum alloy has good flexibility; its unique formula and processing technology greatly improve its flexibility. These various uses demonstrate that choosing aluminum is not a "novel" concept and it has been proven to be a useful, high-performing material. Aluminum conductors are going to be larger than that of a comparable copper conductor. We are currently experiencing a historic rise in copper pricing (a substantial 85 percent increase in the last year!). Technical Design Advances Many of the historical "horror" stories associated with aluminum can be attributed to technical design problems of the older alloys that have now been overcome by better product design or can be addressed by quality installations. What Are the Advantages of Aluminum Alloy Burglar Mesh? Its resistivity is 2.8X10-8 ohm-m, Keywords: Aluminum Profile, Industrial Aluminium Profile, Aluminium Extrusion, Aluminium Window & Door Frames, Curtainwall, Wire & Cable, Advantages and Disadvantages of Aluminum Alloy Cables, How to Examine the Quality of Aluminum Doors and Windows, Brief Introduction of Aluminum Curtain Wall, Improvement of Energy-saving for Aluminum Doors & Windows, Major Measurements of Aluminum Doors & Windows, Six Tips to Maintain Aluminum Alloy Doors and Windows, How to Choose High Quality Aluminum Alloy Doors & Windows. Copyright © 2018-2021; All Rights Reserved. When aluminum expose to the air, it will form the oxide layer, it is the inherent corrosion resistance of aluminum, and the oxide layer can resist any kind of corrosion. The copper and aluminum alloy have equivalent coefficient. However, some vendors disagree, claiming field electricians have more trouble with using the wrong dies in crimpers than with misusing the mechanical connectors. (BS) Developed by Therithal info, Chennai. bending, pulling cables, training of cables in tight enclosures, etc. Raceway sizes need to be checked and often increased; it is usually necessary to increase the conduit sizes on about 5 to7 percent of runs. Huadong OPGW cable will satisfy you. Examples are copper, brass, aluminium, silver, gold, bronze, etc, Portable Data Acquisition SysTem (PDAT): Making Ideas Reality. The client must weigh the pros and cons of aluminum vs. copper and ultimately make a decision based on each of their propositions. When connections are made correctly, aluminum conductors actually run at a lower resistance, and therefore a lower temperature, than copper conductors. electrical machines and transformers, it is difficult to substitute aluminium Section 310.14 states that aluminum conductors "shall be made of an AA-8000 series electrical grade aluminum alloy conductor material." For those who don’t know about conductors, insulator, and sheath. Because of the smaller cross-section of copper conductor cables compared with aluminium conductor cables , copper conductor cables
