[ALUMINIUM NETWORK] Aluminum alloys used as conductors were cable replacement conductor materials that began extensive research in the 1960s and 1970s due to the rapid rise in copper prices. Aluminum alloys used as conductors mainly include AA1000 series, ie pure aluminum, AA6000 and AA8000 series conductors. AA1000 series conductors are mainly used in high-voltage overhead lines; AA6000 Al-Mg-Si (aluminum-magnesium-silicon alloy) series conductors are mainly used in high-voltage overhead lines and aluminum busbars; these two types of conductors are present in hard conductors and are connected by connectors. Welding is the mainstay. The AA8000Al-Mg-Cu-Fe (aluminum-magnesium-copper-iron-alloy) series is a soft aluminum alloy that is actually used on distribution lines.
In North America, the AA8000Al-Mg-Cu-Fe (aluminum-magnesium-copper-iron-alloy) series is only used in the low-voltage distribution network, but not in Europe. European countries basically use copper cables and pure aluminum. Cable solutions. European countries do not adopt the technical route of aluminum alloy cables. The reasons are mainly composed of the following aspects:
1. Comparison of Electrical Properties of Copper Core Cables and Aluminum Alloy Cables
Both copper and aluminum materials have significant differences in electrical and mechanical properties.
Aluminum alloy wire is similar to pure aluminum in terms of electrical conductivity and electrical resistivity, so the electrical performance of the copper cable can only be achieved by using an approach that increases the cross-section to 1.6 times that of the copper cable. This means that the aluminum alloy cable in the basic performance of the two electrical conductivity and resistivity point of view does not have substantial improvement than pure aluminum, which is the first reason why European countries did not choose aluminum alloy cable.
2. Comparison of copper core cable and aluminum alloy cable from the perspective of energy consumption
GP Hammond and CIJones [5] of the University of Bath conducted an in-depth comparative study on the energy consumption of different raw materials used in the power grid during production and use, as shown in Table 2. It can be seen that the energy consumption of aluminum metal during production and use is about 3 times that of copper.
Aluminum and aluminum alloy cables consume more energy than copper cables in production and use.
3, aluminum alloy cable carbon emissions and environmental impact is significantly higher than the copper cable
According to the comparative study of carbon dioxide emissions during production and use of different raw materials used in the power grid by GP Hammond and CI Jones of the University of Bath[5], as shown in Table 3. It can be seen that the metal aluminum emits twice as much carbon dioxide as copper.
In addition, WimBOONE of the Netherlands and ArnavKACKER of Germany pointed out in their article “A wide comparison of copper-cored cable conductors or aluminum-core cable conductors from a life-cycle perspective†that aluminum alloy cables have a higher environmental impact (acidification potential) than copper cables.
4, the full life cycle cost
The price of aluminum is far lower than that of copper, which makes aluminum alloy cables also have price advantages and brings profit margins for cable companies. However, European countries have compared the life cycle cost of cables and found that aluminum alloy cables and copper There is no obvious advantage compared to the conclusion of the cable.
Usually power cables can be used for 35 years to more than 50 years. However, cable investment decisions are primarily based on investment costs, while investment costs ignore the potential for cost savings in the life of the cable. The total cost of ownership of the cable (hereinafter referred to as "life cycle cost") should not only consider the initial cost of the cable, but also the operating and maintenance costs of the cable during its use. Therefore, the total life cycle cost should include the capital expenditures and operating costs within the cable lifespan. Only in this way can it be possible to choose more economically conductive materials such as copper and aluminum.
WimBOONE of the Netherlands and ArnavKACKER of Germany have reached the following conclusions in their Life Cycle Cost Analysis (LCCA) in their “Comparison of Copper-Conductor or Aluminum-Conductor Cable Leads from a Life Cycle Perspectiveâ€:
1) The cost difference between copper cable and aluminum cable has decreased significantly during its operation period. In all cases, the cost difference during the operation period is around 3%, and in some cases, the copper cable has even become a lower life cycle cost.
2) If you consider only one-time investment and procurement costs, aluminum alloy cables and aluminum materials will undoubtedly have great advantages, but from the life cycle cost analysis of copper and aluminum cables, the cost of copper and aluminum is almost no difference, and with aluminum alloy cables Comparison of copper cables from the perspective of full life cycle cost is better than aluminum alloy cables.
Conclusion: European countries do not adopt the technical route of aluminum alloy cables. They mainly conduct full research and demonstration on the electrical properties, energy consumption, carbon dioxide emissions, environmental impact, and life cycle costs of copper core cables and aluminum alloy cables. The conclusion that the aluminum alloy cable is not suitable for European countries.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
