Why use ACSR for high voltage power transmission?

Aluminum-steel-reinforced wire refers to a reinforced conductor in which single-layer or multi-layer aluminum strands are twisted outside the galvanized steel core wire. Mainly used in electric power and transmission line industry.
In the modern era of advanced science and technology, many industrial modernization facilities have appeared in our world and exist in our lives. Steel cored aluminum stranded wire is also the main force that plays an important role in electricity. Its inside is a steel core, and the outside is twisted with aluminum wires around the steel core; the steel core mainly plays the role of increasing strength, and the aluminum stranded wire mainly plays the role of transmitting electric energy. ACSR has a very simple structure, convenient erection, convenient maintenance, low line cost, large transmission capacity, and is also conducive to laying across special geographical conditions such as rivers and valleys. It has good electrical conductivity and sufficient It has the characteristics of excellent mechanical strength, high tensile strength, and the distance between tower rods can be enlarged. Therefore, it is widely used in overhead power transmission and distribution lines of various voltage levels.
In the case of such stable power transmission, why choose ACSR? It is stable enough in power transmission, but the energy loss and heat dissipation are not good. It can be used for ordinary power transmission, but the cost is relatively high, and large-scale application is hindered. However, high-altitude overhead lines, also known as ACSR, are still required for regional power transmission. Steel-cored aluminum stranded wire is the transportation material we use for high-voltage power transmission. It can have a good heat dissipation effect, because this kind of thing has a larger throttling surface and its shape is more of the original sheet type. And its power data transmission loss is smaller.
There will be a lot of loss in the process of power transmission. Therefore, in order to ensure high efficiency and low loss in power transmission in our power grid, this type is used. Because the structural surface is larger and the heat dissipation effect is better, it becomes an overhead line. It is the best choice for the so-called overhead line transmission, because it can exert a good transmission effect, and the high-voltage transmission line is high and will not cause any personal injury.
The power cable we use is stable enough, but it will cause too much energy loss, and its cost is relatively high. When the power is strong enough, it will melt because the current it can withstand is limited. So it is obviously not suitable for high voltage transmission.
For workers in the circuit installation industry, stranded wire is definitely an industrial raw material that is not unfamiliar, because the main application object of stranded wire is to act as a substitute for wires, and choosing a well-known steel-cored aluminum stranded wire can relieve buyers Many burdens to identify the quality of strands.

So what are the benefits of choosing ACSR?

(1) It can facilitate the subsequent maintenance of workers

Because the processing and maintenance steps of the stranded wire itself are very simple, because the shell of the stranded wire itself is made of steel as a raw material, it is easy to clean and wipe. After purchasing the steel-cored aluminum stranded wire, the customer can process the stranded wire very effectively but not cumbersomely. And maintenance, even if it is installed on a utility pole, it can easily scrub the outer layer.

(2) Can have a large amount of current transmission

Generally, stranded wire is one of the raw materials used to act as wires. At the same time, because its raw material is made of an alloy composed of steel and aluminum, it has a fairly rich electrical conductivity and can carry a large amount of current transmission. The quantity ensures the stability of the electricity, and making it into a wire or other conductive purposes can also play its role well.

(3) Has outstanding mechanical strength and electrical conductivity

Due to the hardness of the alloy, the steel-cored aluminum stranded wire has high mechanical strength during use and can bear a lot of weight. At the same time, because of the good electrical conductivity of its raw materials, it also has excellent electrical conductivity and can accommodate The transmission and matching of many voltages also has very strong tensile properties and can withstand changes in shape.
The high-quality stranded wire produced by the steel-reinforced aluminum stranded wire manufacturer can provide assistance for the buyer’s follow-up work. The choice of steel-cored aluminum stranded wire can not only facilitate the subsequent maintenance of workers without complicated maintenance procedures, but also have a large amount of current transmission, can withstand the passage of high-voltage current, and can have outstanding mechanical strength and electrical conductivity as a wire. better raw materials.
