Aluminum wire takes on heavy responsibilities, saving energy and reducing worries
In our daily life, wires and cables are everywhere, delivering electricity to various electrical equipment. However, among the many wire and cable materials, aluminum wire is often overlooked, but it actually hides many advantages. Whether in the high-rise buildings in the city, the fields in the countryside, or behind the electrical appliances in our homes, aluminum wire plays an important role silently. Today, let's take a deep look at the secrets of aluminum wire.
Aluminum wire has a thousand connections with other wires and there is also fierce competition. Next, let's take a look at what is unique about aluminum wire compared to other common wires. Copper wire can be described as a "star product" in the field of wires and cables, and is often regarded as a representative of high quality. In terms of price, aluminum wire has an absolute advantage. The price of aluminum is relatively low, which makes the cost of aluminum wire much lower than that of copper wire. Therefore, in large-scale power projects, the use of aluminum wire can greatly reduce costs. For projects with limited budgets, aluminum wire is a more economical choice.
Aluminum wire, with its unique properties, has been widely used in many fields and has become an important force in promoting the development of various industries. Aluminum wire is widely used in long-distance power transmission and high-voltage power transmission lines because of its good electrical conductivity, second only to copper, and its relatively low price and light weight. Moreover, aluminum can quickly react with oxygen in the air to form a dense aluminum oxide protective film. This protective film can effectively prevent the aluminum wire from further oxidation and corrosion, so that it can maintain good performance and a long service life in harsh environments.
However, compared with copper wire, aluminum wire has a higher resistivity, which means that under the same conditions, aluminum wire has weaker electrical conductivity and greater resistance loss when passing current, resulting in more power loss. The mechanical strength of aluminum wire is not as good as that of copper wire and some alloy wires, and the texture is relatively soft. It is more likely to deform or even break when pulled, bent or vibrated by external force. The chemical properties of aluminum wire are relatively active. When it comes into contact with air, oxidation reactions are easily induced at the joints to form a layer of aluminum oxide film. The resistance of this film is relatively large, which will increase the resistance at the joint, resulting in poor contact, causing problems such as heating and sparking, and even causing a fire in severe cases.
Aluminum wire, this seemingly ordinary metal wire, plays an indispensable role in our lives and industrial production. It provides strong support for the development of various industries with its advantages such as low cost, light weight, good corrosion resistance, good conductivity and excellent processing performance.
