[China Aluminum Network] For the electromechanical installation industry, wire and cable occupy an important position in the electromechanical installation project. As its main raw material, copper accounts for 70%~80% of the total cost of cable products, and the price of copper cables will increase. The rapid increase in copper prices has brought great difficulties to investors and contractors in terms of project cost control. For this reason, the research and application of copper-clad...

[China Aluminum Network] According to the different conductors of the internal conductor, there are two main types, one is pure copper material, one is copper clad aluminum material. The copper clad aluminum is: Copper Clad Aluminum, so the copper clad aluminum conductor is often called: CCA conductor. The copper-clad aluminum composite wire was first introduced by Germany in the 1930s, and was subsequently promoted in the United Kingdom, the United States, and France, and was widely used in...

[China Aluminum Network] Electrolytic corrosion occurs when copper conductors are connected to aluminum conductors in power lines. When the copper wire and the key wire are connected. Due to different materials. There is a certain potential difference between each other. The potential difference between copper and aluminum is approximately 1.7V. If water vapor is present, electrolysis will occur, and the contact surface will be gradually eroded and oxidized, resulting in poor contact of the...
[China Aluminum Industry Network] mainly has the following three major reasons: The chemical and physical properties of copper and aluminum are very different So copper and aluminum should not be directly connected. Of course, the copper-aluminum connection is unavoidable. When a connection is required, a copper-aluminum transitional wire clip, a copper-aluminum transitional connector, a copper wire or a tin wire or a tin wire are directly connected. The electrochemical properties of the two...
In a sense, the wire and cable manufacturing industry is a material finishing and assembly industry. First, a large amount of material, the cost of materials in the cable products account for the production of cable 80-90% of the total cost; Second, the types of materials used, the type is very large, high performance requirements, such as conductor copper, copper The purity should be above 99.95%, and some products require the use of oxygen-free high-purity copper. Thirdly, the selection of...
History The first recorded attempt to make copper clad steel wire took place in the early 1860s, according to the Copper Clad Handbook, issued by the Duplex Metals Co., Chester, PA at the turn of the 20th century. Although for over 100 years people had been suggesting various ways of uniting copper and steel, it was not until the period mentioned that Farmer and Milliken tried wrapping a strip of copper about a steel wire. American engineers in 1883 and again in the 1890s made attempts to...
The connection between the wire and the wire, the connection between the wire end and the terminal block, the matter is small and the responsibility is large. This article is illustrated, so that you can clearly understand! Wire to wire connection The connection of the wires is: straight connection of single-strand copper conductor, T-shaped connection; docking of double-strand; straight-line connection of multi-strand copper conductor, T-shaped connection; docking of unequal-diameter copper...
A team of microbiologists from Amherst, Massachusetts, USA, has found a new way to create bio-wires 6000 times thinner than human hair called "microbial nanowires." The researchers said that the microbial nanowires are made of genetically modified soil bacteria, Sulfur-Reducing Bacteria, which have a diameter of 1.5 nanometers, about one-sixth of that of human hair, but have a 2000-fold increase in conductivity , And very durable. Dr. Derek R. Lovley, principal investigator of the research...
The difference between wire and cable is that the size of the wire is generally smaller. The conductor with a larger cross-sectional area (greater than 6 mm2) is called a large wire and cable, the smaller (less than or equal to 6 mm2) is called a small wire, and the insulated wire is Called cloth wire. However, cables are sometimes classified as broad wires. Method of distinguishing wires 1 Wire: It is composed of one or more soft wires, and the outer bread is made of a light and soft sheath,...
