Electrical is a product that is commonly used in our lives, because its appearance greatly facilitates our lives. In order for the appliance to function properly, we need the help of wires, which are the most common items in our lives. Wires are important equipment for power transmission. In the development of electric wires, we have a variety of wire and equipment, and the upgrade and replacement of wires is also very fast. Enameled Wire is a relatively common wire. It is very useful. Let us introduce how to distinguish the quality of enameled wire.
The enameled wire refers to a wire mainly composed of an aluminum core wire and coated with a certain proportion of copper layer on the outside. The main function of this type of wire is to transmit signals, which can be used as a conductor for coaxial cables, and as a conductor for wires and cables in electrical equipment such as home audio connectors. However, since aluminum has only two-thirds of the conductivity of copper, once the wire is used, the temperature of the wire rises, which poses some potential safety hazards and is more dangerous for underground and closed projects.
Therefore, national standards stipulate that all wires and cables used to transfer electrical energy require the use of annealed copper wires that are not plated with metal or metal as conductors, and aluminum wires, including enameled wires, are prohibited as conductors. As a conductor material, aluminum has many advantages, but it also has its inherent disadvantages: it is easily oxidized, has large contact resistance, cannot be soldered, and is more corrosive than copper, resulting in copper being replaced by aluminum.
Several methods for identifying the quality of enameled wire are briefly introduced above. I believe that after reading the above, everyone will have their own unique understanding, because the single material wire does have many shortcomings, which can be well avoided by this combination or alloy material wire. It combines the advantages of these two materials, if necessary, we can choose our Enameled Copper Wire manufacturers for purchase and consultation.
