With the needs of our industrial production and life, we often need to use many Enameled Wire around us. These enameled wires bring great convenience to our production. As we all know, the quality of enameled wires has a great influence on our use. If we buy enameled wire products with poor quality, it will bring certain potential safety hazards to our use and even cause great economic losses. Therefore, we should master the skills of purchasing these enameled wires, which can facilitate our purchase.
First of all, the most important thing is to check the material of the product when purchasing. How to identify the material of enameled wire? For example, whether the insulation and sheath are elastic, whether there are burrs or protrusions on the surface, and whether the appearance should be smooth, round and uniform. Whether the copper-aluminum core can meet the requirements, the conductor resistance shall be tested when conditions permit. It is suggested that famous brand products produced by well-known enterprises should be purchased. These enterprises have strict quality control over their own products and guarantee the quality of their products to a certain extent. Pay attention to the product identification. When purchasing enameled wire, one should observe whether the certificate of approval of the product is complete in marking relevant information such as product model, specification, rated voltage, number of cores, production date, implementation standard, license number, etc. The physical surface of the product should be printed with continuous signs of the manufacturer name, product model and rated voltage, and whether the relevant information of the two is consistent should be verified.
The most important thing is that we should choose the right manufacturer, because there are really too many enameled wire manufacturers on the market now, and the quality of the products produced cannot be guaranteed. Therefore, for our consumers, if we cannot master the experience of judging the quality of these enameled wires, we will choose a more reliable manufacturer, thus to a large extent, we can ensure that the quality of the enameled wire purchased can be guaranteed to a certain extent and bring more safety guarantee for our use.
