1. Packaging Good roller packaging can reduce insulation wear during production, transportation and handling, and facilitates electrical installation. There is a complete certificate in the package. The certificate should include complete information such as specifications, execution scale, rated voltage, length, date, and factory name.
2. Whether the wire package has the “CCC†and the production license number of China's national compulsory product certification; see if there is a quality system certification; see if the certificate is standardized; see if there is a factory name, site, chapter, date of production; Look for the trademarks, specifications, and voltages printed on the wires. It also depends on the cross section of the wire copper core. The superior product has a bright copper color and soft luster, and the copper core is reddish yellow, indicating that the used copper material is of good quality, while the yellow and white hair is a reflection of the low quality copper material.
3 check the size of the wire must see its length and core thickness have not done limb movements. Delineated in the relevant scale, the error of the length of the wire cannot exceed 2%, and the diameter of the cross-section cannot exceed 0.02%. However, there are a lot of short-cuts in length on the market, and fraud in the cross-section (if the cross-section is 2.5 square millimeters) The line is actually only 2 square millimeters thick.
4. Look at the color of copper Qualified copper core wire copper core should be purple, shiny and soft to the touch. The shoddy copper wire copper core is purple black, yellowish or white.
5. Look at the insulating rubber The counterfeit wire insulation looks like a very thick, in fact most are made of recycled plastic, as long as squeezed a little force, the extrusion will be white, and powder falling. 3. The weight of the wire. Good quality wires are generally within the designated weight range. For example, a plastic insulated single-stranded copper wire with a cross-sectional area of ​​1.5 mm2 is commonly used, and the weight is 1.8 to 1.9 kg per 100 m.
