The wire and cable manufacturing industry is, in a sense, a material processing and assembly industry. Firstly, there is a huge amount of material used, with the material cost of cable products accounting for 80-90% of the total manufacturing cost. Secondly, there are various types of materials used, with particularly high performance requirements. Copper used for conductors requires a purity of over 99.95%, and some products use oxygen free and high-purity copper. Thirdly, the selection of materials has a decisive impact on the manufacturing process, product performance, and service life.




At the same time, the interests of wire and cable processing enterprises are closely related to whether materials can be scientifically saved in material selection, processing, and production management. Therefore, the design of wire and cable products must be carried out simultaneously with material selection, usually selecting and specifying multiple materials after process and performance screening.




There are a wide variety of materials, grades, and specifications (grades) used to manufacture cable products.

So, how to choose high-quality wires? Huanshi the Pearl River Cable has sorted out the following points:




1. Check the packaging




Check the complete certificate in the packaging box, which should include complete information such as specifications, performance standards, surge voltage, length, date, factory name and address. Verify the existence of the CCC product certification certificate and production license number; Check the quality system certification; Check if the certificate is standardized; Check if the trademark, standard, voltage, etc. are printed on the wire.




2. The relevant standards stipulate that the error in wire length shall not exceed 2%, and the cross-sectional wire diameter shall not exceed 0.02%. However, there are many phenomena of short-term fluctuations in the cross-section in the market




3. Look at the color of copper




Qualified copper core wire should be purple, glossy, and have a soft touch. The copper core of the fake copper core wire is purple black, light yellow, or white.




4. Check the insulation adhesive




The insulation layer made of counterfeit and inferior wires looks very sturdy, but most of it is actually made of recycled plastic. Rub vigorously, the kneaded part will turn white and powder will fall out.




5. Check the weight of the wire




High quality wire is generally within the specified weight range. For example, the commonly used plastic insulated single core copper wire with a cross-sectional area of 1.5mm2 weighs 1.8-1.9kg per 100m.




The materials of cable products can be divided into conductive materials, insulation materials, filling materials, shielding materials, sheath materials, etc. according to their usage location and function. However, some of these materials are universal for several structural components. Especially thermoplastic materials such as polyvinyl chloride and polyethylene can be used for insulation or sheathing, as long as some formula components are changed.
