One minute to learn about bare copper wire!

For bare copper wire to start from the appearance of observation, in general, good bare copper wire appearance is brighter, no obvious damage and scratches, no obvious oxidation reaction caused by discoloration phenomenon, the outside color is relatively uniform, no black spots, no cracks, uniform distance, meet the above standards is a good copper choice. Secondly, the selection of bare copper wire specification model copper needs to observe the scale and specification of the line, the general copper brush must be within the specified range, can not exceed the process standard, otherwise, will be regarded as an invalid kink, the single line that constitutes the line must meet the characteristics of uniform and neat, in line with the process rules. Again, the selection of copper structure composed of bare copper wire structure also observes the distribution and composition structure of the structure, whether there are short wires, knotted wires, pine beads, strands, usually can be observed with the naked eye. We have to carefully observe the quality of copper, and we cannot select unqualified products to produce wires and cables, which will lead to serious safety accidents. From the copper welding process copper purchase, pay attention to whether the welding process is firm, whether the interface part of the welding is neat, whether the line is uneven, the interface of the welding should be maintained, polished flat, rounded, can not hold hands, the diameter of the welding head can generally not exceed 0.2 mm, the welding of the adjacent two copper wires should maintain a certain distance, the interval should be uniform.
Bare copper wire can be used as military coated conductor, power industry grounding pole, power cable braided network cable, various electronic component connectors, special cable reinforced conductive core, power transmission and telephone line overhead line, parallel dual-core telephone user communication line conductor, electrified railway, rail transit line bearing cable and sliding wire, cable TV user line and inlet coaxial cable inner conductor material computer LAN, access network cable, field cable inner conductor. The application of hard copper and soft copper S wire is different, hard copper wire resistance is relatively strong, so the resistance is small and the conductive function is good, often used in places that require electricity and high tension requirements, we commonly see household appliance wires, used as conductors of power lines and communication equipment in electrical appliances. Insulated copper wire has a wide range of applications, that is, there is an insulating adhesive or plastic outside the bare copper wire, this bare copper wire is mainly used to use the characteristics of high tension of copper, can be used for special locks, bicycle or battery, motorcycle brake wire, can also be used as a clothesline.
So what are the advantages of bare copper wire? Here's an introduction.
1. Copper plays the role of conducting weak electric signals, iron wire plays a supporting role, according to the method of copper wrapped with iron wire, it is mainly divided into electroplating, coating, hot column / water immersion, electroforming.
2. The use of bare copper wire can reduce the working temperature, compared with the same area of single strand, the mechanical flexibility of the wire is higher, and at the same time high-quality copper-plated tinned soft copper wire made of bare copper wire, after Renji treatment during processing, the finished product is soft, correct appearance, beautiful, the above is about its introduction, I hope to help you.
