The method and application of copper wire connection

According to wire conductor material, copper is the most widely used conductor material with large yield and relatively cheap. The advantage is that the resistivity is small and easy to process the full frequency conduction balance. The disadvantage is that common copper impurities are more stable in general. Because the brass wire is drawn into seamless copper pipe, soft quality, strong wear resistance, so it can be used for heat exchanger and condenser, low temperature pipeline, submarine transportation pipe; Manufacturing sheet, bar, bar, pipe, casting parts, etc.; Copper 62% ~ 68% plastic strong, manufacturing pressure equipment, etc.

Silver is a high quality conduction medium. The advantage is that the resistivity is very low and high frequency signal transmission is better than low frequency signal transmission. Disadvantages are not easy to process, poor stability.

Alloys generally include copper plated silver, copper coated silver, copper silver tin, copper silver gold and other alloys. The advantages are good stability and distinct personality can play a variety of metal advantages. The disadvantage is not easy to process.

Carbon fiber is the new conductor material, production is small, expensive. The advantages are environmental protection, stability is very good personality. The disadvantage is that the resistivity is slightly large and difficult to process.

The toughness of good copper wire is very good. Take a copper wire and bend it several times. If it breaks easily, it proves that the product is very bad. And the surface of copper wire usually has a thin layer of plastic skin, high-quality copper wire ignited after the surface will not appear open fire. Look at the core, if the core is in the center of the cable shows that the quality of the copper wire is better. If not in the middle, then when the power consumption is too large, it is easy to have a breakdown of safety accidents. When buying copper wire, we should pay attention to checking the length error of fine copper wire and the diameter error of cross section line. This is very important, the general length error is greater than 5%, indicating that the copper wire must have been tampered with by a small workshop.
