For those engaged in the cable industry, the production materials and manufacturing processes of drag chain cables are crucial, among which, the most important metal material to be used is copper. On the market, we can see a lot of cables produced with aluminum or silver, then whether these two metals are also suitable for tow chain cables? The following Yi Chu cable will tell you about the mystery of this.

Copper and aluminum two metals have a common "light", in addition to the price is relatively cheap, manufacturers in the selection of conductor materials in addition to considering cost factors, more important is to consider whether the material is "usable". We all know that the tow chain cable is moving back and forth in the tow chain, so the conductor material needs to have good ductility, and the ductility of aluminum is very poor, it is easy to break more than one bend, according to the normal use requirements, the life of the tow chain cable is 5 million cycles, and there are 3 million cycles just short. The use of aluminum as a conductor material may be scrapped in less than 1 million cycles.

In addition, the current carrying capacity of "aluminum" is also very low, if you want to achieve the same level of "current carrying capacity" needs a larger cross-sectional area, and the large cross-section of the cable chain requirements are higher, so the cost of buying the cable chain seems to reduce the actual increase.

The conductor design requirements of the tow chain cable are very detailed, so its toughness is very excellent, which brings great flexibility for use, and also saves the placement space of the tow chain cable. The copper material has excellent propagation properties and low price, and the strength is also guaranteed, which can be adapted to long-term recycling.

However, it is worth noting that copper also has a disadvantage of oxidation, and in daily production, it is necessary to reduce the probability of copper conductor oxidation as much as possible. For example, transparent plastic film sealing measures are adopted for copper metal, appropriate copper wire drawing process is adopted, and passivation treatment technology is adopted for copper wire stranding and extruded insulation processes.

Therefore, whether from the perspective of enterprise cost or cable quality, the application of metal copper has become a consensus in the industry, enterprises in the purchase of cable, in addition to pay attention to whether the use of copper material, but also to observe whether the quality of pain is guaranteed, high-quality copper surface has metallic luster without impurities, Impurities and oxidized copper will greatly reduce the service life of the tow chain cable.
