The use of aluminum profiles as conductors

Driving trolley line selected as the advantages of aluminum conductors

with the requirements of industrial and economic development, more and more development along the energy-saving equipment environmental protection. At present, the single-pole combined type trolley trolley wire is commonly used in major enterprises, and its trolley wire conductor is made of aluminum. The main reasons for choosing aluminum as the conductor are:

1. Aluminum has good electrical conductivity;

2. The cost performance of aluminum is relatively high;

3. China's aluminum production can meet production requirements;

4. Aluminum is not easy to rust, easy to maintain and so on.

So why choose aluminum instead of pure aluminum as a conductor line conductor? Some people will ask such questions. Xiao Bian will explain it to you today:

First, aluminum mechanical strength is high. The mechanical strength of pure aluminum is not high, and it is easily deformed. This restricts the application of pure aluminum to some extent. Because, adding appropriate amounts of metal materials such as magnesium, copper, zinc, etc. to pure aluminum to make aluminum alloys of various brands can greatly increase the mechanical strength of aluminum, and thus the range of its use will be greatly increased.

Second, aluminum layout more coordinated. The higher the general purity of aluminum, the better its corrosion resistance, because aluminum in the air and oxygen oxidation, the formation of a layer of dense oxide film on the aluminum surface as a protection, effectively prevent the air and moisture corrosion of the internal conductor, aluminum profiles With the same features as above, besides, painting treatment can also be carried out, so that the color is diversified and the layout is more arbitrary.

Third, in the aluminum profile embedded a stainless steel belt, greatly improving the wear resistance, greatly extending the life of the trolley line.
