Key Points About Enameled Aluminum Wire
Body
The precautions and points of enameled aluminum wire are as follows:
- Precautions for replacing copper with aluminum
- A) Wire diameter change (due to the difference in conductor resistivity) Aluminum wire diameter = Copper wire diameter × K
K is the value of the empirical coefficient based on actual application.
- B) Design change of wire groove (different wire diameter)
In order to ensure the resistance of the original conductor, this will result in an increase in the diameter of the wire and an increase in the gap-filling rate.
- C) Variation of winding (difference in tensile strength)
Aluminum has worse toughness than copper, so it is necessary to reduce the winding tension and appropriately reduce the winding speed.
- D) Change in connection method (difference in welding performance between copper and aluminum)
Compared with copper, aluminum is very easy to oxidize and welding is very difficult. Therefore, it is impossible to use tin in the original copper wire welding process and materials, so the connection must use special welding materials and processes for enameled aluminum wire, and then welded into round enameled aluminum wire or Rectangular Enameled Aluminum Wire according to the shape requirements Aluminum wire.
