According to the skin effect, when the AC frequency reaches 5MHZ, the AC resistance of using copper clad aluminum is exactly the same as using copper, that is to say, using the same wire diameter as the copper wire at this time will not affect its electrical performance. 3. When the frequency of the alternating current reaches 5MHZ, the influence of the resistance is completely negligible. What should be paid attention to when changing copper to aluminum?1.Therefore, the original copper wire welding process and materials are used. When the frequency of the alternating current is higher, the influence of the resistance of the copper clad aluminum will be less and less.2.Tinning is impossible, so the connection must be aluminum Special solder materials and processes for covered wires. Wire slot design changes (wire diameter difference) In order to ensure the resistance of the original conductor, which leads to the conductor wire diameter At the same time, the full rate of the slot is Polyester Enameled Copper Wire suppliers also increased to a certain extent. It can save a lot of costs, improve the competitiveness of products, and increase considerable economic benefits for the enterprise. Wire diameter change (because of the difference in conductor resistivity) Aluminum wire diameter = copper wire diameter 3. Changes in 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. The performance of the product meets the requirements of the market.What are the advantages of using copper clad aluminum enameled wire? 1.. 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.
