Inquiry:
Enamelled aluminium wire is widely used in electrical products and household appliances, such as motors, electrical appliances, electrical instruments, telecommunications devices, and windings and components. However, as enameled aluminium wire is further replaced by enameled copper wire, the market has higher requirements for the characteristics of enameled aluminium wire products. According to the current national standard of the People's Republic of China GB/T 23312.5-2009, enameled aluminium wire with 200-grade polyesterimide enameled aluminium wire Chapter 14, enameled continuity (salt water pinholes) standard can not meet the higher technical requirements for enameled aluminium wire. Now many electrical appliances. The technical requirements for film continuity of enameled aluminium round winding wires are more than 10 times of the national standard GB/T 23312.5-2009 of the People's Republic of China. Henan Signi Aluminum has developed enameled aluminium round winding wires to meet the requirements of higher technology for film continuity.


 
The coating method of polyesterimide 200 grade enameled aluminium round wire for motor. The coating method includes the following steps: (1) cleaning and annealing the aluminium circular wire, the annealing temperature is: annealing upper 400 ℃, annealing middle 390℃, annealing lower 380 ℃; (2) painting: first coating the primer layer, the thickness of the primer layer is 0.010-0.048 mm; then coating the primer layer, the thickness of the topcoat layer is 0.003-0.060 mm; (3) baking: baking furnace inlet temperature is 375-385 ℃, baking furnace. The core temperature is 445 - 455 ℃, and the outlet temperature is 485 - 495 ℃. (4) Cooling, lubrication, wiring, quality inspection and packaging.
 
The  polyesterimide 200 grade enameled aluminium round wire made by Henan Signi Aluminum has low production cost and excellent performance in heat resistance, deterioration resistance and film continuity.
