Patent CN202211198053X discloses a device for preparing ceramic-insulated aluminum coil, which is to pre-bend aluminum wire into spiral screw into oxidation tank for oxidation treatment, and then to naturally form ceramic-insulated aluminum coil after treatment.

The oxidation tank 4 is internally provided with a cathode plate 401 and electrolyte, and the cathode plate 401 and an aluminum wire 5 are respectively connected with a micro-arc oxidation/thermoelectric chemical oxidation power supply. The aluminum wire 5 is oxidized into a ceramic-insulated aluminum coil while passing through the oxidation tank 4. The lead-in wheel 1 is a conductive copper wheel, and the aluminum wire 5 is connected with electricity through the conductive copper wheel. The oxidation tank 4 is made of insulating material (PVC), and even if the aluminum wire 5 extending into the oxidation tank 4 is deformed to contact with the side wall of the oxidation tank 4, short circuit does not occur.
