What are the precautions for the three-layer insulated wire of high-frequency transformer?

 Today, the three-layer insulated wire of Dongguan Juke High frequency transformer is a kind of high-performance insulated wire. Do you know what are the precautions for the three-layer insulated wire of high-frequency transformer? The wire has three insulating layers, the middle is the core wire, the first layer is a golden yellow polyamine film, the second layer is a high-insulation spray paint coating, and the third layer is a transparent glass fiber layer!
 
The following points are noted in the use of high-frequency transformer three-layer insulated wire in Dongguan Juke Industrial:
 
1. The three-layer insulated wire in the high-frequency transformer is reinforced by the film. If the film is severely deformed or damaged due to mechanical stress or thermal stress, the safety standard cannot be guaranteed; there should be no burrs on the transformer skeleton, and the corner portion of the contact wire should be rounded (chamfering), and the inner diameter of the outlet nozzle should be The outer diameter of the wire is 2~3 times; the end of the cut wire is very sharp, and should not be close to the wire film.

2. There are two types of devices for welding three layers of insulated wires. One is a static solder bath suitable for soldering three layers of insulated wires below 4.0 mm. When soldering moves horizontally in the solder bath and vibrates the bobbin, the welding can be completed in a short time. Another type of welding device is an air-cooled spray-type solder tank, which can simultaneously weld a plurality of coil bobbins and is suitable for mass production.

 3. When peeling off the film, special equipment such as three-layer insulated wire stripping machine and adjustable stripping machine should be used. It is characterized in that the film is melted while being peeled off, so that the wire is not damaged. If an ordinary wire stripper is used to strip the insulating film, the wire may be thinned or even broken.

4. The storage condition of the three-layer insulated wire is that the ambient temperature is -25~30 degrees Celsius, the relative humidity is 5%~75%, and the storage period is one year. It is forbidden to store three layers of insulated wire under high temperature, high humidity, direct sunlight and dust. For the three-layer insulated wire that exceeds the storage period, the insulation breakdown voltage, withstand voltage, and the windability test must be re-executed before use.
