We're also concentrating on improving the things administration and QC program to ensure we could maintain terrific gain from the fiercely-competitive company for Rectangular Profiled Litz Wire, High Temperature Adhesive Winding Wire, Polyurethane Coating Enaemled Copper Winding Wire, We wholeheartedly welcome customers all over the world come to visit our factory and have a win-win cooperation with us!

Super Lowest Price Magnet Wire - 0.038mm Class 155 2UEW Polyurethane Enameled Copper Wire – Ruiyuan Detail:

Main test items: pinhole test, minimum withstand voltage, tensile test, maximum resistance value.
Test method for pinhole test: Take a sample with a length of about 6m, immerse it in 0.2% saline. Drop an appropriate amount of 3% alcohol phenolphthalein solution in the saline and put 5m long sample in it. The solution is connected to the positive electrode, and the sample is connected to the negative electrode. After applying 12V DC voltage for 1 minute, check the number of pinholes produced. For enameled copper wire below 0.063mm, take a sample of about 1.5 meters in length. Only 1m long enameled wire needs to be put into the saline.

1.It features good solderability (self-soldering)and is solderable after completion of winding. Even at 360-400 degrees, the wire has great and prompt soldering property. There’ s no need to go on with mechanical stripping of enamel, contributing to increase of working efficiency
2. Under the condition of high frequency, it’ s characterized by good “Q” value.
3. Great adhesion of enamel is convenient for winding. Insulating property can remain well after winding.
4. Solvent resistance. Dyes can be used to change the color of enamel for identification. Colors that we can produce for Polyurethane enameled copper wire are red, blue, green, black and so on.
5. Our advantages: goal of “zero” pinholes after stretching. Pinholes not in compliance with standard are the main cause of short circuits for electronic devices. For our products, we set a goal to achieve “zero” pinholes after stretching by 15%.
