Enameled Copper Round Wire
Enameled copper round wire is made of high purity copper with round cross-section, coated with insulating materials such as polyurethane, polyetherimide or polyiodide, and baked and cured at high temperatures to form insulated wires with good electrical insulation, mechanical properties, thermal properties and chemical properties.
Enameled copper round wire core characteristics
a) Electrical properties: high insulation (its breakdown voltage can reach thousands of volts).
b) Temperature resistance: temperature resistance grade is divided into class B (130 ℃), F (155 ℃), H (180 ℃ - 240 ℃), etc., to adapt to various types of high temperature and low temperature of different working environments.
c) Mechanical strength: the paint film is flexible and scratch-resistant, suitable for automatic winding equipment.
d)Chemical stability: resistant to solvents, humidity and some chemical corrosion.
Size: 0.050-2.600 mm (diameter)
Conductor: Copper (purity > 99.97%)
Heat resistance grade: 130/155/180/200/220/240 grade
Lacquer film thickness: Class 1 (thin lacquer) to Class 3 (thick lacquer)
Coating: PEW, UEW, EIW, PAIW, EIW+PAIW, PEW-NY, etc.











1. Q: How fine can the minimum diameter of enameled wire be
A: The smallest diameter of enameled wire we produce can be up to 0.060 mm. We adopt intelligent process control to ensure that excellent insulation and high temperature resistance can still be maintained under the demand of high precision, which is widely used in the fields of clicks, electrical appliances, new energy vehicles, 5G communication and so on
2. Q: How to ensure the quality stability of enameled wire
A: We monitor the process parameters in real time through the intelligent production system, and have a number of national invention patents and utility model patented technologies. For example, the multilayer composite enameled wire for 5G communication solves the problem of coating adhesion and has a domestic market share of over 11.2%.
3. Q: Do the conductor materials meet high standards
A: We use annealed low-oxygen and oxygen-free copper wires, which are superior to ordinary copper in terms of oxidation resistance and conductivity, and have passed industry certification. For example, the purity of the conductor is 99.97%, which ensures low resistance and low heat generation in long-term use.
4. Q: How long is the lead time for order delivery
A: For stock, we can ship the goods to the port of loading within 7 working days after we receive the deposit. For production period, it usually takes about 15 days to 30 days to ship the goods to the port of loading after we receive the deposit.
5. Q: How to deal with quality problems
A Please keep the product samples and contact customer service.
6. Q: Why do I buy enameled wire with many pinholes in the salt water test
A: The national standard stipulates that the correct way to take samples for testing is that the specimen should not be subjected to tension or unnecessary bending when it is removed from the package. Before each test, enough enameled wire should be removed to ensure that the specimen does not contain damaged wire segments. Dry never bend yo!
7. Q: Why is the resistance tested, greater than the specified range
A: The national standard specifies the resistance test environment of 20 ℃, the southern region of the basic test time is more than 30 ℃ high temperature weather, and the general customer themselves do not have a constant temperature laboratory, so the test results will be high. Or according to the temperature index converted to 20 ℃ resistance.
8. Q: Why is there a color difference between the two batches of products
A: Enameled wire is the main pursuit of product performance, the color of small differences do not affect the quality, please rest assured that the use.
9. Q: During the use of fine wire, there will be many threads and can't find the threads
A: The stretching force of fine thread is relatively poor, easy to break the thread. Just need to hand all the thread together (can not find the thread of the surface of the thread pulled off some), the surface of the waste line slowly gathered, remove some waste line, and finally will become a thread. Finding the thread is to remove some of the waste line and rest assured boldly collect
