The HUAERDA Manufacturer Sales Class 155 0.670mm Solid Copper Polyester Enameled Wire is a high-quality electrical wire designed to meet the needs of power adapters and other electrical applications. This wire is made from solid copper, which ensures excellent electrical conductivity and durability. The copper used in this product is solid, meaning it offers consistent performance and strength compared to stranded wires.
One of the key features of this wire is its polyester enamel coating. This enamel acts as an insulating layer, allowing the wire to handle high voltages safely — up to 4800 volts. The polyester insulation also provides good resistance to heat, making it suitable for use in environments where temperatures can be quite high. This makes the HUAERDA enameled wire ideal for power adapters, transformers, motors, and other electronic devices that require reliable electrical connections.
With a diameter of 0.670mm, this wire strikes a good balance between strength and flexibility. It is thick enough to carry significant electrical current without overheating, yet still flexible enough to be easily bent and shaped during assembly or installation. This makes it user-friendly for manufacturers and technicians alike, as it can be used in a variety of designs and setups.
The wire’s Class 155 rating means it can withstand continuous operation at temperatures up to 155 degrees Celsius without degrading. This ensures long-lasting performance in demanding conditions, reducing the risk of failure and the need for frequent replacements. Additionally, the high voltage rating of 4800V makes the HUAERDA wire a safe choice for electrical equipment that operates at higher voltages, offering peace of mind for users concerned with safety and reliability.
HUAERDA is known for producing reliable and high-efficiency electrical components, and this polyester enameled copper wire is no exception. It is manufactured with strict quality control measures to ensure each spool meets rigorous industry standards. Whether you are building power adapters, repairing electrical devices, or working on new electronic designs, this wire delivers consistent performance and safety.
The HUAERDA Manufacturer Sales Class 155 0.670mm Solid Copper Polyester Enameled Wire is a durable, heat-resistant, and high-efficiency wire ideal for high-voltage electrical applications. Its solid copper core, polyester insulation, and quality construction make it an excellent choice for power adapters and many other electrical needs. Choose HUAERDA for wire that performs well under pressure and stands the test of time

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.
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, rest assured to boldly collect it.
