Single-core copper magnet wire is a type of wire with a single copper conductor as its core and an insulating paint film coated on its surface. It is widely used in the manufacturing of windings for motors, transformers, inductors, relays, and other electromagnetic devices, and complies with NEMA MW-1000.
Thermal Properties
Single-core copper magnet wire remains stable in a high-temperature environment of 150℃±3℃ while withstanding 30% tensile stress. Its insulation layer can endure the dual effects of mechanical stretching and high temperature, effectively preventing insulation failure caused by thermal expansion and contraction or external pulling forces in scenarios involving abrupt temperature changes or existing assembly stress, thus ensuring the long-term electrical safety of winding equipment.
Chemical Properties
When single-core copper magnet wire is immersed in xylene solution, its coating does not soften or peel off, remaining tightly wrapped around the conductor at all times and eliminating the risk of copper wire exposure. This characteristic ensures that in industrial environments in contact with organic solvents, its insulation performance is not eroded; it can stably resist the impact of chemical media, thereby extending the service life of the equipment.
Mechanical Properties
The conductor of single-core copper magnet wire is made of high-purity copper, which has excellent ductility and tensile strength, enabling it to withstand moderate tensile force during the winding process without easily breaking. Meanwhile, the insulating paint film adheres tightly to the copper core; within a reasonable stretching range, there will be no peeling or cracking of the paint film. This ensures that the conductor and the insulation layer bear force synchronously, preventing performance failure caused by mechanical damage.
Electrical Properties
The high-purity copper conductor features excellent electrical conductivity and low power transmission loss, making it suitable for the efficient operation of equipment such as motors and transformers. The insulating paint film boasts high insulation resistance and strong breakdown voltage, which can effectively isolate interturn current and prevent short circuits. With low dielectric loss and good arc resistance at high frequencies, it is suitable for high-frequency circuits, comprehensively ensuring the stability and safety of the equipment.
