Enameled round copper wire is a type of magnet wire, featuring a round copper core with an outer insulating enamel coating. This structure endows it with excellent wire winding flexibility and a high slot fill factor, meeting the needs of various electrical applications.
Enameled Round Copper Wire Features
High-quality conductor material: High-purity oxygen-free copper rods are used and processed into circular cross-section conductors through multiple drawing passes and precision annealing processes, featuring low resistance characteristics under high current density.
Insulation performance: It has excellent insulating properties; the insulation layer is resistant to peeling and can effectively prevent short circuits.
Excellent flexibility: It can withstand 180° bending for 3 times without paint film cracking. The elongation of 0.050 mm conductor is ≥14%, and that of 0.320 mm conductor is ≥29%. The rebound angle is ≤30°, ensuring tight fit with the slot during winding and improving the slot fill rate.
Corrosion resistance: The enameled round copper wire has a stable coating material with tight wrapping, so it can be used for a long time in humid, oily, and even mildly acidic or alkaline environments without being easily corroded
Applications:
motors: Enameled round copper wire has good flexibility, and its circular cross-section allows for tight arrangement. This enables more turns to be wound within the limited motor housing, thereby improving the motor’s power density.
Transformers: Enameled round copper wire has low conductive loss, and its insulation layer is voltage-resistant, making it suitable for transformers.
Various electronic components, such as inductance coils and relays: These components require wires to have a small diameter, a thin insulation layer, and the ability to work at high frequencies, making enameled round copper wire highly suitable.
