Features
Square Cross-Section: Unlike round wire, this wire has a square cross-section, which allows for better space utilization.
Enamel Insulation: Coated with an enamel layer that provides electrical insulation and protects against environmental factors.
High Conductivity: Made from copper, ensuring excellent electrical conductivity.
Heat Resistance: The enamel coating is capable of withstanding high temperatures, making it suitable for demanding applications.
Mechanical Strength: The square shape offers greater mechanical stability and resistance to deformation.
Benefits
Space Efficiency: The square cross-section allows for tighter packing of windings, leading to a more compact design.
Improved Heat Dissipation: Larger surface area relative to volume enhances heat dissipation, which is critical in high-power applications.
Higher Fill Factor: The square shape reduces the gaps between wires in the winding, increasing the fill factor and thereby improving the overall efficiency of the device.
Enhanced Mechanical Stability: Provides better mechanical stability under stress compared to round wires.
