Advantages: Litz wire is constructed by twisting individually insulated thin wires in specific patterns, which significantly reduces AC losses in high-frequency applications due to its ability to mitigate skin and proximity effects. This leads to increased efficiency, lower operating temperatures, reduced footprint, substantial weight reduction, and avoidance of "hot spots" in transformers and inductors . Disadvantages:The manufacturing process of Litz wire can be complex and labor-intensive, leading to higher costs compared to solid wires. Additionally, the effectiveness of Litz wire begins to drop off above 3 MHz, and the packing factor or copper density can be affected by the enamel layer and inherent air gaps from twisting round wires together . Application Fields:Litz wire is widely used in various applications that require high-frequency operation and efficiency, such as stator windings, power transformers, motor generators, hybrid transportation, renewable energy systems, communication equipment, and medical devices. It is also utilized in induction heating applications, sonar equipment, and radio transmitter equipment, among others .
