Square Compressed Film-Insulated Litz Wire is a high-frequency high-performance insulated wire. Adopting high-purity oxygen-free copper and precision square compression technology, it eliminates internal gaps of traditional round Litz wires. Featuring low high-frequency loss, high voltage resistance and high space utilization, it is ideal for miniaturized, high-power and high-isolation windings for new energy, medical, power and consumer electronic devices.
Round Litz wires produce large stacking voids and waste internal space. Our precision square compression structure achieves dense & high-fill winding, greatly improves slot utilization, reduces equipment overall size, and supports lightweight & miniaturized product design.
