UDTCF 155 Grade 0.1mm/400 Nylon silk served copper litz wire
The advantages of silk covered litz wire in electronic manufacturing are mainly reflected in its insulation performance and temperature resistance. Its insulating layer is made of enameled copper wire, which can prevent the wire from being scratched and short-circuited, and ensure the stable operation of electrical equipment. The outer layer is covered with nylon, which enhances the wear resistance and corrosion resistance of the wire, ensuring the safe operation of electrical equipment in harsh environments.
In addition, silk covered litz wire has good high temperature resistance, and the temperature resistance level can reach 155 degrees, which can be used in electronic assembly, motor manufacturing and other industries under high temperature environment.
