Our Huaying Twisted Litz Wire offers a wide range of options. The finest available diameter is 0.10mm, capable of twisting strands from 50 to 2000 strands. The even thinner 0.05mm diameter allows for twisting strands from 50 to 3000 strands. Regardless of the customer's specific needs, we can meet these requirements. The finished product's outer diameter is also flexible, ranging from 0.1mm to 8mm. If customers have specific requirements for width or thickness, such as requiring a thinner gauge for installation in small medical devices, we can accommodate these requirements. We have also carefully researched our dielectric strength, demonstrating that our products exhibit no insulation breakdown even in high-frequency and high-voltage environments, earning them the trust of our customers.
This Huaying Twisted Litz Wire boasts a high slot fill rate, allowing coils wound with it to carry higher currents without overheating, even under high-current loads. Furthermore, it utilizes square stranded wire. For the same cross-sectional area, square wire has a larger surface area than round wire, which mitigates the skin effect, significantly reducing high-frequency current losses and improving heat dissipation. This ensures stable operating temperatures in automotive electronic devices over extended periods. Furthermore, our product's compact footprint makes it particularly suitable for applications requiring minimal size, such as optical storage. Furthermore, its temperature and radiation resistance reach 220°C, making it suitable for use in high-temperature industrial environments. This radiation resistance also ensures stable operation in specialized medical equipment, resulting in a wide range of applications.
Daily maintenance of the Huaying Twisted Litz Wire is straightforward; simply pay attention to a few small details. When storing, remember to keep the wires in a dry, well-ventilated area away from oil, dirt, and corrosive liquids. If you plan to store them for an extended period, it's recommended to wrap the wires tightly in a sealed bag to prevent moisture from entering. This is especially true during the rainy season in southern China, when the air is humid and can easily damage the wire's performance. If you need to cut the wires, be sure to use dedicated wire cutters. Don't use ordinary scissors to cut them. Otherwise, the twisted wire strands will easily break apart, causing problems when connecting them later. Also, when stripping the insulation, be careful not to break the copper wire. It's recommended to use a dedicated wire stripping tool and follow the equipment's requirements; don't strip too long or too short.
