Responding to the demand for wireless power transmission! SQLW square cross-section litz wire.

Robots and medical devices can also be used! Increased filling rate of twisted wires improves heat dissipation due to increased cross-sectional area! Maintains equivalent performance to round shapes while contributing to miniaturization!

Currently, energy storage technology is rapidly advancing, and technological innovations are still being pursued. At the same time, there is a growing expectation and demand for wireless (non-contact) power supply technology. In various fields such as electric vehicles, which are expected to grow into a significant market, as well as robotics, drones, home appliances, and medical devices, the characteristics of SQLW square cross-section litz wire can be utilized. Compared to conventional round litz wire, using square or rectangular shapes can eliminate unnecessary gaps and increase the filling ratio of stranded wire by about 20%. Additionally, the resistance can be reduced by approximately 10-20%, and since a larger cross-sectional area can be achieved, heat dissipation through surface contact is improved, allowing for a higher current flow. It is also possible to increase the number of turns while maintaining the same external dimensions as the previous round litz wire, making it suitable for the rapidly increasing demand for wireless fast charging, while also contributing to miniaturization without compromising performance.
