156 Strands 0.32mm PI Taped Litz Wire with 6000V Breakdown Voltage for High-Frequency Efficiency
Efficiency is the heartbeat of innovation in the New Energy Vehicle sector. To maximize driving range and minimize energy dissipation, every component in the power electronics chain must be optimized. Our 0.32mm * 156 strands PI Taped Litz Wire is designed specifically to enhance the efficiency of high-frequency power conversion. In modern EV inverters and converters, operating frequencies are constantly increasing to reduce component size. However, at these high frequencies, standard solid conductors suffer from massive power loss due to the skin effect, where current only flows on the surface. Our 156-strand architecture solves this by redistributing the current across a vast total surface area provided by the fine filaments, drastically reducing AC resistance and heat generation.
Encapsulated in high-performance Polyimide (PI) film, this Litz wire maintains its superior electrical properties across an incredibly wide temperature spectrum, from extreme cold to intense heat. The PI taping process ensures a precise and uniform insulation layer that supports a minimum voltage resistance of 6000V. This allows for more compact transformer and inductor designs, as the high insulation rating reduces the need for additional spacing or bulky potting compounds. Whether it is implemented in On-Board Chargers (OBC), DC-DC converters, or wireless charging systems, this Litz wire provides the high-frequency efficiency required to push the boundaries of EV charging speeds and overall vehicle performance. By reducing thermal waste, it also contributes to the longevity of the surrounding electronic components.
