156 Strands 0.32mm Diameter PI Taped Litz Wire with 6000V Breakdown Voltage for High Frequency EV Systems
Precision engineering and material science converge in our 0.32mm * 156 strands PI Taped Litz Wire. This product is the result of rigorous manufacturing tolerances designed to provide the perfect balance between conductor surface area, flexibility, and insulation thickness. Each of the 156 individual strands is meticulously twisted in a specific lay pattern to ensure that each strand occupies the same average position across the cross-section of the wire. This precision ensures perfectly balanced current distribution and eliminates internal circulating currents. The outer Polyimide (PI) film is applied using advanced wrapping machinery that ensures consistent tension and a specific overlap percentage, guaranteeing a minimum dielectric strength of 6000V without adding excessive bulk.
The choice of a 0.32mm single wire diameter is a calculated decision, making this specific configuration highly effective for the medium-to-high frequency ranges (typically 10kHz to 100kHz) common in NEV power electronics. The PI tape insulation acts as a multi-functional shield; it is not only a high-voltage barrier but also a thermal protector and a mechanical guard against the stresses of high-speed automated winding. We understand that in the automotive supply chain, consistency is key. Therefore, our PI Taped Litz wire is manufactured to ensure uniform outer diameters and stable electrical characteristics from the first meter to the last. By integrating this wire into your designs, you are choosing a component that combines high-strand-count electrical efficiency with the industry's most durable and heat-resistant film insulation technology.
