PEEK wire can be stabilized at high voltages due to their excellent electrical properties. The specific high voltage resistance varies depending on the diameter of the cable and the thickness of the insulation.
With the rapid development of new energy electric vehicle technology, 800V or 1200V drive systems are becoming the focus of attention for major manufacturers. one of the key challenges for 800V motors is the stability of flat winding wires at high voltages.
PEEK extruded flat wire is not only a simpler production process, but also a more stable product. It does not require multiple coats and baking to achieve excellent pressure resistance. In addition, the flat wire is able to withstand repeated bending without breaking when processing hairpins.
With many years of experience in the development and production of motor magnet wire, the BW material company, through the tireless efforts of its R&D and technical teams, has succeeded in developing PEEK insulated wires with high-temperature resistance, high flame retardancy, power up high-voltage mobility, radiation resistance, and excellent mechanical properties.
