Advantages
While some concerns have arisen among OEMs/Tier 1s regarding wrapped flat wires, it is important to highlight that this solution offers a number of unique advantages. Thanks to the use of a specific glue during the taping process, we guarantee a strong adhesion to the conductor, allowing the creation of complex configurations such as the hairpin-type bend. This aspect, often a source of concern, is successfully overcome, offering a highly flexible and adaptable solution to project needs.
Furthermore, the Polyimide-FEP wrapped flat wire has one of the highest resistances to partial discharges on the market, comparable to solutions such as PEEK. This attribute, combined with excellent oil compatibility, positions it as an ideal choice for applications where safety and performance are priorities.
De Angeli Prodotti continues to challenge conventions, offering innovative and reliable solutions in the field of E-Mobility. Polyimide-FEP wrapped flat wires represent a step forward, guaranteeing flexibility, safety and high level performance in a constantly evolving sector.
