Serving
High frequency litz wire served with natural silk, polyester or nylon is characterized by an increase in mechanical performance and excellent dimensional stability. The precise serving quality guarantees a high degree of flexibility and prevents splicing during the process of cutting the litz wire and therefore allows for optimal contacting.
