litztråd
Litztråd, also known as litz wire, is a special type of wire used primarily in applications involving alternating current (AC) and high-frequency signals. It consists of multiple thin, insulated strands of wire carefully twisted or braided together to form a single conductor. The main purpose of litztråd is to reduce parasitic effects such as skin effect and proximity effect, which can cause increased resistance and energy loss in conductors carrying AC or high-frequency currents.
The skin effect causes alternating current to concentrate near the surface of a solid conductor, effectively
Litztråd is commonly employed in induction coils, transformers, radio frequency (RF) inductors, and other electronic components
Manufacturing litztråd involves precise insulated strand production, typically using materials like polyester, enamel, or polymer coatings.
Overall, litztråd exemplifies biomimicry of natural systems, where the structure is optimized to manage energy flow
