Wires, single and multi-insulated with modified ETFE, class F

€0,00

Due to their dielectric strength, multi-insulated wires with fluoroplastics allow the construction of compact transformers without intermediate insulation between the primary and secondary windings. This results in better magnetic coupling between the windings, which results in lower leakage inductances.
