Abstract

The invention concerns a connecting means (3, 6, 7, 8) comprised of cables and/or other known types of conductors between a frequency converter (1) and its load (2), the latter being a motor or another electric apparatus. According to the invention the connecting means is constituted by two or more parts connected in series such that at least at one point the two successive parts (6, 7, 8) show different wave impedances.
