| 摘要 |
The present invention relates to a transposition device for a prefabricated electrical canalization, said canalization includes a certain number of conducting bars distributing different phases including or not the neutral, the bars extending substantially parallel to one another, the transposition device being designed to reverse the position of at least two bars with respect to one another in the canalization. This device is characterized in that it is designed to be incorporated in said canalization, and includes the same number of portions of bar as the number of above-mentioned bars of the canalization, at least one of these portions of bar being interrupted inside the device so as to form two parts of portions of bars, these parts includes at their ends a fold towards the outside of said device thus forming an end part that is outwardly offset so as to increase the space between these end parts.
