| 摘要 |
The invention relates to a closed busbar system (10) for three-phase low voltage distribution, comprising phase bars (16 - 18) that extend lengthways and transverse branch bars (21 - 23), one of which is respectively electrically connected to an associated phase bar (16 - 18). The phase bars (16 - 18) are maintained in an inserted manner in a socket (27) of an insulating housing (12 -15) for reducing the cross-section or increasing the power in such a manner that a cooling channel (30) associated with each phase track (16 - 18) is formed between the rear side of the phase tracks (31) and the base inner side (32) of the socket (27). |
