Low-voltage power distribution cabinet busbar

The utility model discloses a low-voltage power distribution cabinet busbar, which comprises a first branch busbar connected with an incoming cable of a low-voltage power distribution cabinet and used for shunting incoming current provided by the incoming cable to obtain first branch current; and the second branch busbar is connected with the first branch busbar and is used for shunting the incoming current so as to obtain a second branch current. According to the utility model, the distribution of the incoming electric energy of the incoming line side of the low-voltage power distribution cabinet is realized, and the second branch current can be input to the second electric equipment (such as an original charging pile junction box) through the second branch busbar. And the first branch current is input to the first electric equipment (such as a newly added charging pile junction box) through the second conductor section of the first branch busbar, so that the electricity demand of the charging piles of which
