摘要

Disclosed is a bus duct for reducing eddy current loss by using a hybrid-type external case. The bus duct according to an embodiment may include: the external case of which at least one part is made of a non-magnetic material and other parts are made of a magnetic material; and a bus bar which is received in the external case.
