BUS DUCT REDUCING VIBRATION AND NOISE

摘要

Disclosed are a bus duct for reducing vibration and noise by using a hybrid -type external case. A bus duct according to an embodiment includes an 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. A current flows along the bus bar. The non-magnetic part of the external case can generate a force due to an eddy current and a magnetic field compared to the magnetic part of the external case when a current flows through the bus bar.
