Abstract
The present disclosure relates to a power cable system capable of determining the possibility of brittle fracturing of a different conductor connecting part of power cables due to tensile force applied to the different conductor connecting part, the power cable system comprising: a first conductor constituting a first power cable; a second conductor constituting a second power cable; and the different conductor connecting part formed by bonding the first conductor and the second conductor by means of resistance welding, wherein the average thickness of an intermetallic compound layer formed on the bonding surface of the different conductor connecting part is 10 μm or less, which is the critical average thickness at which a brittle fracture occurs during a tensile test.
