摘要： The present invention 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.

摘要： Provided is a power cable, particularly, an ultra-high voltage underground or submarine cable for long-distance direct-current transmission. More specifically, the present invention relates to a power cable, in which an insulating layer has high dielectric strength, an electric field applied to the insulating layer is effectively reduced, and particularly, a large void is suppressed from occurring in the insulating layer when the power cable is left at low temperatures for a long time until electric current is supplied thereto after installed in a low-temperature environment, thereby effectively preventing partial discharge, dielectric breakdown, etc. from occurring due to an electric field concentrated in the large void.

摘要： The present invention relates to a power cable and, particularly, to an extra-high voltage underground or submarine cable. Particularly, the present invention relates to a power cable in which an insulation layer, itself, has high dielectric strength, an electric field to be applied to the insulation layer is effectively buffered, degradation of the insulation layer can be prevented during a cable connection step such that the life of the power cable is extended and simultaneously, the thickness of the insulation layer is minimized such that an outer diameter of the cable is reduced, thereby enabling flexibility, ease of installation, workability and the like of the cable to be improved.
