  • ULTRA-HIGH VOLTAGE DIRECT CURRENT POWER CABLE
    Publication number: 20230377768
    Abstract: Provided is an ultra-high-voltage direct-current (DC) power cable. Specifically, the present invention relates to an ultra-high-voltage DC power cable capable of simultaneously preventing or minimizing electric field distortion, a decrease in DC dielectric strength, and a decrease in impulse breakdown strength due to accumulation of space charge in an insulator.
