摘要： 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.

摘要： Provided is an insulation composition having a low dielectric constant and a cable including an insulation layer formed of the insulation composition. More particularly, the present invention relates to an insulation composition for reducing a space charge to increase superimposed impulse breakdown strength when impulse voltages overlap during application of a direct-current(DC) voltage, having a low dielectric constant, and improving impulse breakdown strength, and a cable including an insulation layer formed of the insulation composition.
