An ultra-high voltage direct current (DS) power cable may be provided via a conductor formed by twisting a plurality of strands, an inner semiconducting layer surrounding the conductor, an insulating layer surrounding the inner semiconducting layer; and an outer semiconducting layer surrounding the insulating layer, wherein the insulating layer is formed of an insulation composition containing a polyolefin resin and a crosslinking agent, and the insulating layer is divided into three equal parts in a thickness direction, the three equal parts including an inner layer, an intermediate layer and an outer layer.

Ultra-high voltage direct current power cable

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.

Insulation composition having low dielectric constant, and cable including insulation layer formed therefrom
