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.
