Abstract: Provided is a high-voltage power cable. Specifically, the present disclosure relates to a high-voltage power cable that exhibits excellent dielectric strength, such as dielectric breakdown voltage and impulse breakdown strength, and that is capable of implementing and maintaining dielectric characteristics even when a temperature of a cable insulator rises due to the transmission of power or when negative impulse or polarity reversal occurs.

Abstract: Provided is an insulator that is environmentally friendly and has high heat resistance and mechanical strength and excellent flexibility, bendability, impact resistance, cold resistance, installability, workability, etc., which are in a trade-off relationship with the physical properties; and a power cable having the insulator.
