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 a power cable, and particularly, to an ultra-high-voltage power cable of 45 kV to 600 kV. Specifically, the present invention relates to a power cable which is eco-friendly and includes an insulating layer formed of an insulating material having not only high heat resistance and mechanical strength but also high flexibility, bendability, impact resistance, cold resistance, installability, workability, etc., which are in trade-off with heat resistance and mechanical strength, and of which the lifespan, flexibility and installability can be additionally improved through precise control of a thickness of the insulating layer according to characteristics of the insulating material, thereby enhancing workability.
