Abstract

The present invention relates to a power cable and, particularly, to an ultra-high voltage power cable. Specifically, the present invention relates to a power cable, which is eco-friendly, has excellent heat resistance and mechanical strength, has an insulating layer made of an insulating material having excellent flexibility, bendability, impact resistance, cold resistance, installability, workability, and the like in a trade-off with the properties thereof, and, in particular, further improves the lifespan, workability due to flexibility and installability, and the like, through precise adjustment of the thickness of the insulating layer according to the characteristics of the insulating material.

Description

technical field [0001] The invention relates to a power cable, in particular to an extra-high voltage power cable with a voltage above 45kV and below 600kV. Specifically, the present invention relates to a power cable having an insulating layer composed of an insulating material that is environmentally friendly and excellent in heat resistance and mechanical strength while having a trade-off relationship with these physical properties (trade- off), excellent flexibility, bendability, impact resistance, cold resistance, laying and workability, etc., especially, the life of the cable is further improved by precisely adjusting the thickness of the insulating layer based on the characteristics of the insulating material, based on flexibility and Laying workability, etc. Background technique [0002] A typical power cable may comprise a conductor and an insulating layer surrounding said conductor, and in particular, in the case of a high voltage power cable or an extra high volt...
