The present invention relates to a polyolefin resin composition having improved softness suitable for a power cable for power transmission and distribution. More particularly, the present invention relates to the polyolefin resin composition having excellent cold resistance, mechanical characteristics, and insulation characteristics, at the same time, having improved softness. The polyolefin resin composition can be used as an insulating layer material of the power cable without cross-linking, thereby being able to recycle. 본 발명은 송배전용 전력 케이블에 적합한 연질성이 개선된 폴리올레핀 수지 조성물에 관한 것이며, 보다 상세하게는 내한 특성, 기계적 특성 및 절연 특성이 우수함과 동시에 연질성이 개선된 폴리올레핀 수지 조성물에 관한 것으로서, 가교 없이 전선의 절연층 소재로서 사용될 수 있어서 재활용이 가능하다.
