  • Insulation composition for DC power cable and DC power cable prepared by using the same
    Patent number: 9183969
    Abstract: The present invention relates to an insulation composition for a DC power cable and the DC power cable prepared using the same. Specifically, the present invention relates to an improved insulation composition for a DC power cable, which can prevent decrease of DC dielectric strength and decrease of impulse strength caused by accumulation of space charges, and the DC power cable prepared using the same.

  • DC power cable with space charge reducing effect
    Patent number: 9076566
    Abstract: Provided is a DC power cable including a conductor, an inner semiconductive layer, an insulation and an outer semiconductive layer. In particular, the inner semiconductive layer or the outer semiconductive layer may be formed from a semiconductive composition containing a polypropylene base resin or a low-density polyethylene base resin and carbon nano tubes; and the insulation may be formed from an insulation composition containing a polypropylene base resin or a low-density polyethylene base resin and inorganic nano particles. The resulting power cable may have improved properties such as volume resistivity, hot set, and so on, and excellent space charge reducing effect.
