초록

In this paper, to obtain the material properties through the semiconducting shields of 22kV XLPE power cable. the water absorption TGA DSC and dielectric properties were respectively measured between semiconducting shield and XLPE. Especially, dielectric properties were measured with temperature variation. Above result, the water absorption was 1200 ppm and the ratio of carbon black was 40% in semiconducting shields. The dielectric constant was $10^3{\sim}10^5$, $tan{\delta}$ was $10^2{\sim}10^3{\Omega}cm$ and volume resistivity was $280{\sim}2.8{\times}10^3$.
