Abstract

To improve mean-life and reliability of power cable in this paper, we have investigated stress-strain and smoothness showing by changing the content of carbon black that is semiconductive additives for underground power transmission. Specimens were made of sheet form with the three of existing resins and the nine of specimens for measurement. Stress-strain of specimens was measured by TENSOMETER 2000. A speed of measurement was 200[mm/min], ranges of stress and strain were $400(Kgf/cm^2)$ and 600[%]. In addition tests of stress-strain were progressed by aging specimens at air oven. Finally we wished to look for protrusion of specimens by using smoothness tester. According to increasing the content of carbon black from this experimental result, yield stress was increased, while strain was decreased. And stress-strain were decreased some after aging because of oxidation reaction of chemical defect. Lastly surface of specimens smoothed generally.
