제목 A Study on PTC/NTC and Mechanical Properties of Vinyl Polymer/Carbon Black Composite for Power Cable
초록 To improve mean-life and reliability of power cable, we have investigated volume resistivity and mechanical properties of vinyl polymer/CB composites, semiconductive materials for power cable. Specimens were made of sheet form with the nine of specimens for measurement. Volume resistivity of specimens was measured by volume resistivity meter after 10minutes in the preheated oven of both 25±1℃ and 90±1℃. And stress-strain of specimens was measured by TENSOMETER 2000. A speed of measurement was 200mm/min, ranges of stress and strain were 400Kgf/Cm and 600%. In addition tests of stress-strain were progressed by aging specimens in air oven. From experimental results of Figure 1 and 2, volume resistivity was high according to an increase of the content of carbon black. And yield stress was increased, while strain was decreased according to increasing the content of carbon black. And stress-strain were decreased some after aging because of oxidation reaction of chemical defect. We could know EEA was excellent more than other specimens from above experimental results2, 3.
