要約(日本語): In this work, the recyclable new modified polyethylene (PE) and polypropylene (PP), which are thermoplastic, have been investigated as the eco-friendly insulating candidates to replace the cross-linked PE (XLPE).The temperature dependence of conductivities of these materials has been measured for 1 hour in the range of 30°C ~ 90°C for each test units, and its effects on the electrical field and space charge distributions in DC polymeric insulated power cable under temperature gradient have been calculated.It is shown that the sensitivity of conductivity to temperature change has more critical influence to determine the electrical field distribution in power cable than the absolute value of conductivity does and it can be said that the temperature dependence is one of the most important factor for DC power cable development and design.
