Service Life Estimation Technique of Oxidized XLPE Cables

Abstract

XLPE which is the insulator of the XLPE cable will be oxidized by heat. But, an accident caused by oxidized XLPE has hardly reported until now. Therefore, oxidization of XLPE hasn’t been regard as important. But recently we found that XLPE cable used for a long time could break down due to the oxidization of XLPE by simulation result. So, we developed the service life estimation technique of oxidized XLPE cables used FT-IR.
