Abstract

The authors conducted differential scanning calorimeter (DSC) measurements of various crosslinked polyethylenes of known thermal history, and found close relationships between the DSC profiles and the thermal history. From the detailed investigation of these relationships, the temperature and the period of heat treatment can be correlated into functions for the DSC profiles. Using these relationships, one can estimate the thermal history. Applying this method to actual cable, the results show good agreement with the thermal history of the cable. It is concluded that this method is useful and beneficial for revealing the thermal history on crosslinked polyethylene insulated cables and for considering the thermal behavior of the cable
