Abstract
XLPE is widely used as a main insulation in EHV power cables, deeply connected with thermal stress. In this study, the thermal history of XLPE insulation was examined using DSC(Differential Scanning Calorimetry). The principle is on the basis of the phenomenon that crystal in polyethylene is rearranged as it is annealed near/below the melting temperature. From the result, it was possible to define accurate temperature which was really applied on the XLPE insulation and this method was assured as a useful tool in characterization of thermal history in XLPE cable insulation.
