Multistress endurance characterization of EPR cable models

The results of life tests performed on EPR cable models aged by combined thermal-electrical stresses are reported, showing electrical and thermal life lines, intersections of the life surface with the planes at constant stress. The Combined Analysis Method (CAM) is used to obtain more information on the behavior of the tested cable in a wide voltage and temperature range. Parameters useful for insulation characterization and cable design are derived.<>
