Abstract :
The main properties of ethylene propylene rubber (EPR) compounds for the insulation of high-voltage power cables are summarized in comparison with those of other solid dielectrics; the discharge resistance of EPR is emphasized. Construction and installation data, as well as electrical acceptance and qualification test results for four EPR-insulated cables rated from 20 to 60 kV are given; attention is drawn to the installation of a 45-kV cable, 800 meters long, directly buried in the ground, in service in an industrial plant since January 1965.
