Electrical-breakdown characteristics and testing of high-voltage XLPE- and EPR-insulated cables

Technical Report ·
OSTI ID:7096144

Threshold voltages and other basic breakdown characteristics, spanning times from microseconds to cable life expectancy, were determined for cross-linked polyethylene (XLPE) and ethylene propylene rubber (EPR) cables. These results are based upon measurements of 60Hz, high frequency, impulse, and impulse with dc bias voltages. Based on the breakdown characteristics an improved, procedure for the factory testing of full-reels of polymeric insulated cables and for 2 year qualification testing of XLPE cables is proposed. This procedure can help assure proper performance of cables throughout their service life.
