Abstract :
The authors describe the results of an accelerated water treeing test after a period of approximately one year with two recently manufactured (1988) varieties of commercial EPR (ethylene-propylene rubber) cables, produced by different manufacturers and possessing different cable structures, as well as water impervious XLPE cable for comparison. In the test, bow-tie trees were found in the EPR insulation, which had previously been thought to develop no or few bow-tie trees. The analysis results of bow-tie in EPR cables are described
