COMPUTER ANALYSIS OF ELECTROMECHANICAL STRESS IN POLYETHYLENE INSULATION OF POWER
CABLE AT AVAILABLE MICRO-INCLUSION
.M. Kucheriava
Institute of Electrodynamics, National Academy of Sciences of Ukraine,
r. Peremogy, 56, Kyiv-57, 03680, Ukraine.
As applied to polymer insulation of extra-high voltage power cable, the distributions of volume electric force and con-
nected with the force mechanical stress in the zone of separate water microinclusion and inclusion with treeing channel
are studied. The qualitative patterns and quantitative estimations for the values of electric force and maximum von
Mises stress are obtained for microinclusions of different sizes. The mathematical model and computer program are
developed to determine electric force and mechanical stress in polyethylene taking into account structural defects filled
with water as well as to simulate the mechanism of destructive action on inhomogeneous insulating material. Refer-
ences 12, figures 5.
Key words: cross-linked polyethylene insulation, micro-sized inclusion, treeing channel, mechanical stress, von Mises
stress, computer modeling.
