The article is devoted to the calculation of electromagnetic field strength (EMF) in theinsulating material a power cable (SC). magnetic single sample APvPu-101x240/70 was investigated. Theoretical information given for calculating ofan electrostatic axisymmetric based on solution Fredholm integral equations piecewise homogeneous linear polymer insulation with inclusions. Models are constructed...

Mould and process are developed for an injection molding rejuvenation technique of cable insulation failure. Disregard the traditional clue that repair does not expand original damage in size space, a new technique, i.e. molding, is restoring In this uncertain space was replaced by standard eliminated space. way, expanded with certain firstly made around failure section. But situation modified ...

To reduce the induction voltage in metal sheath, cross-bonded grounding is a widely adopted method long-distance high power cables, but this introduces challenges to online monitoring and diagnosis of cable insulation. An for insulation based on analysis resistive current proposed paper. A theoretical formula separation between leakage sheath was derived, obtained. equivalent circuit three-phas...
