Abstract
Engineering solutions for the development of linear and connective sections of 110-kV current conductors with solid insulation are considered. Calculations of the electric-field strength in the presence and absence of insulation grading are performed showing the features of design solutions for linear sections. According to the calculations, grading reduces the range of the field-strength distribution by almost 150%. It is established for the 110-kV current conductors of this design that the optimal number of layers is eight. The admissible maximal field strength is estimated versus the dielectric strength of the insulation of the linear section of current conductors in the insulation thickness. The study results are used to establish that the maximum admissible field strength values are not exceeded.
