description: This work is devoted to the study of thermal and electromagnetic fields in structural elements of cable lines with XLPE insulation, using the example of special low-inductance coaxial cable lines. The objectives of this work are: - Numerical finite element modeling of electric and thermal fields in XLPE insulation to assess the load capacity of the cable; - Accounting for actual laying conditions when calculating the temperature regime; - Selection of the optimal test voltage of ultra-low frequency (VLF) 0.1 Hz to check the quality of the insulation after installation and laying of cable lines. The objects of research are impulse cable lines and cable systems of medium voltage, mathematical models. The basis of research methods is the provisions of cable technology, the theoretical foundations of electrical engineering, high voltage technology, numerical methods for calculating electromagnetic fields.
