This work is devoted to the study of the design of power electric cable with impregnated paper-plastic insulation and its electrophysical properties. The tasks that were solved during the research:Study of material on the topic of the diploma work.Consideration of the main structural elements and materials of the power cable with paper-plastic insulation and their purpose. Conducting an experiment in a drying cabinet to measure the conductivity. Processing and analysis of obtained data, drawing conclusions from the results. Experimental work was carried out in the research laboratory of SPbPU: to measure conductivity of samples an installation consisting of a two-electrode cell, insulated cabinet and A2-4 picoamperometer was used. As a result of the performed work current and temperature dependences were obtained, electrophysical properties of cables with paper-plastic insulation were investigated on the basis of the existing model and advantages of its use in the modern world were revealed.
