CALCULATION OF THE HEATING TEMPERATURE OF CABLE INSULATION WITH THE JOINT STRIP
The article is devoted to the level of insulation of the cable lines - one of the main factors determining its condition. It is shown thatit dependsnot only on the level of the current flowing through the cable, but also on the presence of higher harmonics of the current, as well as on the number of cables laid side by side in one trench. The proposed method allowsto take into account the thermal influence of cables laid in one trench in calculating their temperature.
