【 摘 要 】

The work is devoted to study of temperature operation of a 150 kV underground cable line with XLPE insulation. The stationary thermal conditions were calculated. The influence of outer boundary radius selection on the temperature distribution was analyzed. The limiting value of the filling mixture thermal conductivity was found, which provides an acceptable temperature of the cable.
