HEAT TESTS OF POWER CABLES WITH XLPE INSULATION AT DIRECT VOLTAGES UP TO 110 KV

In this paper, experiment for determining the temperature difference between the elements of cable and in the open air is considered. The formation of a three cables laid in a plane with different spacing between adjacent cables. Tests to heat of cables for XLPE-polyethylene are used as a solid diel...
