| Abstract: | The heat dissipation of electric power cable under different diameters,lengthsand materials of its shield tube is studied,the heat convection of the air layer betweena power cable and shield tube is the major part of this study.Both experiment andnumerical simulation are conducted to derive the correlation equations for average heattransfer within the applicable diameter range.The optimum diameter ratio and the relations of conductor temperature to shield tube length are given in this paper. |
| Keywords: | s:electric cable heat dissipation underground |
