Numerical Simulation on the Temperature Distribution by Ventilation Type during Heat of the Power line in Electric Power Tunnel

Power line in electric power tunnel generate heat around during power transmission. Rising temperature inside the electric power tunnel reduces the transmission efficiency of the power line. In this study, trying to understand the change in temperature in the electric power tunnel by forced ventilation and natural ventilation when the temperature rise of the electric power tunnel. The results show that average temperature in electric power tunnel by natural ventilation, forced ventilation is $56.55^{\circ}C$, $23.25^{\circ}C$. Therefore electric power tunnel during power transmission needs cooling or ventilation system.
