| Abstract: | A numerical simulated model for temperature distribution in 3-phase power cable is set up in this paper according to the structural parameters and thermal stable characters of cable in service. The internal thermal field of XLPE cable is calculated by using Controlling Volume Integral Method. The thermal thermograms of typical cross-section of cable can be drawn accurately with the use of the developed simulation software. The research results are useful for the design of insulation structural and diagnosis of thermal failure of XLPE cable. |
