It is one of the most important that the cable ampacity correctly under transient conditions is defined to guarantee the safe operation of cable. In this paper, the calculation of cable ampacity is based on the method provided by IEC60287 and IEC60853 standard. An ampacity calculation program for screened 10kV XLPE cables, based on the thermal circuit technique, is developed in MATLAB language. By...
Due to the increase of power load in the central area of big cities, the application of power cables are quickly increased. Compared with other laying methods, pipeline shows some significant advantages, and also some disadvantages such as the difficulty of obtaining its temperature distribution and setting its suitable ampacity. On the basis of FEM model of temperature field of 10kV underground pipe-laid...
