This paper presents a calculation method for current continuous rating of cable lines that considers the actual environment conditions, such as different types of soil, change of geometrical disposition, etc... This method is based on the resolution in terms of limit differences. The results of a full scale experimental installation, were used to check the theoretical model precision. The comparison between the measured and calculated rise show a difference of 5% in general and a maximum of 7% which may be considered acceptable for line design.
