Abstract :
A calculation method is presented for continuous rating of cable lines. The method takes into account 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 for a full-scale experimental installation were used to check the theoretical model. Comparison between the measured and calculated rises showed a difference of 5% in general and a maximum of 7%, which may be considered acceptable for line design
