| Summary: | Commercially available sag-tension programs give good results for most practical applications. However, they have some limitations concerning gap-type conductors. A separate aluminum and core creep calculation is needed due to the especial structure of gap-type conductors. For the same reason, different core and aluminum lengths have to be considered. In order to take into account the creep during the installation process, flexibility for the consideration of several stages is needed. A method that considers all these characteristics has been developed and implemented in a comprehensive, versatile and flexible sag-tension software tool, called STOC (Strain-Tension in Overhead Conductors). The program has been designed for the analysis of gap-type conductors. However, the method is a general method that can be used for any type of conductor, especially when flexibility for the calculation of several creep conditions is needed. |
