Cable Replacement

Roseville Electric has had several cable failures in the past year, dropping our service reliability severely.  After doing extensive analysis on the failed cable, we have found that these 12-kV bare-concentric cables, and those that have not yet failed, have reached the end of their operational life of 20 years. 

This project is to begin a cable replacement program to replace all mainline bare-concentric 12-kV cables that are 20 years and older.  This is an on going project until the year 2020 where all mainline bare-concentric 12-kV cables are replaced. Roseville Electric started to install jacketed XLPE tree-retardant or EPR 12-kV cables since 1998. These jacketed cables are expected to have an operational life of 40 plus years.
