1980's SRP construction! I love these double-circuit composite line posts and even more on wooden poles. This pole is probably from about 1985. Also SRP used to have more lines with double-circuit wooden crossarms with suspensions but most of them are all gone. SRP switched to this type of armless construction in the mid-to-late 1960's, while still using crossarms for just slack span unfortunately until about the 1980's.

Some older mid-1980's double-circuit composite line post poles in the background. In the foreground, you've got the steel double-circuit polymer yuk posts. I never cared for those polymer post steel poles. Many lines of them now plague lines that once featured pre-1966 older crossarms poles with suspensions or composite line post poles. New 69kV poles are completely steel now as of the late 1990's-early 2000's. Polymer posts have been a standard since between 1994-97.
