"Stand-off" insulator brackets with 15kV-rated brown insulators. Common throughout the late 1960's until mid-1970's. The street light is a ITT Model 25 FCO from the early-mid 1980's.

Same pole as in the previous photo. 1980's SRP. N 91st Ave. Source: Google Maps

1980's SRP with a cap bank. Mostly unmolested since when the pole was installed, which I'd estimate was between 1980-85. Source: Google Maps

1980's SRP. This riser is usually used for smaller residential/commercial developments. Source: Google Maps

A General Electric M400A1 full-cutoff HPS model used throughout the 1980's-90's all around Phoenix. Much of these have since been replaced by the rather generic GE M400A3 Full-Cutoff that have popped all over the place (which UI in Connecticut replaced about 99% of their streetlights with a few years ago). I've always liked this GE model. :) Source: Google Maps

1980's SRP. SRP used these less sophisticated risers often between 1967-95. Source: Google Maps

1980's SRP. These distribution KPF armless switches were used throughout the 1970's-80's. Source: Google Maps

1980's SRP. The distribution line below was a common deadend in the 1970's-80's which utilized a "triangular" configuration. SRP rarely use these constructions on new deadend poles, which currently are brace-clamped 6' or 8' wooden crossarms or vertical assembly using polymer strains. Source: Google Maps

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.
