This is a section of Entergy's Sterlington, LA 115kV substation. It was built in 1924-25. Look at the copper tube bus! The insulators are original too. They are 4 part post insulators. They are Ohio Brass and Locke insulators....identical to M-4611, but with a metal cap and base. Here's a close up picture of a Locke 4-part taken from a sister substation built the same year.
