Old substation transforming 23kv to a lower voltage (most likely 480v) to power Beacon Feeds in Eastport, NY. Note the Frankenstein style switch and the tall, oddball arrestors. The transformers were made by a company in New Hampshire. Replaced by a 13kv padmount when LILCO (now Long Island Power Authority) bought PELCO and the 23kv network got downsized.
