Here is the new equipment the power co. installed on the pole on the corner. This pole had a large transformer on it that stepped down the voltage from 34,500 volts to 4,160 volts for the neighborhood and now it has an underground termination to overhead directly to the 34 kv line with a lighting and surge arrestor. This pole is also sporting an AEL 115 70 watt HPS on a Shakespeare 12 foot tapered elliptical bracket.
That's interesting...I thought the higher voltages had larger insulators. The ones here are the size I see typically used for 4,160v lines going through the residential areas.
This more looks like a 25kv insulator since 34kv to ground is roughly 21kv and this only being single phase. There should be a nameplate on the new padmount telling you the primary voltage of the transformer.
Yes it's actually 19,200 volts phase to ground. But we do have a 34 kv system on the overhead phase to phase. These insulators I call pin insulators do the same job as stack insulators with the rings just a different style.
