That white box you show in this picture Is an amplifier for cable tv.

lol ooooh

usually on a Utility pole setup, The phone lines are the lowest lines on the pole, Then Cable TV are above them. Some setups may Differ though.

so where does the concrete poll wires come from a near by power plant i always was curious about that

A Power plnat will Produce Electricity To The Main Transmission Lines which are the High towers you see around. They then Feed A Substation which Go through a Stepdown Transformer, Typically 115kv to 13.8 kv which is most Distribution Primary voltage. You then Leave the substation feeding the distribuiton Lines to area business and homes which are again stepped down on the Gray, or sometimes Black transformers you see on the Utility pole which makes your normal Household Voltage of 120/240 volts. The concrete light poles could be feed from a near by pole of pad mount transformer, but not knowing your area its hard to tell.

yea my dad told me most of that stuff about the transformers like how they take high voltage down to the right amount for a home, and when i see them installing concrete and metal polls the wires come up threw the ground so im thinking that the wires that are on wood polls that fall to the ground that has the yellow tube on them has something to do with that but idk

usually the wire that go down the wood poles against the wood poles are the ones that goes to the streetlights...so the white tube that is against the wooden poles would be for the electrical to streetlights, or even to houses or anything that gets power from wires underground......usually the ones that goes down against the wooden poles are the low voltage power... (from transformer on wooden poles)

I remember one of my lineman friend was fixing a row of streetlights on fiberglass poles that had underground wiring which was controlled by an OLD photocell relay...GUESS WHERE the relay was? ON TOP OF A NEARBY POWERLINE POLE!!!!!!

wow and viberglass poll??? and imma take a pic of the line i was talking about with the yellow tube well actually i have one on my game that i can show you guys.....look out for it

Why are there two voltages for transmission lines? Like there are the 345 KV lines then the 115 KV lines, I wonder why they have two main voltages. And when I look at a power plant the power lines coming from it are both sets of voltages. Are the 345 ones supposed to go very far from power plant to power plant? Then the power stations that connect to the 345 downgrade it to 115 KV? And the 115 KV are supposed to go LONG distances but feed to primary lines?

That's my guess, but I could be wrong.

@ jace, the white tube on the lower left corner in this photo is for cable TV. You can see the coax wire coming directly from the white amp box on the trunk line. Now from a different photo of this pole, the rusted up RMC had a underground primary in it so that could be the feed to a padmount transformer which could be feeding homes and the area concrete poles.

@ Ian, there are more than just 2 transmission voltages, I've seen 69kv, 115kv, 138kv, 230kv, 345kv, 500kv, and even voltages over 700kv. Alot of it does depend in distance, but also the population of the area to.

I didn't notice the white one until you pointed it out......but I know Powerline wires that goes through against wooden pole tends to be covered with some kind of grey cover that covers over wires........

Yes sir, I've used this grey wrap guard call "U Guard" and we have even sleeved it it PVC.

Well the two main Transmission voltages here are usually 115 KV and 345 KV. That's all I have seen around here.

69 KV is sub-transmission lines, What voltages are for Primary, Sub-transmission, then transmission?
