refinery power lines

[STLmo1986]

There is an oil refinery about an hour away from me, pass it all the time at work. Went there to check it out they have a museum about the history of it, cool place. Anyway, all the powerlines running above the refinery were covered. Any of ya had to work on lines like this before?

Ummmmmmmmm yes I have. its some heavy stuff. basically its primary cable in a armored jacket and suspended from a messenger by using a spinner. Its pretty big around .......... I used some with 3 phases of # 2 copper, 15kv pri, each with a # 6 neutral and the diameter of the cable was a lil over 2 inches.Many refinerys are using this stuff. If not on poles then in a cable tray. I have aslo seem some with 3 phases of 500 69kv and that stuff is close to 5 inches in dia. and stiffer than all get out.

Yea kinda hard to tell from the pic but that stuff had a thick diameter

The funniest part, to me, was next to where ya parked there were some pretty big transformers, had the sticker on the side "do not hump" . Now i know what it actually means. But the kid inside me had a good laugh

Now I know what it means on a box car, but what does it mean on a transformer?

The refinery work is a whole new ballgame.....first you can be searched when entering and leaving the plants....lighters are not allowed in the ones Ive been in.....smoking is in designated areas....they have this ( thing ) that resembles a car cigarette lighter that lights your cig......lots of poles are those h-frames.....like the guys said,the wire is in a jacket...and hung by the messenger.....you use these triangle looking rollers to pull in wire....al in all its simple..even boring,at least for me....the voltage we were working on was 34.5.......also in a plant,or the one that I worked at.....you always had the sierens going off and you all would have to meet at a certain area in the plant.......and there might be 10....15....20 or more areas that people would gather at.....until the all clear signal was called.....some of those workers didnt know anything about the linework we talk about in here,banks,phasing,troubleshooting,ect....like I said its really different.....there was a plant next to that one,where I could talk to the other lineman working for that plant,but as we talked there was a high chain-linked fence between us.....they had normal un-insulated primary at their plant,we didnt.

If the transforner was shipped via rail. That rail car wouldnt have been humped. Prolly never took the sticker off

Yea that stuff does sound mighty different. That refinery there is conoco-phillips. Used to be Shell. Idk who it was you did the work for. Gives ya a reference maybe. Yea, i can imagine a place like that if things went bad they would go BAD!
