Has anyone come up with a reliable design for wind turbine slip rings so you don"t have to worry about the lead wires coming down the tower getting twisted and possibly failing?? Any pictures and input would be great.. Thanks, Duff Bio Diesel Man

I wouldn't (shoot you) - my 1kW machine went up 23/Feb/2006 and is still running fine, sliprings and all. Thats 6 years so far and no sign of distress either.

Some of the info made it thru ok, but the stuff that didnt we are finding...

Thats the one....mine is nearly identical except i had three rings and run the ac down the tower..
This has been an absolute bomb proof outfit!

cdog · « **Reply #7 on:** March 06, 2012, 07:03:53 PM »

Actually....mine has brushes opposing each other with threaded rod and a coil spring for tension....so i have two brushes per ring...

I was thinking about the 3 slip-ring pictures when I started my search.

Its entirly possible I maybe able to find your pics,

Give me some key words, well see what we find (title of thread etc)

Cdog I can probably help make your link work, if the URL starts with "board.fieldlines" there is a workaround im using. This error makes the page go to the index of the board, anything posted in that timeframe has this directory error, post the link here, "even if it points to the "index page.

cdog · « **Reply #12 on:** March 06, 2012, 07:35:05 PM »

Could dan perhaps send you what he sent me?
I cant seem to do this from my cell sorry...

cdog · « **Reply #13 on:** March 06, 2012, 07:38:07 PM »

Check your inbox i think i just forwarded dans mail to you....

cdog · « **Reply #14 on:** March 06, 2012, 07:39:31 PM »

"2084" would be a good one......

My slip ring at a bottom of a tower for easy access 2 years no problem hope to stay that way.
It is nylon housing with brass rings and fingers ,spring loaded ,pact with silicone grease(electrical).
Inside shaft runs on 2 bearings so it is ease to turn even trough is not spinning a lot, cable absorbs some twist.
Going to 48v allows you to use smaller slip rings and .My brass on brass setup works good and not damaging rings or fingers .

I've got slip rings from a farm pivot irrigator. You might be able to find a used one from a farm irrigator company, lots of them here in the midwest. Rated at 600VAC and high amps. You can see pictures in my "User Diary"; "My 17' So Far"
