Can Bare Cooper Busbar Surfaces Be Cleaned/Polished?

08/25/2008 8:28 PM

Is it O.K to clean/polish bare cooper & aluminium busbar surfaces (of rectangular section in are) with electrical cleaning solutions, eg. Electro Sol. Or, are there other better methods of cleaning/polishing bare busbar surfaces, if technically permitted.

Is this for surface preparation before bolting or joining busbars together, or general cosmetic maintenance to keep existing busbars nice and shiny-looking.

Hopefully this is after the busbars are deenergized?????

I'm still wondering what cooper bus bars are. Is that where all the Coopers get drunk before catching the bus? Or is it maybe barrel shaped bus bars? Or...? Wait - I just noticed those naughty Coopers are bare. I guess that bus is going to the nudist colony.

In some of the crowded areas of the larger cities traffic is a problem for commuters. In these areas enterprising people have devised ways to make commuting a little less painful. Shuttle busses will bring groups of people from a central point in the suburbs, to another central point in the city. These busses allowed a commuter to relax and read the paper, catch up on some work through a laptop.

In order to lure more riders their buses, operators started to offer more luxuries. At some point the "bus bar" was installed. In order to out do each other the bars became more elaborate. And thus was born the Brass Bus Bar.

In Miami last month they busted a bus that was equipped with small rooms and hookers. True story. Check out Miami Herald on web.

A taxi driver in Vegas went on and on about a start up called boob and lube.. It was supposed to be a place where you could get an oil change and.. more. He was going on and on about the investors and the other odd business's involved..

maybe I should google it.. I'm afraid it must have all been a taxi driver story... He was killing my brother and I with this story.

_______________________________

fast forward to future....

OMG... OK.. I did the math, and Google it for you.. the truth 'was' stranger than remembered! yikes is all I can say

______________________________________

found this .. then had to stop looking.. ___________________

One-stop BOOB & LUBE: Pizza/Lube Adult Entertainment and Laundromat

I'd forgotten all about this until the story hit the local papers, and it's a fucking riot. About a year ago, this guy, this hillbilly redneck idiot, takes out a series of ads with our paper for his – I shit you not – One Stop Pizzeria, Express Lube and Laundromat. This is a shack out in the middle of nowhere on a two-lane highway between two of the sleepiest little backwoods towns in Tennessee, Baxter and Gainesboro. I wish to god I still had a graphic of his ad. It was simply indescribable: in addition to the pizzeria and oil and lube, there was a tanning salon (ONLY $29.95 per month!) and full service laundromat. But our entrepreneur was just getting started...

Shortly after his ads ran, we got word that he had opened a strip-club – first the "One Stop Gentleman's Club and Sports Bar" and later the "Costa Rican Beach Club" - on the premises. To put this into some sort of context, you have to realize that there are only about a thousand households in all of Baxter. People around there expect to see deer and wild turkey, not wayward titty-bars popping up in the woods like crack-ho's from some dank corner of Nashville.

The main act consists of his Brazilian wife, fresh from her stint as cashier at the Pizzeria and Oil Change place (for all I know, she changes the oil, too), now swinging her titty-tassels for the occasional traumatized soul who wanders in looking for an oil change or to do his laundry.

The story in today's news is a comic gold mine:

Because he opened the club at nearly the same time that the county adopted the Adult/Oriented Establishment Registration Act, Flatt said it was legal because no adult entertainment codes were actually in place when he opened, while the county said that the Adult Registration Act was in place before Flatt opened the Costa Rican Beach Club and it fell under the authority of the Act.

The county took Flatt to court for a decision on the matter.

"This is killing my business because the girls have to wear bikinis," he said. "There's more skin shown on HBO than in my place."

In March he told the Herald-Citizen that he was going to close the businesses and hold a public auction in April.

But today Flatt said that no one showed up at the auction and he decided to reopen the One Stop Market and the new Club 56. He closed the One-Stop Lube shop.

"There's no more boob and lube," he said. "I did hate that name but that's what everybody called it."

He says now that he has plans for expanding Club 56 to include a dance floor.

"People can come there to have music, food and fun. If they want to eat and dance they can, if they decide they'd like to watch the girls they can just walk to the show."

A friend works with a sand blaster using Dry-ice to clean electric motors, maybe it would work for you as well.

Good luck

If the buzz bars are not removed and cleaned any residue around the edges where they are mounted could start a chemical reaction which could damage the buzz bars.

Any cleaning in my opinion should only be done once removed.

If cleaning while mounted I would use no chemicals. A good clean ground is hard to keep.

ok, we've got bars in buses so I suppose getting a buzz at the bar was sure to follow.

I would rather get a buzz in a bus bar than a buzz from a buss bar.

Commuters getting buzzed while commutating on a bus bar.

An electronics professor of mine told a story of being stationed in France at a radio transmission facility while in the Navy. The CO, being ALL NAVY, wanted everything clean and shiny in the transmitter building, especially the bus bars. After all the oxidation was removed the transmitters were down on output power. Something to do with the conductive properties of the oxidation layer and high frequency. I don't recall the details. The CO was transferred.

Jaguar, If nothing exceeds like excess, does nothing succeed like success?

Does that make congress the opposite of progress?

Sure just use a little "Never Dull" and the cooper (um I mean copper) should clean right up. While you are at it, ALL those little stripped ends of wires need tending to as well. They also get pretty nasty at times.

For safety reasons I would contact the power company and have them shut off the local power grid, and to have a line tech on site to drain static from the line while work is performed. They might even be able to suggest or supply an anti-corrosion ointment to apply to the those nasty little buggers.

Remember, an arc-flash protection suit and equipment is a must when restoring power to the system as well.

The photograph below is a Tympanic crystal compound in Trifid mass and bus bar.

There is a very precise scythe (hard circle on disk rim) in the Trifid bus bar, this maybe an event horizon of a black hole.

In layman's terms I think that this maybe construed as...................if you touch the Trifid bus bar and it is not isolated..............there will be a black hole..........this is where you disappeared through the wall of the main switchboard room!!!!!!

................but I do not recall any bus bars in "The Day of the Trifids"

Use something like alcohol that will evaporate and leave no residue. I do not know if denatured or isopropyl is best.

Alcohols have no effect on copper oxides.

You could just use a wire brush or sandpaper to physically remove the oxidation.

Have you thought of a low powered blasting application with walnut shell media to clean the surface and wires? Just a thought.

Too bad the previous 14 posts are so shitty. A simple, reasonable technical question begets trash replies. Grow up guys.

Permissible so long as surface finish and dimensions are not altered no sanding or grit blasting unless finished with finer and finer to original 600 grit or finer state. DC much more forgiving of surface finish. High frequency can be very particular and you should consult a specialist in waveguides if you are above 60Hz. Must keep 'crevices' at joints free from any 'wicking under' of solvents or ? to avoid potential for a corrosion cell to form.

What is the cause of debris requiring removal? Normal copper patina is OK. Heavy corrosion is not--cause needs to be corrected. If cleaning to prepare for a connection, follow exact directions accompanying the connection kit. Very high amp, low voltage connections--such as electrolysis power supplies, often use special paste containing silver 'grit' to ensure as close to zero resistance as achievable.

"Too bad the previous 14 posts are so shitty. A simple, reasonable technical question begets trash replies. Grow up guys."

Regarding the last 14 posts, lets see: one guy suggested a dry ice blasting, another walnut shells. a couple of suggestions for chemical approaches. One for a good old wire brush. Any of these might work well.

And some humor thrown in as we once again prove that engineers can't spell. Appropriately labeled as "off topic."

You suggest blasting or sanding (no media specified) and then prattle a bunch of "specs" without reference. And your answer is superior because...it is verbose? It sounds pompous?

I suggest you get a sense of humor and a life. Then lean that your vulgarity isn't appriciated and is certainly not professional. But nice to see we have an expert amongst us.

I believe that trying to assure that the busbars were deenergized (post #2) before Zippy gets zapped by following orders that don't take the hazard of electrocution into consideration is worthy of much less contempt than "shitty."

Protect the customer...from himself... is my first cardinal rule.

rereading the navy guy post, i could see some well meaning idiot ordering the busbars to be well polished " You there- give him a hand here with that ladder ..."

FLASH!

Fatality.

I think you need to acquire a sense of humour my friend................life is not easy for many in this corrupt, debauched world..............a little humour makes the world go round..............it may prevent you from going insane...........it certainly helps me and probably many others.

It is not needed in most cases as copper oxide conducts, how ever aluminium oxide does not conduct electricity. When attaching wires or bars etc. made of aluminium apply nlux or some other cream to seal the connection. Make all connections electrically tight and mechanically secure.

Around here, Electro Sol is actually dishwasher detergent. Our electricians clean using denatured alcohol because it leaves no residue, but I don't know how effective it is at removing corrosion. And, as mentioned, DO NOT TOUCH energized circuit components!

Dilute phosphoric acid works well as a soldering flux on cooper copper, by removing the oxidation film and shining it up before the soldering operation takes place. Try that on a piece of scrap cooper copper first. Car body "rust remover" is an easy commercial source of small quantities and is available retail at most high street motor parts outlets. It can be applied typically using a small paintbrush. Low-level eye and skin protection, and possibly protective clothing, would be of benefit during this activity subject to a local risk assessment taking place beforehand.

In the absence of proprietary dilute phosphoric acid, one of the popular "colas" available in the local supermarket may well work as, in the absence of proprietary phosphoric acid, there is enough of this substance dissolved in the drink to substitute for soldering fluxes.

Why people drink so much cola given that snippet of information is a complete mystery here. No doubt SolarEagle is already looking for an informing, entertaining and educating video on YouTube...
