Insulator Washing on Energized Transmission

[kenbob]

I was wondering what type of washing equipment you all use on washing insulators on energized transmission lines. We currently have a Chance Insulator Washer (high pressure water) that you can no longer find parts for any more. We are contemplating purchasing one of the dry cleaning systems. Is there one out there that anyone has used that would allow us to wash on lines up to 345kV??

Thanks for your help.

Where are you at , Alot of salt??? alot of mist alot of both ???

Only one i seen in action was at a FPL substation. it was a high pressure washer. It is my understanding they have one now that "blows" a non - conductive dry chemical.Can anyone help out?

Sounds like a very unhealthy mix of airborne solvent and oil.

We have 2 rigs built and we use distiled water in the from the power plants

Are any precautions taken to prevent the distilled water becoming contaminated? It only takes a little bit of dirt to increase the conductivity dramatically.

The water washing systems I've seen, use a pulsed spray so there is not a continous water path back to the nozzle. But read the warning!!! The one I used said to not let the nozzle get closer than 3 feet so that one pulse of water couldn't bridge the gap.

I don't much fancy that! What if the device that pulsed the water failed in some manner and shot a continuous stream?

I'm thinking more of the ionized arc flashing cloud that will form and connect between a pulse and/or ground/phase in the event a mishap occurs. But I could be wrong.... Perhaps it's all in the chemical? The distilled water thingy just isn't sitting well with me...

Look MA NO HANDS! - That looks like a foldable clamp/hot stick to me not a blow tube device. However I must say you do indeed put a lot of faith in dem booties your wearing let alone no gloves... Thanks for the PIC!
