PCB oil filled switchgear

Tony needs his fix of old gear!!

Here's one for you...... A prime example of old gear in bad shape!!

Think he's far more interested in the bigger LV stuff, or better still older MV switchgear!! lol!!

Makes you wonder, again, what substances we are all freely using today which in 20 or 30 years will have been found to be hazardous.

I wonder this myself...

You know me to well!

At least now you have more information via COSHH.

When I started the PCB scare was only really getting rolling. We removed a lot of PF capacitors, probably even ones that were safe but we weren’t sure so they had to go.
Disposal has to be at extremely high temperature, unfortunately there were the fly boys that didn’t stick to the rules.
Now PCB’s for disposal can be blended in to liquid fuel used in cement kilns. Along with old tyres and all kinds of other crap. Don’t worry about the cement, the temperature required to make it is so high all traces of the PCB are destroyed.

If anyone remembers the EMEB’s HV training collage at Ashover Hall a most of the transformers were PCB filled. When it moved to Radcliffe, the transformers had to go for disposal as they couldn’t be transported to the new site for reuse.

http://www.midel.com/ Midel is king, never had one fail (granted the trannys were well looked after) its less harmful blah blah.

Only thing is that it's quite a bit more expensive.

Yep, thought i recognised the name, that's the stuff our distributions tranformers have been filled/supplied with on previous projects, and probably will be again on this project.

Like I said every time we tested it on site passed with flying colours all tests and usually above 55KV.
Great stuff, it should be the standard imho.

Yep anything above 30KV on 11KV and 60KV on 33KV systems is all good!! Depending on what head shape electrodes are used in the oil test kit...
