Pyro

[sammyshooter]

Morning guys, bit of nostalgia for you vets.

Wiring up an MOT bay, went to see the excavation so we can draw up the plan, they pulled some pyro out that was buried 1.5m deep, and was amongst a news paper that had a 1970's date on it.

Gave it a whirl on the tester for banter, still returning <199 Ohms on insulation test between live conductors!

Been battered by the jcb as well.

Either you don't understand what a good result is on an Insulation tester or your not aware of how to express it in print... hope you don't fill the cert' out!

Insulation test >199 Mega-ohms is what I think you meant.

 

[Pete999]

Strip the ends back about 6 or 7 inches and you will probably get an even better IR reading

I think the OP is expressing how good it still is even after been battered (last line) ....so suspect he doesn't know how to represent the reading in text.

Glad to hear your pulling out dodgy cables, sell it for scrap!

My bad, it was early

And yes, just expressing it's resilience

Or perhaps Megohms! ;-)

Don't think any of the old hands here will be in the slightest bit surprised by that finding. A MICC cable installation installed by competent electricians will out live the installer and his children, even if taking a few bashes over the years, so long as those bashes don't penetrate the sheath.
Probably the best general small to medium multi core cable size system ever produced

Rather work on Pyro any day rather than steel conduit

 

[tazz]

No manufacture todate has been able to produce a life saving cable, equal to MICC

 

[snowhead]

I'd be shocked if it wasn't still good.

 

[7029 dave]

No surprise to me what so ever. I have flattened an piece of MICC, put an blow torch to it, then IR the piece, still of scale reading.!! ( experiment of course).

 

[Andy78]

I am not surprised either. I have seen a test similar to 7029 dave's above. Quite astounding the abuse it will take.

 

[tazz]

Shown this video many times on here, but may help newbies to micc.....you can skip to 5.30 for cable test fp200 vs MICC

[Redvanman]

I use to love doing MI but sadly I don't have any call for it now.

 

[tazz]

There is still a major call for it in Chemical, gas production....apart from its fire proof properties, its ability not to compel gas or fluid is another bonus

 

[Silly Sausage]

........... its ability not to compel gas or fluid ....................

Eh? :confused5:

 

[tazz]

ok to prevent a capillary reaction within the cable....

 

[Andy78]

MI.... thwarting the effects of fire since 1938
