Yes I've been wondering why I can't find many pics of our installs, then realised that they would be mostly be real photos not digital ones, which aren't here at the mo. Anyone remember 'The Electrician's Mate' - a kind of MI user's OSG from the imperial era? I'm nowhere near old enough to have installed imperial cable the first time round but some of the pics in there are quite reminiscent.

It's probably just too costly vs other wiring methods these days.
some of the old guys I worked with worked at dounreay nuclear station for a while.
they would slag of my apprentice attempts at terminating mi and regale me with stories of 19 core imperial mi cables
with 2metre tails for panels etc.
try putting the seal on that sonny!

Same as most I've not done any since college, just remember having to be pretty quick with the tools due to moisture being absorbed

Still got a roller but never used the shrink type. Didn't last long, like that crimp type gland/pot style. When that came out it was the way to go, for about 6 months, then back to the old method.
Remember the first spin strippers coming out ? Great 'till the cutter went blunt.
Then the Joistripper, really was/is a joy.

There seem to have been quite a few variations on the strippers over the years. The one where you had to fit a gland as a guide, the 3-hole 250V one, three sizes of Sheathmaster, ZSU and its little brother ZSUS, the Joistripper. And a few kinds of crimper too. Post pics of any early tools you've still got!

Great stuff, Chemical plants and industrial plants still insist on it, as Fp acts like a straw when it comes to sealing rooms. Come across it all the time in the fire industry. Young lads still wonder why i carry a candle in my tool bag.....well to all the post saying their joist strippers go blunt quickly, this is your answer...

Our company rules prohibited its use on plant. The sheath breaks down if there is any vibration. We did a short trial using it on 24V PX’s. To say it was a disaster would be an understatement. Within the first week two failed due to the sheath cracking.

That said both our site power stations control were wired in pyro. The control was installed by A Reyrolle when the switchgear was installed in the 30’s.

well it does state on the BGB that only a flex/fine stranded cable should be used on vibrating surfaces....
same for vehicles....trailers and the like...

I always thought the BICC handbook suggestion that where you had a motor on slide rails you could just make a little coil of cable to give it some freedom was a bit naive. When I was walking past the FD fan on a steam boiler that had a few turns of something like 3H2.5 attached to its terminal box, I couldn't resist giving it a little twang. It had work-hardened so much it didn't budge at all, it was like glass and I am sure it would have split at the gland if moved. And yet they used MI in ships engine rooms.
