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.

I too have always used a tiny dab of vaseline, never had any problems presented by it.

Well trev it goes against all I was taught, but hey ho each to his own.

Vaseline has a multitude of uses...

I've never used it with micc, I have used it on bus bar joints, isolator switch blades and fuse carrier blades.

I just stumbled across this in activity stream Trev and gave it a double take lol.

Well I was talking about pyro. What's on your mind sweetie

I always thought the tub of lubricant that came in the packet of ends was to help ease the pot on to stop the cable twisting. How many times you heard the screeching noise where someone is forcing the pot on.

You install and dress it properly, you shouldn't need anything lubricant to strip it with a stripping tool, I use a big screw driver on the bigger gear, using a ringer to get the clean edge.

Smaller gear with a stripper, then ring it off against a pair pliers with the stripper.

A bit screwed rod with a slot in it was good for the bigger stuff.
i found a wipe down with an old bit compound aided stripping with a joistripper.
on the subject of Vaseline I got tasked with sorting out the batteries for central battery em light system.
sorted out the cells and went down to boots with my fresh faced first year laddie
asked for the biggest tub of Vaseline they had to funny looks from the boots ladies......

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

What and put some of that even dodgier FP rubbish in it place

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

Might even out live the installers gran kids

and how many explosions have happened by people dropping inspection lamps in to pits?

So it's only inspection lamps that cause explosions

i would expect pits to be at least a zone 2 area now so there shouldn't be any standard type portable inspection lamps used

Rather makes a nonsense of your previous comment

....Why have BICC provided a small tub of vaselin with a pack of 10 terms for the last 30 years. I've not always used it but when I have, a tiny bit on starting the strip hasn't made the slightest bit of difference to the integrity of the stuff....might do if your stripping an inch but I doubt it.

Never used any Pyro terms that came with a tub of vaseline

On the bigger sizes I've always used a piece of 25mm conduit as a stripping bar

Used BICC's MICC for donkey's years, never seen a tub of vaseline in any of the gland/pot seal packs, The MICC seal packs we are using today on this project, also do not contain pots of vaseline.

A damn site safer than that Castrol green switch grease. That was carcinogenic.

On the cement plant we didn’t use any lubricant at all on switch blades. If the dust got in it would set and the switch couldn’t be opened. I was doing pull ups on an EE 800A switch fuse and still couldn’t shift it.

For busbar joints and many other connections it’s great stuff.

Sorry UNG, my post was rhetorical.

 

[stevethesparks]

Not used it for a while, but it was the norm during my apprenticeship. My favoured stripping tool was a piece of 1/4 inch rod with a cut into one end and a handle bent into the other.
I never ever like the new fangled pot crimping tool that was introduced in the 70's, I always preferred the screw-on pots. The straightener was a great tool for a real nice finish.

 

[Jonspark]

Dropping powered up inspection lamps into pits to waiting mechanics has in the past actually killed people.

 

[ipf]

Made thousands of the them off over the years. I'm very surprised many experienced lads haven't come across plastic vas tubs. They came in the packet with the terms.

 

[Anthony S]

The lubricant is for screwing the pot on, I've made off untold ends like yourself.

 

[tazz]

I haven`t to be honest IPF, but would imagine different manufactures either add the oil as a kit.
