MICC / Pyro

[SparkyNinja]

Exactly why does it make any difference whether the compound is filled from one or both sides? As long as it is properly compressed and there are no air gaps, there isn't a problem.

It is deemed better practice method to fill the compound from one side to ensure there is no air trap. Otherwise how would you know?

I don't work with pyro day-in day-out, so I'm sure there are people here far more qualified than me to make these statements. However, in my honest opinion, it sounds like a load of old twaddle. I can't possibly imagine how you're going to get an air gap, unless of course you're not packing the pot tightly enough.

£120 on ebay
I scrapped loads of cable last year, just kept some.
I have 100m of orange 2 core, not sure if 1.5 or 2.5 still in the garage.

Rocky where did you get that book? Been searching google but cant find it?

 

[333rocky333]

Its a 1993 version proberly hard to get one now.

 

[londonboy]

I found it on google

I managed to get 100m of 3L1.5 orange coated off eBay for £120 delivered.

That's got to be a good price right? (please tell me it is!)

I think it was, from what I've seen.

[smug]I did better though.[/smug]

[karma]Always assuming I start to get good IR figures.... [/karma]

I'll post pictures of my first attempts at terminating the stuff, I'm sure that'll be a laugh!

Come on then....

Tip - Throw the 'joistripper' in the bin and get a ringing tool.

Do you mean one of these:

or one of these:

What are the merits/drawbacks of the 3 types of tool?

 

[RF Lighting]

I think it's purely down to personal choice.

I was taught pyro using a joistripper, and that's still my preferred way of doing it now.

You top pic is what I know to be a ringing tool, but it's not something i personally use.

 

[333rocky333]

The top ones a ringing tool

2 and 3 are strippers similar to the joi stripper except you hook the copper round the L shaped hook this peels it as you turn.
They are less likely to bind than the joistrippers.
I use that bigger one on all sizes though its designed for larger sizes realy, the v block is reversible for that purpose.

By holding the pyro with pliers you let the stripper butt up and this then rings offf the sheaving leaving a clean edge.
No need for the ringing tool realy, that is old hat for the days of the bar with the slot in the end.
Although still an acceptable way to do it

Eeeh, all this MICC talk takes me way back to 1988 when I did a load at a new build in UMIST.
