Guess the cable

[johno12345]

Hi,

Since I am stuck in work today I thought I would add a picture of some cable that we are having altered about a bit.

It was installed in 1969, the diameter of the core is 1.74mm tinned copper. Other than that, has anyone come across it before?

If somebody guesses it straight away, I will be mildly miffed!

Is it the equivalent of FP200?

 

[johno12345]

isnt FP200 multicore? This was supplying a ring circuit....

 

[oharaf]

Sorry, some of the 'older' alarm cables came as singles.

You sat this came from a ring final mmmmmmmmmmmmmmmmmmmmm!!!

Is it

1. Phase

2. Neutral

3. CPC

Recently removed something very similar from a house whilst doing a rewire- this was singles, fabric and 'rubber' coated supplying the un-earthed lighting circuits

 

[johno12345]

It is phase, there is no CPC as it is done in steel conduit.

The only other type of cables to this board are PVC SWA clipped direct.

The majority of the circuits are done with this cable, we have red, white and blue. It supplies lighting, extraction fans andd control panels. It is in excellent condition, no signs of breaking down.

The reason I posted is because it has been mis-identified many times by time served electricians....

VIR singles cloth covered, rubber insulated and tinned conductors due to reaction with rubber?

 

[Lectrician]

Yup, loads of old factories had this in the trunking/conduit.

I am amazed stuff like that has been used as lately as 1969.

 

[johno12345]

looks can be deceptive

I will reveal all later on

close our boiler room exploded in the great propane boiler explosion when somebody purged the propane lines with propane instead of nitrogen then pressed the ignition button. Since the room was demolished I dont know if any was fitted there. This is used in our warehouses with an ambient of 40c in winter and 50 plus in summer.

As I said, it runs our high-bay lighting, sockets and control panels the cables close to the furnace are all pyro. Some fool installed cab tyre flex on some of the furnaces, needless to say, it is a little scorched.

Anyway, its FP100

Incidentally, to maintain temperatures like that with the roller doors open and no insulation, we burn £60,000 of gas per week!

It doesn't look like this either:
FP 100 Link 1
FP 100 Link 2

 

[johno12345]

It is on the plans drawn in 1969 and they specify FP100. Presumably it doesnt look like new FP because it has been updated...
