Can anyone guess an work this out

You lot should have gone to specsavers. It has Raychem branded on it!! They were founded in 1957 so it is definitely after then.

The heatshrink over the cores which has been added after they stripped the outer servings and lead sheath, probably earlier today, you mean?

Looks similar to the 95mm2 triplex I'm used to seeing. But a copper core rather than aluminium core. (More than likely due to costs) View attachment 28109which we use on our 11kV systems.
I am still a sparky in training, but the copper "sheath" on the outside is connected to earth, and isn't used as a power carrier.

What isn't clear from the picture is that the lead sheath and outer servings have been stripped back and the red heathshrink applied over the cores. The triplex you can see in the trench underneath is presumably what is going to be jointed onto the cable.

Raychem produce heatshrink termination kits and joints for just about every type of generally used MV/HV cable past and present.

What were seeing in your photo is a cable end in preparation of being made off, while in the OP's photo's, it looks like nothing has been done to prepare the cable. In fact the more i look at those photo's i'd say that the original joint has been cut out, the Raychem heat shrink is a dead giveaway that these ends were once part of a terminated joint or even a termination into an enclosure...

Once you’ve been to Secsavers read #12

Yes I'm sure you're right Tony, I just saw thick strands to begin with but realised that's not likely. I can't see how it would have been made for DC and then re-purposed for AC, unless it was 3-phase DC and then it would only have been for LV, as HVDC was the province of special systems like the Oxford 2kV system.

I'm also keen to know the present working voltage.

I’m not convinced that is 11KV, 3.3KV maybe, I think you would be pushing your luck at that.

Most 3 wire DC was 2½c so I think the DC idea has gone out the window.

Unless the OP comes back with some more information we’re wasting our time. Interesting non the less.

Talking of Specsavers and Raychem, anyone spotted the break out. Normally a three turret boot would be used for MV.
