It must be a single continuous cable, no Henley blocks or similar as
they are points where unmetered electricity can be taken from.

Why can't they solder/weld (I'm not sure that soldering is still the
right term given the size of the cables!) with a sleeve over the top
(and put it in a box if they're worried about mechanical strain relief
- but the point is it would end up as a solid joint)?

Surely that would be no more and no less tamper-proof than the actual
cables either side of the join?

They used to solder massive cores in the street[1] - I believe they
usually crimp them these days.


Can you believe the soldering involved pouring molten solder from a ladle
over the cable and ferrule and catching the runoff in another ladle -
all while the cable, and ladles were live whilst sitting on a rubber
mat...

it was called "jointing". I watched them do it in the late '50s.
