Yes. For starters, the power cables are legally required to be in
conduit of their own, and with good reason.
Not quite correct.
Separation is mandatory and protection is recommended.
"Protection" can be as simple as tanalised timber above the cable.
Of course conduit is highly recommended though for lots of good reasons.

When I 'undergrounded' my street feed I was advised to bury the cable
directly in the ground for the cooling effect of the earth. If I had
used a conduit then I would have had to use the next larger wire size.
The price difference was significant to me at least. I imagine for
3-phase the difference will be even greater.
