Cable required for pulling 3 phase power outdoors
If you run conduit (&quot;pipe&quot; intended for electrical wire protection) you generally use individual wires, NOT cable (several wires bundled in an outer jacket) - they pull easier than a cable, and the conduit is all the outer jacket required, and a better one than a cable has.
Your local standards are undoubtedly in line with most others worldwide in considering any exterior conduit to be full of water all the time. As such, wiring for use in such conduit is &quot;wet-rated&quot; and works perfectly well in water. Your local electrical supplier will have such wire.
If the conduit is to be buried, there are likely standards for minimum burial depth (which may vary with what type of conduit it is) and how it is to be marked. If it is above ground, but below ~2.5m height there are likely standards for what type of conduit is considered sturdy enough for use exposed to damage. I am familiar with those standards in my local area but not in the Netherlands (location per your other question) - however, I'm tolerably certain that such standards will exist locally.
