These poles are all fed with 30A 480Volt circuits.
The other issue here?
The Cat5 cables are pulled underground and although they are in their own conduit I don't think that they're rated for wet locations...Remember, any underground conduit is considered as such.
I've used sealtite inside poles before (in much the same way as maintenanceguy) for coaxial cables/cameras...S

Aside to electure -- There is gel-filled/water-blocked RG-6/U and Cat5 4pr UTP cable available for outside/underground use.

I have seen this method spec'ed in plans and specifications.
If I know that power and comm wiring are going to be in the same pole, I run nonmetallic greenfield from a j-box in the hand hole area to tthe lights.
The security guys can worry about signal loss or data corruption.
To get a pole with a divider is cost prohibitive on a bid job. Maybe as a change order once the contract is signed.

Electure,
As long as the conduit was sealed with a solvent cement I don't think there would be a problem.
As Bjarney said, there are cables made to run U/G, but I would personally keep them away from any mains voltage cables, over any long length of run.
Over here, a Telco, stipulates that the power and thier cables must be vertically segregated(in a trench) by 300mm, this is the same for any other "services" (water, etc) that go into the same trench.

Trumpy
It does not matter if you seal a conduit that is underground or not. Water will still get in it. Condensation, ground movement, and ground rodents digging and chewing all cause problems sooner or later. The wire in an ungerground installation needs to be rated for wet service. Most CAT 5 is not.
