Ok..Guys, thanks for the responses:

I live in Panama (Central America). There is an Electrical Code for construction down here and technically speaking it says that power cables should be on their own tube.

Regardless of this, it will be a short run underground of about 30 to 40 feet long. Let us say the cable TV cable is a good quality one such as RG-6 with its own shield and instead of sending two #12 wires (insulated), I go with a 3-wire #12 rubber insulated electric cable (leads: positive, negative & ground). An electrical engineer friend of mine says there are "shielded" electrical cables but these are expensive and hard to find and would have to be ordered to USA (closest place to me), but that this shielding would definitely prevent the magnetic field effect against the signal/communication cable).

I would think that the shielding in the RG-6 cable TV coaxial should be enough to protect against the magnetic field created by the electric wires. On the other hand, the single 3-wire electric cable will be rubber insulated and should be most likely well protected against damages (besides, the tube is 1-1/4" diameter which is more than ample and spacious to fit two cables that are about the diameter of any coaxial cable). Would the RG-6 coaxial cable shielding be enough to protect the internet and cable TV signals from the magnetic field created by electric wires?
