telephone and power line


What are options about running a phone line in the same trench (or conduit) as feeder line to outbuilding?

what can I do to protect or minimize interference?

metal conduit or maintaining as much distance between the two lines as possible. At least a foot separation but more if at all possible

In addition to this, there is shielded cabled available at least for networking, and networking cable can be used for phones. Not positive if any of it is direct burial rated.

Jamie is right, you can get shielded cable but it has to be in conduit. You can buy shielded u/g cable but expensive.

Phone can't be in the same conduit as power unless the phone wire has the same insulation ratings as the power cables. If you have phone cables with a 300 volt rating then it could be in the same conduit. It is virtually never done that however.

Twisting both lines one or two turns/foot will reduce 60 Hz on your phone but that may be practical only for the phone line. It's called a twisted pair.

Nonmagnetic shield foil or braid is only good against E [electric] field interference.
In this case the interference is caused by the H [magnetic] field. Thick steel/iron is more costly and more effective for this type of shielding. For problem applications they use mu metal.

on the bright side, you can buy a wireless phone system from WallMart for less than $ 40, then no need to bury any wire

Yes, the radiated energy is not so high that you can expect brain cancer or eyeball cancer, in the near future.
