So, exposure to above-ground electric service from weather, animals and trees is never fully eliminated.

What is the best way to run an underground power line?

There are several different methods for safely running the underground wiring, but the 12-in. deep PVC conduit method we show is about the easiest and most practical for running a typical 15-amp line. A second method, 12-in. deep direct burial of type UF (underground feeder) cable, is another easy alternative.

What is an underground cable?

An underground cable essentially consists of one or more conductors covered with suitable insulation and surrounded by some protective layer. Normally, electric power can either be transmitted using over head lines or underground cables.

What is the difference between overhead and underground cable construction?

While the construction of a new overhead line necessitates underground construction activities only at those locations where the pylons are to be erected, the construction of underground cable systems involves much more extensive excavation work.

What is the best way to bury power lines under soil?

Direct burial of type UF (underground feeder) cable under soil is probably the most common and least expensive method. It provides for hot (s), neutral and grounding conductors all inside a durable, sunlight and moisture resistant encasement or jacket.
