Problems of underground electric cables
Environmental problems:
The installation of an underground power line is a deterioration of the environmental characteristics of the land on which they work.
The excavation of a trench along the trace of the link, the easement requirement of a lateral band switching, access from nearby roads nearby excavations that hold the joints and the installation of substations, reactive power compensation etc ...
The cover and the fact same burial confine the electric field of the wires inside, canceling its effect to any object or person on the field. Problems
operation of underground cables:
The reliability and flexibility of the underground link are substantially lower than those of airlines, given their failure and repair all time are older. In addition, cable links do not support the use of reenlistment, which implies a rigidity similar to operating a generator. Problems
cost of underground cables:
construction costs, labor and maintenance of any underground line are very high compared to the airline equivalent.
