Σύνοψη

Utilities are faced with the need of using effectively
conducting media for transferring power from substations to other substations and consumers. An essential part of
Utility networks are the Underground Cables.
A considerable amount of transmission and distribution ,
especially in urban areas is carried out by means of
underground cables. In the present time electricity supply
authorities are been force, from the growing public , to
preserve the amenities of both town and countryside .
Because of these problem the supply authorities considerer
the under-grounding of many circuits which they would
prefer on economic grounds to place overhead. Even in
sparsely populated regions, high-voltage bulk transmission
circuits have been placed underground where areas of
outstanding beauty exist.
Under-grounding cables must take into consideration a lot
of parameters. First of all if another method can be used
(overheat), what kind of cables must be used, if the cables
are be installed at the proper high under the earth, if in the
case of a fault the fault can be repaired easily and fast, the
cost of the network. These are only few of the questions we
must think before under-grouping any cables.The purpose of the work is finding out these parameters that
affects under-grounding the power cables. To try finding
the best solutions for these questions.
