Adavntages and Disadvantages of Underground Cables
Apart from designing less optic and environmental crash that produces the huge dissent from the local communities, So the underground cables have many other unique advantages, in separate they:-
Advantages of a Underground Cables:
These all are the advantages of a Underground Cables:-
Have bottom conveyance losses.
Have less maintenance fetch.
Can soak up the emergency power loads.
Release with no electric field and will be engineered to release a less magnetic field than the overhead line.
To install it requires a small band of land.
Low susceptible to the contact of the severe weather.
They have decreased the EMFs (Electric and Magnetic Fields) and therefore removes the potential health issues.
During the Installation the underground cables wiring not disrupts the ground. If it is installed advanced before the landscaping of a new home, it’s even less observable. There will be not any kind of lines that will disrupt your line of vision. Lightning rarely links with underground cable wiring. You do not need worry while you are trimming the tree that you will experience a live wire.
It is very hard to steal, and also very hard to make sabotage or the illegal connections .
There are very less chances to developing the faults and the maintenance costs is very low as well.
Disadvantages of a Underground Cables:
These all are the disadvantages of a Underground Cables:-
The Cost of underground cables are very high (e.g. HVDC).We can say that underground cables cost is three times more compare as to the overhead lines (i.e. 400 KV).
Moreover placing or inter cost of the underground cable lines are much greater as compare to the overhead lines.
In case of the failure of system ,It is hard to discover and fix the wire breaks. besides it takes a lot days or weeks to just overcome with the problem.
The maintenance of the underground cables is very difficult as compare to the overhead because of the underground cabling.
Underground cable lines can not be standard to expand the capacity but overhead lines can easily be up rated to expand more power .
Underground cables are main of the subjected to destruction because of the ground movement required to an earthquake.
An environmental drawbacks also occurs like the person or the another utility doing work in the lawn it will hits buried wiring at the time of digging jobs, for example a tree planting or setting barrier posts. Also the environmental underground cables drawback consist the disruption of soil. So the Settling of the dirt can be happen. You must have a connection box or manhole buried on your belongings.
For the Installation it is very expensive as compare to the other cables such as overhead lines . So for this reason, The underground cables are used very rarely for an entire.
