Hey mate!
Here's your answer!!
Advantages of Underground Power Cables
1. Safe Operation :
If we consider about the advantages of Underground Power systems for power distribution and transmission. Normally underground power cables are safer than the overhead power line. So the probability of the hazard occurrence is very less.
2. Good General Appearance :
The appearance of the underground cables is really good than traditional overhead lines. Since it located underground there is no such visibility of the line for people. So in most urban cities and highly dense domestic areas, this type of cables are widely used to have a better appearance compared with overhead power lines.
Disadvantages of Underground Power systems
1. High Capital Cost:
One of the major disadvantages of the Underground Power systems is its initial cost. Compare to overhead transmission or distribution the cost for construct underground system is extremely high. So since it has more benefits, this main disadvantage is the main cause for there is very less underground cable practically apply in the power industry.
2. Can’t Use for High Voltage Levels :
Another disadvantage is due to the time the insulation can get weaken so an air space can form inside the insulation. Since the power delivers on high voltage level the air inside getting ionized and the lead the breakdown of the insulation. So due to this problem the underground cables are considered only suitable for the distribution on voltage level up to 11 kv and fewer values.
Hope it helps you.
