Underground Cable – Introduction and Construction 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. But the use underground cable offers a variety of advantages. Some of the advantages are listed below. It is less liable to damage during storm or bad whether condition. Offers low maintenance cost. Less voltage drop during normal operating condition and less chance of fault. But the main disadvantage of underground cable is its cost of installation. For higher voltage the cost of cable increases due to greater requirement of insulation as compared to overhead lines. Therefore, it is installed in area or localities where overhead lines cannot be installed. Requirements of Underground Cable There are various types of cable available but the choice of particular type depends on the operating
