Hello friends, I had told in my previous blogging that the current carrying capacity of different UG cables.Today I will tell you how the UG cable is laying and how the cable trench is done with the specification. UG cable is very expensive, about 3-4 times expansive and also laying. But due to many reasons we have to do UG Cable. One of them is because of the reason we have to do UG cable even after being so expensive, is density populated areas where Overhead Network cannot be used. However, the cable should be properly laid because it takes more time to find the fault than the overhead line. Before selecting for laying UG cable, the current carrying capacity, voltage drop and short circuit current of the cable are very important factors which I had written earlier in blogging. Generally the life of the cable is 40-50 years. But Incorrect handling/laying can result in insulation damage and decreases...
