Here are some specific applications where HVDC transmission provides some technical and economical benefits compared to AC transmission schemes The potential for long distance transmission in particular for long underseaunderground cables transmission schemes typically when there is a long submarine cable link 40 km Long underseaunderground highvoltage cables have a high electrical capacitance compared with overhead transmission lines because the conductors within the cable are surrounded by a thin layer of insulation The geometry is that of a long coaxial capacitor Thus the total capacitance increases with the lenght of the cable This implies that the maximum feasible length and power transmission capacity of HVAC cable is limited As AC cable lenght and voltage increases the capacitance and hence the AC charging current increases in proportion the charging current is the current flowing just to charge the line See Answer
