Effects of MV and HV cable capacitance on operational ... transmission does not suffer from the same problems as AC. DC transmission has its own additional costs, primarily converter stations. The insulation requirements for DC cables are lower than for AC and hence costs are lower. HVDC transmission systems are normally associated with overhead lines but cable-based systems have been developed.
