Higher voltages accommodate longer module strings. A 1.5 kV system can accommodate 33 modules rated at 45 V of direct current, while a 2 kV system can fit 44 modules – representing a 33% ...

The 2X25 KV system works by distributing the voltage along the line at a higher level (50 KV) and feeding the train at 25 KV. This is achieved by providing power from Traction Substations (TSS ...
