Brief introduction for KPDS series' railway flat carts powered by low voltage electricity from the railways.

KPDS series' railway flat carts are powered by the low voltage electricity from the railways. The power source AC 380V is transformed to AC 36V three-phrase through transformer. Then they are connected to the three rails respectively(add a conducting rail). The flat carts' wheels and conducting plate lead the AC 36V electricity to the electrical appliance box which is installed on the carts. And AC 36V is transformed to AC 380V through the transformer. Then controls AC Metallurgy motor through AC control system to make the transfer cart start, stop, go forward and backward and so on. This series' transfer cart can be used both on “S” and arc-shaped rails, and high temperature. There can be attached with hydraulic elevator system and lifting system. The cart has the vantages of safety and flexibility. But this series have strict requirement on the construction of the railways which need to be insulated. This series' transfer carts are suitable for the environment of heavy load capacity(>50t),high using frequency and not too short running distance. It is not limited by running distance, but if the running distance exceeds 70m,you need to increase the transformers to make up the voltage which has been lowered.
