As a cable-free vehicle, the KPD-series Low Voltage Conductor Rail Transfer Cart has high security and flexibility. Since the railway plays a very important role in operating the KPD-series vehicles, the installation requirement of this kind of railway is relatively high compared to that of other kinds of flat carriage. Insulation treatment and compensate copper bars are needed for the railways. Additional step-down transformers are preferred. As a result, the cost of this kind of railways is higher than other types. But as a whole, the KPD-series vehicles are cost-effective and very popular in the market.

For the KPDS-series low-voltage rail-way power-supply carriage, the ground step-down transformer of the carriage can step down the voltage from 380v to 36v, and then links it to the conducting railways. The sliding blocks then lead the electricity to the step-up transformer equipped on the electric flat carriage. After that, the step-up transformer raise the voltage up to AC 380v and then the electric flat vehicles start operating.

In summary, AC 380V is transformed into AC 36V by way of transformer into rails, and then sent to the step-up transformer for triphase AC 380V alternating current to YZ motor.

Notice

1) You have to be sure of rails insulation.

2) If travelling distance beyond 70 meters, you have to add another step-down transformer.

3) For rated load above 100 tons, you have to adopt triphase 36V low-voltage-rail-power-supply and YZ motor.
