Changhong/Nickel Cadmium Battery/Ni-Cd Battery/Rail Transit/On-board/Telecommunication
Changhong Nickel Cadmium battery for rail transit application is specially suitable for emergency and general lighting of vehicle, metro and light rail train, signal on rail intersection, driving power of safety fence, emergency lighting power for railway station and subway station, as well as diesel engine starting.
Changhong Nickel Cadmium battery can conduct normal operation under the temperature at -40℃~+70℃. The battery can be discharged 70% of rated capacity by 0.2ItA.
Technical Advantages
Long service life, the battery can reach the best life cycle cost after over 5000 times charge and discharge.
Compact volume, high specific energy, convenient for improving carrying capacity of vehicles.
The reasonable structural design not only ensures the reliability of battery leak proof structure, but also is convenient for monitoring the electrolyte state.
Adopting the new valve control type assembling vent plug avoids the decrease of water, prolongs the maintenance period of the nickel cadmium battery, guarantees the performance of Ni-Cd battery and extends the service life.
Selecting the optimum density potassium hydroxide solution(high purity) as electrolyte reduces the internal resistance of the nickel cadmium battery, improves the performance under low temperature, big current discharge and high temperature charge.
Super high charge-discharge efficiency, lower water consumption.
Free maintenance, in general, at least within 3 years no need to conduct activating treatment during the whole operation period.
