Ice crust on trolley wires may be a problem during winter months - for most transport companies, it means higher expenses subsequently.
The prevention of ice crust formation on trolley wires lies in treating them with a biologically degradable chemical agent applied from the equipment located right on the vehicle. The control system is able to detect the position of the trolley wire while the vehicle is moving and then activate the nozzle using a solenoid valve. Thus, loss of the liquid used is minimised and efficiency increased.
