Job hydroelectric

A negative-temperature hydroelectric power station with an air-hydraulic conversion drive operates in the “winter” mode in the temperature graph of negative ambient temperatures, i.e. when the working water freezing mode in the power working cylinders of stations using cold energy will create an overpressure for the operation of hydraulic actuators.
