Solenoid of tram switches
The solenoid of tram switches (solenoid) is designed to ensure the movement of the rods of the solenoid type switch drive.
The solenoid of tram switches (solenoid) is designed to ensure the movement of the rods of the solenoid type switch drive. The solenoid provides linear movement of the ferromagnetic core when converting the electric current passing through the coil into a mechanical pulling force.
Solenoids are installed directly in the switches of tram tracks.
The solenoid design provides protection for the IP67 solenoid coil and the IP44 solenoid mechanism according to GOST 14254-96.
In terms of resistance to the effects of climatic factors, the resin corresponds to the climatic version – U, category 1 according to GOST 15150-69.
The average service life is at least 10 years.
