Railway traction resistors

Traction resistors and railway application

On electric traction units, the deceleration force is obtained simultaneously by mechanical braking (shoes and discs) and by electric braking, most often rheostatic, which activates high performance resistors. GRIDEX resistors are used both on TGVs with powerful decelerations, and on suburban trains or trams, which have to brake at very short intervals.
