resistors > Breaking resistors for transportation engineering 3PQ & 6GN1systems

Among the resistors mounted on the outside of the vehicles, two types are available: Dachwiderstände und Rooftop resistors and Unterflurwiderstände zu unterscheiden. Underfloor resistors. Rooftop resistors are often easier to cool but mostly result in aerodynamic and optical problems. Underfloor resistors are problematic in terms of heat dissipation, in particular during standstill after braki
