GE POWEROHM® IC9033 SERIES WIREWOUND POWER BRAKING RESISTOR, P/N 358X636G2.
0.660 OHMS, 1160 WATTS, 42 AMPS: A HIGHER AMPERAGE-TO-POWER DISSIPATION RATIO THAN MOST COMMERCIALLY AVAILABLE POWER RESISTORS.
In dynamic train braking, the kinetic energy of the train is transformed into electric current at the traction motors of the locomotive. Often this system is additional to a friction braking system. The generated current is dissipated under the locomotive carbody in large onboard banks of resistors. Stopping a train requires the dissipation of a lot of energy. Conventional disc brakes alone suffer from too much wear and maintenance.
Brake resistors have relatively low ohmic values and a high power rating. This wirewound resistor has a ceramic core and is fully welded, making it a popular solution for braking systems. The resistors are usually encased in a frame to create a safe distance to other parts. To increase dissipation capability, the frames are often combined with cooling fins, fans or even water cooling.
