Danotherm traction brake resistors provide the perfect solution for use in railway braking applications. The reason for using traction resistors is that mechanical brakes tend to wear out quickly and are expensive to maintain. It is possible to install resistors on top of the vehicle, under the vehicle, or inside a specially constructed compartment.
Traction brake resistors are steel grid resistors built using steel grid plates fitted together into steel grid blocks. The choice of steel and alloy varies with customer requirements. The grids are manufactured by punching and laser-cutting machines and are then assembled into resistor blocks. Steel grid resistors are compact, reliable and robust, and can operate indoors and outdoors.
Traction brake resistors from Danotherm come built according to customer specifications, including voltage, power, mechanical forces, dimensions, ambient conditions, shock and vibration, and national and international directives.
AC working voltages range from 15 kV to 25 kV, and DC working voltages range from 600 V to 3 kV.
Traction brake resistors cool through natural convection or forced air cooling.
Our traction brake resistors comply with multiple railway application standards, including IEC 60322:2001, IEC 61373:2010, ANSI/IEC 60529-2004, UNE-EN 50124-1:2001 and UNE-EN 50125-1:2001. Acceptance tests, if required, can be performed at an external test facility and can be witnessed by an accredited third-party certification institute.
