These applications are at the cutting edge of resistor technology, where customer demands for ever-higher braking powers to be safely dissipated from resistors which have to be compact, lightweight, easily-maintained and with lifetimes to match the locomotives in which they are installed.
TPR Resistors is a part of the Telema Group, the leading European designer and manufacturer of these types of traction resistors for buses, metros and mainline locomotives.
In order to prove and type-test its designs Telema maintains the best-equipped test laboratory of any resistor manufacturer in the world, equipped with a 2 ton capacity 3-axis vibration table, a controlled power source of 1.5MW, and monitoring equipment that allows a fully realistic test of the complete run-cycle of any resistor.
Using our sophisticated 3D modeling and thermal simulation software TPR’s engineers can rapidly offer optimized designs for any application.
