IGBT Module Repair
Insulated Gate Bipolar Transistors (IGBT) are today’s state-of-the-art power electronics for the traction system of rail vehicles. An IGBT module consists of one or more IGBTs and is widely used in assorted industrial equipments due to its exclusive reliability. Top Rail Group builds a unique platform for the repair and maintenance purposes of a variety of IGBT modules, especially for Siemens electric locomotives and CRRC diesel locomotives. This platform has featured the feasibility of repairing and testing IGBT modules in an offline environment, rather than the traditional methods, which have to be undergone on site.

Braking System
Air Brake Module Assembly
At the current stage, Top Rail Group, playing a key supplier role, has been intensively working on the Air Brake Module assembly for HCMT project. The air brake is the standard, fail-safe, train brake used by railways all over the world, with compressed air as the operating medium. Full air pressure signals each rail vehicle to release the brakes. A reduction or loss of air pressure signals each vehicle to apply its brakes, using the compressed air in its reservoirs. Our proficient engineering team is rich of experience and skilled at various assembly services on the air brake modules for rail projects. By applying a comprehensive series of assembly and testing approaches, Top Rail Group will be able to offer quality assurance and simultaneously maximize production efficiency.
