The railway industry is undergoing rapid changes in the quest for energy efficiency, increase of economies, reliability, effectiveness and quality of railway transport.
Today’s railroads evolve in to an evermore high-tech industry. Whether it is rolling stock, services, system and signalling, including railway related telecommunication equipment and infrastructure, many challenges are being faced throughout the market.
We offer an extensive range of passive electronic components for railway equipment, including IGBTs, MOSFETs, thyristors, diodes, resistors, capacitors, high voltage semiconductor components, fuses, heatsinks, low temperature capacitors and rectifiers.
Within our development teams, we have the knowledge and the skills required to meet customers’ needs. Our global presence means we operate wherever you do and we can support your project worldwide. Our focus on the railway supply industry allows you access to the widest selection of standard and customised rectifiers, IGBTs, MOSFETs, thyristors, diodes, heatsinks, high voltage semiconductor components, converters, liquid cooling systems, power electronic building blocks and capacitors.
GD Rectifiers supports Great Britain’s leading railway providers such as Network Rail, Transport for London, Cross Rail, passenger and freight operating companies, rolling stock organisations, main infrastructure contractors and many other buying organisations in the management of supply chain risk.
Railway manufacturers and contractors are seeking further efficiency savings in the full range of electrical components that meet low life-cycle costs. Our passive components, including: rectifiers, high voltage diodes, heatsinks, filters and capacitors enable increased productivity and capabilities. This improves operational availability and control of on-going maintenance costs.
Railway Equipment & Applications
We’re proud to have our products used in the following rail applications.
IGBTs are used across a wide range of railway traction technologies.
Provide auxiliary power supplies in the railway sector.
Gate Turn Off Thyristors (GTOs) are designed for railway traction systems.
Fuses are used in main and signalling circuits at railway stations.
HV Diodes are usually used in overhead signalling lines and on the tracks.
Heatsinks (or heat sinks) are used to provide LED lighting on the platforms.
Capacitors are used to track the presence of the trains on the rail tracks.
Rectifiers are used for railway DC traction systems.
Resistors are used across trams, metro, light rail ad high speed trains, they all need resistors for different kinds of applications.
Trackside converters are fed with energy from overhead line, they supply various loads in substations, including power supply for integrated lighting and information systems, railway signalling and protection systems.
These offer high quality and reliability that significantly increase traffic availability of passenger coaches.
They convert voltage from generators in to the drive power for the traction motors, three-phase auxiliary power supply for the train on-board consumers and into DC auxiliary power supply for charging train batteries.
Supply the main and auxiliary drives of trams.
These are used for supplying the main and auxiliary drives for locomotives.
Liquid cooling systems are usually designed for installation in the traction converter, the liquid cooling system uses water to cool the converter power modules.
Power Electronic Building Blocks
Power Electronic Building Blocks (PEBBs) are subsystems for traction converters, they are liquid cooled building blocks designed for propulsion converters in traction applications.
