Transport / Railways

Our customers include a wide range of companies in the Nordic transport sector.

Components for transport and railways

 

Transport and railways are important parts of our infrastructure, enabling both people and goods to be transported in an efficient and environmentally friendly way. For trains to work well, they need advanced electrical systems. Swelex offers components for rail and transport - our customers are companies throughout the Nordic transport sector.

Electronic equipment for trains

 

Swelex offers some of the most important electronic equipment in train systems: DC/DC converters, AC/DC converters, DC/AC inverters and cables.

DC/DC converter
DC/DC converters are devices that convert one level of direct current (DC) to another level of direct current. In rail transport, these converters are used to:

  • Stabilising voltage
  • Efficient energy distribution
  • Protecting the train against voltage fluctuations

AC/DC converter
AC/DC converters convert alternating current (AC) to direct current (DC). These converters are important for trains because they:

  • Enabling the use of AC infrastructure
  • Supplies the train's electrical system with direct current
  • Improves energy efficiency

DC/AC inverters

DC/AC inverters convert direct current (DC) into alternating current (AC). These inverters are essential for rail transport for several reasons:

  • Operation of AC motors: Many modern trains use AC motors because of their higher efficiency and reliability. DC/AC inverters allow these motors to be powered by direct current generated by the train's pantograph or batteries.
  • Energy efficiency
  • Flexibility in energy supply: They allow the use of different energy sources, including batteries and regenerative braking, which can store surplus energy to be used later.

cabling

We offer wiring harnesses that ensure the correct connection and operation of the train's electrical components.

  • Power cables: From pantographs to motors and lighting.
  • Signal cables: To transmit control signals between different electronic components and control systems.
  • Communication cables: enable data transmission and communication between the different systems of the train and external infrastructure, such as signalling systems and traffic management.
  • Proper installation and maintenance of wiring harnesses is essential to avoid downtime and ensure optimal system performance.
