Specialized for performance
Although the requirements imposed on contact line systems for main-line railways are complex, the answer is simple:
Siemens offers a number of systems to ensure utmost performance on main-line railways:
• Sicat HA – the high-end overhead contact line for the highest speeds up to 350 km/h
• Sicat SA – the economical alternative for high speeds up to 230 km/h
• Sicat HD – the overhead contact line built for DC systems and running speeds up to 230 km/h
• Sicat SD – for the extension and upgrading of existing overhead contact lines for DC railways up to 160 km/h
• Sicat SR – the overhead conductor rail for installation in tunnels and under bridges
• Sicat SX – the cost-efficient electrification solution up to 250 km/h
Sicat HA – for the highest loads
The development of Sicat HA focused on high speeds, reliability and interoperability. So our designers created a contact line system that caters to running speeds over 300 km/h and to a power transmission of 20 MW per train with good traversing characteristics. For the highest speeds, we use a design with optimized stitch wires, spans of up to 70 meters and a tension length of 1,500 meters.
Internationally certified
Sicat HA is certified as a component in general and as a subsystem in specific projects for the trans-European highspeed rail system. This overhead contact line is ideally suited for interoperable railway lines because it allows simultaneous use of the most common and different types of pantograph in Europe. Sicat HA overhead contact lines not only surpass all requirements in respect of temperature range, current-carrying capacity, wind speed and fouling, but are also extremely robust and wear-resistant.
Sicat SA – economical and reliable
We have developed the Sicat SA as a overhead contact line system that is perfectly suited for new and extended highspeed AC railway lines around the world, as well as for all types of upgraded conventional lines and line extensions in the trans-European high-speed system. Thanks to the lower electric loading and technically less demanding power transmission in existing route networks, Sicat SA offers more technical design options for open lines, tunnels and stations for speeds up to 230 km/h. Sicat SA convinces users not only with its low wear but also with its low investment and maintenance costs. It is certified as an interoperability component under TSI Energy.
Sicat SX – for cost-efficient electrifications
Sicat SX is an inclined catenary system for main and secondary lines in main-line railways with outstanding dynamic traversing characteristics up to 250 km/h. The system is characterized by simplified arrangement of overlaps, longer tension sections and greater span lengths and based on proved standard components of Sicat contact line systems from Siemens. Because of low investment costs and maintenance efforts the life-cycle costs of Sicat SX will be favorable for AC railways. Sicat SX has also been certified under the European rail system interoperability directive and the associated Energy TSI as an interoperability component.
