Semi-tensioned overhead contact line
Overhead contact line design for winding lines and track yards
Overhead contact line design for winding lines and track yards
Our semi-tensioned overhead contact line with fixed messenger wire makes it easier to electrify winding lines and steep mountain railways. Adapted to the specific challenges of alpine line layouts, this tried-and-tested overhead contact line design ensures a reliable power supply even in demanding terrain, and is both highly efficient and adaptable.
The complex topographical conditions in Switzerland that posed huge challenges for the railway pioneers continue to influence routes today. With small curve radii that often limit the line speed to below 100 km/h, our semi-tensioned overhead contact line systems offer an ideal solution that is both technically mature and economically attractive. Even complex track layouts in railway stations and stabling yards can be easily and reliably electrified with this flexible overhead contact line system.
We have a comprehensive range of components available for these overhead contact line systems to support efficient maintenance and rapid replacement. In addition to standardised solutions, we also offer specialised options such as the inclined overhead contact line – an innovative early patent from our company – as well as project-specific bipolar overhead contact lines for rack railways with two contact wires, which can also be built as semi-tensioned overhead contact lines (with two messenger wires).
With our technical expertise and long-standing experience, we offer customised electrification solutions for all types of railway – including in the mountains.
Planning is carried out using our in-house AutoCAD software ELFF. We are optimally equipped for future-oriented BIM planning (.ifc files) and are continuously working on developing the programme further.
