Element Classification for Overhead Contact Lines

Wiring ( Catenary, Feeders, Conductors)

• safe and secure operation

• wear of contact wire and collector strip

• current capacity ( catenary and additional wires )

���� important for the running speed and train operation

Switching and Insulation

• Sectioning

Use of stitch wire achieves same interaction behavior for:

• increased speed of around 25% or

• around 20% increased span length*

* when not limited by other parameters like panhead geometry

Sicat HA for Beijing-Tianjin Line

- Line nearly complete at viaduct

- Maximum span length reduced to 50 m

- Design without stitch wire sufficient for 300km/h 50 m span length without stitch wire

Customizing – Adjustability of cantilevers

System functionality is equivalent with all designs- Free and unrestricted Uplift >200 mm- Material ( e.g. corrosion free aluminum)- Aluminum design

Sicat cantilevers with different adjustability

Adjustability linked with:

- Compatibility with existing systems- Installation conditions and rules

Customizing with local designs for refurbishments

Sicat elements:

- Wiring (catenary, contact wire, droppers )

- Elements under voltage level and insulators

- Tensioning equipment

Local design :

- Foundations

- Poles, portal structures

- Earthing equipment

- Earthing equipment

- Current return elements

Benefit ����

- Proven and tested design for functional parts

- Corrosion free elements at voltage level

- Usable with local poles, foundations and portals

- Interfaces adaptable to local designs ( e.g. insulator cap )

- Compatible with existing solutions
