Overhead Contact Line Materials: Contact Wire, Stranded Wire
The overhead contact system is a crucial component of the electrified railway traction power supply system, continuously supplying power to electric locomotives. Typically installed in open-air environments, the overhead contact system is subjected to various harsh weather conditions and must also withstand the dynamic forces generated by the moving electric locomotives. This requires the contact wire materials (contact wire and messenger wire) to possess high strength and high conductivity, and the contact wire, in particular, which is in direct contact with the pantograph, must also have high wear resistance.
As a leading global supplier of overhead contact line wires, our company can provide customized product solutions based on our customers’ application scenarios, meeting the needs of high-speed, intelligent, and green development in the railway industry through improved product performance.
- Copper-silver alloy contact wire: Speed 160 km/h
- Copper-tin alloy contact wire: for speeds of 200-250 km/h
- Copper-magnesium alloy contact wire: Speed 350 km/h
- Copper-magnesium alloy stranded wire: Speed 200-350 km/h
27.5KV Cables and Cable Accessories
Electrified railway 27.5kV cables + cable accessories + distributed fiber optic temperature monitoring system
We provide complete power transmission system solutions.
The cable has a rated voltage of 27.5kV and is suitable for electrified railway systems. It is primarily used for AC single-phase, power frequency, 27.5kV electrified railway lines, autotransformer power supply lines, and feeder lines leading from traction substations, sectioning posts, switching stations, and autotransformer stations. It features excellent radial waterproofing performance and can be installed in damp environments.
- To ensure the electrical performance of cross-linked polyethylene insulation, our company takes the following measures:
- It utilizes a fully dry, three-layer co-extrusion cross-linking process;
- Maintain long-term, stable strategic partnerships with suppliers to provide high-quality insulation materials;
- Online monitoring of the thickness and eccentricity of the insulation layer and semiconducting shield layer;
- Control the thermal elongation of the insulation of the insulated wire core to ensure the degree of insulation cross-linking.
