Contact wire

Product Description

Contact wires form the primary current-carrying interface between the overhead electrification system and the pantograph of electric rolling stock. These wires are designed for high conductivity, wear resistance, and consistent electrical contact at operating speeds.

Key Advantages

• High electrical conductivity for efficient power transfer
• Excellent wear resistance against pantograph contact
• Stable cross-sectional geometry
• Reliable performance at high operating speeds
• Long operational life

Available Variants

• Grooved contact wire of various sizes complying with relevant standards
• Copper contact wire
• Copper silver contact wire
• Copper tin contact wire
• Round bottom contact wire
• Flat bottom contact wire
