Contact Wire (Cu-Ag/Cu-Sn/Cu-Mg Alloy)for Electrified Railway

Application
Contact wire is a electric conductor of an overhead contact line with which the current collector makes contact and is characterized by two clamping grooves. Copper and copper alloy grooved contact wires can be used in railway applications, Fixed installations and electric traction.

Description
The drawing stock or intermediate rod stock is a copper or copper silver as defined in standard EN 1977 or a copper cadmium, copper magnesium or copper tin alloy.
Note:
1)To identify the different copper(alloys) used as contact wire, identification grooves are used.
2)Whatever cross section of the wire is used, the dimensions of the clamping grooves shall be in accordance with standard.
