  • Description
  • Parameter
SPECIFICATIONS:
1. Cu-Mg alloy stranded 
2. Copper stranded wire 

APPLICATION:

Catenary wire is used as overhead power source for subways, light and heavy transit systems,electrically powered mine trains, buses, and industrial cranes.
Catenary wire can carry a certain current to reduce the impedance of the traction network, reducing voltage loss and energy consumption.

RECOMMENDED For :
* Overhead electrical systems
* Mass transit and high speed systems
* Both AC and DC applications
* Specialized applications for Tin and Silver Copper Alloys
* Light Rail, tram and trolley bus systems
* Overhead traveling cranes
