Catenary Wire Description
Catenary conductors are a key component of the railway catenary system, transmitting power to the train’s pantographs. They are available in two materials: Bronze II (PADS: 91/012330) and hard-drawn copper (PADS: 91/010269).
The hard-drawn copper stranded conductors consist of 19 strands, each with a diameter of 3.20 mm. The Bronze II stranded conductors consist of 19 strands, two of which are bronze and the remaining are copper-magnesium. Each strand has a diameter of 2.1 mm.
