When it comes to railroads, timeliness and safety are the primary concerns. The safe movement of trains, the elimination of costly delays, and the providing of reliable and satisfactory railway service are all dependent on the communication and signal circuits. These circuits must function even under the most adverse weather conditions, and it is important to use high-quality, strong conductors that assure the required mechanical and electrical properties.
Fushi Copperweld line wires provide railway communication and signal lines with the safety and dependability essential in all phases of rail operation. The high strength of Copperweld wire is particularly valuable for railroad communication and signal lines. Our wires withstand heavy ice and wind loads on open lines, and permit the use of less sag and longer spans without sacrificing safety and dependability. With high-strength steel at their core, Fushi Copperweld’s line wires are stronger than copper or bronze, but with the copper layer carrying the both the power and the signal, the conductivity remains quite high.
Genuine Copperweld line wire is available in two conductivity grades, 30% and 40% of the conductance of a copper wire of the same size, the choice depending on the application. Copperweld’s conductance is relatively uniform over a wide frequency and current density range so that the reproduction of voice and data signals is faithful and fidelity is not lost. It is one of the few high-strength conductors suitable for telecommunications operation.
The wire’s strength and conductance are maintained throughout its long life of the wire thanks to the thick, corrosion-resistant covering of copper inseparably welded to the steel core. Fushi Copperweld wires are available bare or with any of the standard coverings or insulations.
