Conductivity (IACS)<br />
Depending on whether strength or electrical conductivity is the most important,<br />
the appropriate alloy will be chosen. This choice will reflect mechanical design<br />
parameters of the catenary system and the electrical power supply. It is up to<br />
the system designer to select the right alloy taking into account factors such as<br />
speed, traffic frequency, required lifetime, maintenance and power supply.<br />
