The current capacity is based on maximum tolerable heat / temperature rise. Nothing else. In fact this is precisely why long haul transmission is done at such high voltages - to keep the current low for a given power transfer. | |

| Aug 2, 2019 at 5:24 | comment | added | Neil_UK | Aare you sure about that @analogsystemsrf . Given that the cooling is a function of length as well, for a straight wire shifting power from A to B. Now if the wire was bundled up like a wire wound resistor, that would have a constant thermal resistance and power and temperature rise proporiotnal to length. | |
| Aug 2, 2019 at 5:14 | comment | added | analogsystemsrf | the length of the wire determines the total thermal resistance, thus the temperature rise. | |
