| TITLE | Cable for overhead power lines |
|---|---|
| DESCRIPTION OF THE SOLUTION | The object of the invention is a power conductor for overhead power lines of composite construction, the carrier-conductive core of which is made of copper alloys with high mechanical strength and electrical conductivity, and the outer layers superimposed on this core are made of wires made of pure technical aluminium in the soft state. |
| BENEFITS OF THE SOLUTION | Reduction in transmission losses. Reduction of CO2 emissions. Increase in current carrying capacity. Improvement of electrical conductivity. Increasing the operating temperature limit level of the conductor to higher values than for conventional conductors (i.e. above the typical temperature of 80°C). Reducing the outer diameter of the conductor by increasing the metal filling of the conductor cross-section is beneficial from the point of view of performance parameters such as wind pressure on the conductor or rime load on the conductor. |
| AREA OF APPLICATION | Power engineering (transmission of electric energy) |
| TECHNOLOGICAL READINESS LEVEL | 9 |
