In the end, it’s not just about generating more power, but about smart grids that can transport it reliably and with minimal losses.

## The problem: Old grids for a new energy future
|

Today’s power infrastructure was built for centralized large-scale power plants. But renewable energy works differently: It is decentralized, weather-dependent, and requires flexible grids. This creates a massive need for restructuring.

Without the right cables, electricity stays where it’s generated. But what kind of grid expansion really makes sense?
|

### Underground cables vs. overhead lines – which is the better choice?
|
||||
A key question in grid expansion is whether new power lines should be built as overhead lines or underground cables. Both options have pros and cons, but in the long run, underground cabling offers significant advantages in terms of reliability, environmental protection, and grid stability.

In the past, overhead lines were favored due to lower construction costs. However, modern demands for grid stability, environmental protection, and aesthetics increasingly support underground cables. As a result, many countries are now adopting underground cabling as the standard for new high- and medium-voltage power lines.

Particularly with cables such as **NA2XS(F)2Y** or **NAYY** for **wind turbines**, the choice of material determines costs, performance and service life. Copper impresses with its high electrical conductivity, while aluminum scores with low costs and low weight. But which material is technically and economically the better choice in the long term? This article provides a detailed analysis of the advantages and disadvantages of both options.
|
||||
### Electrical and Mechanical Properties Compared
|
||||
Copper has been the preferred material for electrical wiring for decades. It offers high conductivity and excellent mechanical stability. Aluminum, on the other hand, is significantly lighter but has lower electrical conductivity. This means aluminum cables require a larger cross-section to transmit the same current.

Although aluminum offers weight savings in transport and installation, it requires larger cross-sections to achieve the same performance. This can impact space requirements in cable trays and mechanical stability. Additionally, aluminum is more prone to oxidation, which can lead to contact issues, whereas copper maintains its conductivity over long periods without significant quality loss. In humid or salty environments, such as offshore wind farms, this can be a crucial factor.

Without a well-thought-out recycling concept, vast amounts of wood, steel, and plastic would go to waste. However, efficient solutions already exist to return cable drums to the raw material cycle and minimize environmental impact.

### Materials and their reuse

Cable drums are made from different materials, each offering unique recycling possibilities. The way they are reintegrated into the circular economy depends on whether the material can be directly reused or needs further processing.

Depending on their condition, cable drums can be directly reused, repaired, or dismantled into their individual components. Wood, in particular, offers versatile reuse possibilities, while steel and plastic serve as valuable raw materials for new products.
|

To prevent raw material waste, it is essential to view damaged cable drums not as disposable waste but as a valuable resource.
