How the cable industry is driving sustainability and renewable energies forward

Moreover, many materials in today’s cables are significantly more sustainable than they were just a few decades ago. Aluminum and copper from secondary sources reduce the demand for primary raw materials.
This is not just green wishful thinking, but a reality for many cable manufacturers and specialized suppliers such as KLZ. Our cable types – including tried-and-tested cable types such as NA2XS(F)2Y and NAYY for wind and solar parks and classic underground cable applications – are not only efficient, but also designed for durability and, to a large extent, recyclability.

# Expanding the Grid Alongside Demand: Challenges and Opportunities for the Cable Industry
The energy transition brings not only clean energy but also major demands on grid infrastructure. Electricity generated decentrally must be centrally distributed—or passed along decentrally. This means:
- more lines in rural areas
- higher performance requirements due to e-mobility and heat pumps
- more complex routing in densely populated areas
- higher requirements for installation methods such as trenchless construction

All of this can only be achieved with a well-prepared cable industry—in other words, with experts who not only produce and deliver, but also think ahead. KLZ, for example, relies on intelligent availability, clear supply chains, and deep understanding of the specific challenges in wind and solar projects.
Whether it’s medium-voltage cables connecting wind turbines to substations or high-voltage cables for long-distance transmission: the right cable selection, combined with the appropriate accessories (joints, terminations, fittings), determines the cost-effectiveness and sustainability of the entire project.
# The Circular Economy Is Coming – Even Underground
Sustainability doesn’t end with the installation of a cable. Dismantling and recycling are also crucial topics. Especially with infrastructure designed to last decades, it’s worth taking a second look:
- What happens after many decades of operation?
- Can the materials be returned to the production cycle?
- What about the disposal of insulation materials?
