Steel wire ropes for solar field support: Strength and efficiency in the service of solar energy

At the heart of a solar field, where thousands of photovoltaic panels capture the sun's energy, lies a silent but vital network of steel wire ropes. These wire ropes, far from being simple structural components, are the invisible pillars that support the infrastructure and ensure the efficient production of solar energy.

Function and characteristics to be fulfilled by steel wire ropes for support in solar fields​:

• Support: Steel wire ropes act as the backbone of the structure, providing support and stability to the solar panels. They must be of high strength to withstand the weight of the panels and the inclement weather.
• Weather resistance: Wire ropes must be designed to withstand extreme weather conditions, including rain, snow, wind, extreme temperatures and prolonged exposure to the sun.
• Corrosion resistance: The material and sheathing of the wire rope must be corrosion resistant, especially in saline or high humidity environments.
• Flexibility: Wre ropes must be flexible enough to allow easy installation and maintenance, without compromising their strength.

Types of supporting steel wire ropes​:

• Galvanised wire ropes: The cheapest and most common option, but can be susceptible to corrosion in salty or humid environments.
• Stainless steel wire ropes: They offer higher corrosion resistance and longer service life, but are more expensive than galvanised wire ropes.

How to select the right steel wire rope for photovoltaic structures?

The choice of the right steel wire rope for a solar field depends on a number of factors, such as:

• Size and weight of the installation: The wire rope cross-section should be proportional to the size and weight of the installation to ensure adequate support.
• Climatic conditions: The material and sheathing of the cable must be suitable for the climate of the region where the solar plant will be installed.
• Type of structure: Cables for overhead structures should have higher strength than cables for ground installations.
• Budget: The cost of steel wire ropes varies according to material, cross-section and manufacturer.

Steel support wire ropes are essential components in the construction of solar fields. Their function is silent but crucial, providing support and stability to photovoltaic panels and ensuring the efficient production of solar energy. Choosing the right wire rope and installing it correctly is key to ensuring the durability, safety and efficiency of these installations, driving the transition to a more sustainable future.
