At Unex we have been offering products for routing, tying and fixing cables in the photovoltaic sector for more than 15 years in different countries and applications: solar plants, solar roofs, floating photovoltaic plants, agrovoltaic, solar canopies, inverters, etc.
In addition, we have more than 45 years of proven experience in outdoor installations all over the world.
Electrically insulating material.
High dielectric strength, protection of people against the risk of electrocution due to indirect contact.
The cable trays and trunkings eliminate grounding and equipotential bonding issues.
The insulating material prevents leakage currents and electric arcs between the cables and the cable trays or trunkings.
The cable trays and trunkings protect the wiring, improving the performance of the installation and extending its service life.
Cutting the products does not produce burrs that damage the insulation of the cables.
The cable ties have high tensile strength according to EN 62275.
Over 45 years of experience in outdoor applications.
Resistance to prolonged exposure to ultraviolet rays, thanks to the specific formulation of the raw materials.
Resistance to environmental corrosion (humid and saline) and to chemical agents.
No need for earthing or maintenance.
Easy to assemble and install.
In photovoltaic installations, cable ties are the fundamental element for fastening and fixing cables.
The cable ties used must be especially resistant to weather conditions, high temperatures, and prolonged exposure to ultraviolet rays.
The formulation of our raw materials allows us to meet the most demanding technical requirements with both Cable ties 22-0 and Cable ties 22 HD.
If you have a photovoltaic project and need information about the durability of our cable ties, contact us by selecting the ones that interest you the most.

A solar farm is a fixed or tracking installation made up of a set of solar panels installed on the
This type of installation is characterised by:
Plant shutdowns, maintenance and the commuting of professionals generate high costs and reduce performance.
Distributing, protecting and tying the cables with products that meet very demanding technical requirements is essential to extend the lifespan of the plant and maximise its benefits.
Rooftop solar photovoltaic installations are mainly intended for self-consumption in the industrial, tertiary and residential sectors.
In this type of installation, easily accessed by anyone, stable electrical safety over time is essential. The use of products in insulating material protects the cables and guarantees electrical safety for both people and the installation.
Insulation is even crucial when the rooftop is metallic (in corrugated sandwich panel rooftops), where the insulating material electrically separates the installation from the building structure.
To improve the lifespan of the installation, it is important to protect the cables from the elements and from all types of birds and rodents, with electrically insulating products, making the installation twice as safe.
The cable distribution is carried out through protective trunkings installed on the surface. Depending on the type of rooftop, different supports are required, such as:
For a few years now, floating photovoltaic plants have been gaining importance, and these have a number of advantages over ground-mounted systems:
Among the main challenges of this type of installation are the high electrical risk caused by humidity, environmental corrosion, and the high maintenance cost, as these photovoltaic systems are located on lakes, ponds, reservoirs, the sea, etc. For this reason, the products used for cable protection and fastening must meet very demanding technical requirements that ensure electrical safety and protect against indirect contact.
Agrovoltaic energy is positioned as a fundamental axis to make agriculture a more sustainable sector in the fight against climate change.
Distributing, protecting and tying the cables with products that meet very demanding technical requirements is essential to extend the life of the plant and maximise the performance of solar agricultural self-consumption installations:
Installations in solar canopies are key to the energy transition, and there is an increasing trend towards this type of self-consumption in which the space dedicated to vehicle parking is used for the installation of solar panels.
Depending on the type of photovoltaic canopy, the needs of the electrical installation may vary, which is why the products for the distribution, protection and tying of the cables must be versatile and easily adaptable to each structure.
Other essential requirements for the products used in this type of photovoltaic installation are:
Solar inverters are a very important element in photovoltaic installations and an inadequate choice of cable protection elements can cause electrical failures and reduce the performance of the plants.
It is important to use insulating products that provide maximum electrical safety and protect the cables from the elements and from all types of birds and rodents to improve the lifespan of the photovoltaic system. In this way, we achieve a twice as safe installation.
In addition, the insulating products make installation easier, as they do not require grounding or maintenance and are resistant to corrosion and weathering.
Unex insulating solutions are backed by over 45 years of experience in outdoor installations, remaining unchanged even under the most demanding conditions: direct exposure to weather, ultraviolet radiation, or the presence of pollutants.
With experience in photovoltaic installations around the world, our products have proven their effectiveness and durability even in regions with the most extreme weather conditions.
