Behind every safe and well-organised electrical installation, there is an element that often goes unnoticed but plays a crucial role: the cable trays. They can be grid, perforated and blind, ladder or even self-supporting systems. Their applications are varied and they come in different families, but they all have a common purpose: to support and protect cabling, to ensure order, and to provide long-term safety and durability.
We spoke with Daniel Redondo, director of PUK Portacables, who shares his commitment to a legacy of more than three decades. With a clear vision and commitment to the company's core values - quality, customer proximity and honesty - Daniel explains how these guidelines remain the basis of its strategy as the company moves towards new goals for 2025.
Christmas brings with it sparkle and magic through a myriad of decorative lights that make everything extra special. However, these installations can also become a challenge if not handled well.
Each project has unique needs. At PUK Portacables we know this, which is why we design solutions that adapt to each situation. It is not simply a matter of choosing a cable tray system, but of designing a solution that integrates seamlessly into the infrastructure, ensuring safety, operational efficiency and long-term durability.
Connectivity has been key to the progress of our society. From the first telegraph signals to the advanced 5G technology we know today. This evolution has not only transformed the way we communicate, but it has also made it necessary to have physical systems that support this entire information network. This is where cable carrier systems have played a crucial role, adapting and evolving along with each technological advance.
In our day-to-day lives, we rarely stop to think about what's under our feet. While we connect to networks, use our devices and manage electrical systems, there is often an essential infrastructure that goes unnoticed: underfloor trunking systems.
Data centres, smart buildings, industrial facilities, offices... In any of these places it is essential to have good connectivity that brings daily business operations to life. Therefore, an infrastructure with the right technology and good data transmission is essential for the efficiency and success of any project and even for carrying out our daily lives.
Cable clamps are an essential part of both the integrity and stability of cabling. These small components play a key role in organising and securing cables, preventing them from shifting or being subjected to unnecessary stresses that can affect their performance. Without the right clamps, cabling can be exposed to all kinds of threats, compromising the long-term performance of the system.
High summer temperatures mark a critical period in firefighting. During these months, the risk increases significantly due to factors such as heat waves and the intensive use of electrical systems for cooling and other purposes.
The hottest months of the year are here, and in addition to enjoying them, it is crucial to take preventive measures to avoid problems in the operation of the wiring of our installations.
Efficient mobility is a prerequisite for any society. To this end, the expansion of transport networks requires increasingly sophisticated and efficient infrastructures. In this respect, transport and traffic systems have never been as complex and interconnected as they are today.
Support structures for solar panels are one of the main elements of a photovoltaic installation. They not only ensure that the panels are firmly attached to the surface, but also guarantee their correct orientation and inclination, allowing the system to make the most of all that solar energy has to offer.
Choosing the right cable management system is essential to ensure the performance, efficiency and safety of any infrastructure. At PUK Portacables, we have been advising customers in various industries for more than 30 years, and they trust in the reliability of our products and services.
In any environment where cable management systems and underfloor systems are used, safety is a top priority. More than just supporting and managing cables, our products have a duty to protect them, ensuring their integrity and preventing risks of damage or failure. Therefore, complying with safety regulations and standards is essential to ensure a quality product and a safe and reliable working environment.
The leading Spanish newspaper has interviewed our general manager and deputy director, Daniel Redondo and Sandra Redondo. In an exhaustive article that reviews the history of the company, the media has highlighted PUK Portacables as one of the most important companies in Spain in the manufacture of cable management systems.
PUK Portacables has been located, for more than 30 years, in the heart of the dynamic industrial network of Baix Llobregat. Its headquarters are strategically located in Abrera, just 35 km from Barcelona, in a 2,000m2 warehouse that benefits from a privileged environment with access to some of the main transport and trade routes in the country.
Effort, resilience in the face of adversity... these are some of the values that define PUK Portacables as a company and also as a team. That is why we have decided to take a new step in this direction and sponsor an athletics team, specifically the CA Sant Andreu de la Barca.
In the industrial environment, safety is the top priority. Therefore, the selection of anti-slip flooring is a crucial measure to prevent accidents and guarantee the integrity of workers.
Cable trays are essential elements in the cabling infrastructure of any building or industrial facility to ensure the support and protection of the cabling. Among the materials most commonly used for their manufacture are galvanized steel and stainless steel, which stand out for their unique characteristics and durability. But which one is more suitable for each type of project?
The best solution for cable management, organization and protection in electrical installations are cable trays. They play a crucial role in ensuring the integrity of the cables and, therefore, guarantee the safety of both the installation and the people who are responsible for fixing and maintaining them.
Renewable energies, electric mobility, conservation of natural resources... These are just some of the many initiatives that are emerging to ensure a more sustainable future for our planet. The fact is that we are increasingly aware of our environment and, above all, of the role we play in improving it. In this sense, energy efficiency has become a central theme in the fight to curb climate change and reduce greenhouse gas emissions.
This week we have appeared in one of the most important media of our country, the newspaper El Mundo, where we have had the opportunity to talk about our products and solutions adapted to different sectors.
Proper installation and maintenance of the electrical system are key to avoid overloads and other types of breakdowns, both at home and in large infrastructures.
