Miguélez Cables

Our history

Our history begins in 1951, with the foundation of the Miguélez Company. Since then, we have grown to become a worldwide leader in the manufacture of low voltage power cables.

Throughout these more than 70 years of experience in this industry, we have based our daily work on values that have remained intact since the beginning: commitment, devotion, excellence, transparency in all operations and teamwork.

Our sole objective: to provide the best service to all our customers. For this purpose, we have the latest technological advances and more than 450 professionals distributed throughout the world, because, in Miguélez, we have always shown a clear international focus and a high level of adaptation in each one of the new markets in which we operate.

2006 - Founding ofMiguélez Chile (Chile).
2007 - Founding ofMiguélez Panamá (Panama).

At Miguélez, we look to the future. Together, we will make it possible.


Our ongoing search for excellence in logistics has led us to the implementation of a customised distribution system, which is supported by a permanent stock of the models with the highest turnover rate in each one of the markets in which we operate.

All this combined with our extensive network of logistics centres allow us to shorten delivery terms, speeding up the supply of the merchandise.

In addition, the more than 420 million running meters of cable manufactured each year and the more than 4,295 models in our catalogue allow us to meet the requests of our customers quickly and efficiently.

In Miguélez we have a modern main manufacturing plant of 64,500 square meters located in León (Spain), a new logistic center of 33,000 square meters located in Villadangos del Páramo (León) and 14 logistics centres that form the largest interconnected network of cable warehouses in the world:

- In the main Spanish cities: Madrid, Barcelona, Málaga, Murcia, Valencia, Vigo, Zaragoza and Gran Canaria.

- In Europe: Lisbon (Portugal) and Paris (France).

- And in America: Panama City (Panama), Lima (Peru), Miami (USA) and Santiago de Chile (Chile), where we have another production centre.

Innovation and sustainability, with the guarantee of a great manufacturer

In order to achieve that excellence in terms of quality, a key point is the effective management of business relationships with our suppliers. Therefore, in Miguélez, we establish a Business Code of Conduct where we convey our policies and values, and we ask for their compliance.

Corporate Social Responsibility (CSR)

As a company committed to the environment, Miguélez is involved in numerous initiatives in the electrical industry for the preservation of the planet, as evidenced by our active collaboration with several environmental committees of different agencies and institutions, both public and private.

Our environmental actions are reflected in the establishment of an EMS (Environmental Management System) in accordance with ISO 14001. MIGUÉLEZ has established different organizational guidelines to guarantee the correct classification of the waste produced during the manufacturing process of an electric cable. All these wastes are delivered to authorized managers in charge of applying the different disposal or recovery operations (recycling, reuse and recovery) of the waste. Moreover, our commitment to the environment is not limited to the management of industrial waste, but also to the implementation of production systems and to products and packaging that are more respectful with the environment.

Therefore, all of Miguélez cables meet the RoHS Directive on the restriction of certain Hazardous Substances in electrical and electronic devices, thus providing effective and sustainable solutions.

MIGUÉLEZ thus ensures that the environmental impact of our products and our industrial activity is the minimum possible. You can download our Quality and Environmental Policy here.
