Estel Ingeniería y Obras is a specialised company with a long history, which makes us one of the undisputed leaders in the implementation of installations for electricity and telecommunications, both within our borders and on a global level. Since the beginning, our industrial and international team of professionals has focused on incorporating the most advanced solutions in these fields to optimise available resources and meet the expectations of our clients. The result has been the execution of hundreds of comprehensive projects all over the world, all of them undertaken using the latest advances available on the market and without losing sight of the responsible and sustainable attitude we always apply to our projects.

Electrical systems, lighting, multimedia, sound, renewable energy, networks… Our efforts are always aimed at offering a complete management and execution service where we adjust every required action down to the millimetre, backed by professionalism and innovation for each project. This is how we have become specialists in giving the best response to every kind of undertaking, among other examples in projects related to substations and transport lines, medium and low voltage, all kinds of lighting (artistic, decorative, public…), railway electricity and the development of energy efficiency solutions and solutions that respect the environment (cogeneration and trigeneration plants, photovoltaic panels, biomass plants etc.).

Along the same line, the execution of telecommunication installations has become one of the company’s main pillars, and alongside this the work we carry out in the fields of telecommunication networks, wireless, television and radio network transport systems, works related to audio-visual projection, sound, PA-systems etc.

Our commitment to continuous improvement in the provision of services has also led us to introduce the most advanced techniques available in the telecommunications area, such as GPON technology (Gigabit Passive Optical Networks) and FTTR technology (Fibre To The Room, which allows a multitude of services to use one single cable). It is worth remembering that these two techniques represent a technological revolution that greatly impacts the accommodation and hotel sector, a sector that has used Estel’s comprehensive services to a great extent when implementing installations (as evidenced by the fact that the leading companies in the sector – Marriot, Barceló, Tryp, Iberostar, Meliá, Hilton… – have relied on us and our performance time and time again).


These new technological approaches have replaced conventional copper-structured cabling solutions, and thanks to them customers can benefit from the following:

  • Lower installation and maintenance costs
  • Improvement in data speed
  • Connections with all peripherals (television, Wi-Fi, security sensors, telephones…)
  • Single IP connections

With an eye to the future, Estel’s main objective is to continue combining long experience (more than 20 years in the business) with the latest advances to ensure the most complete solutions when it comes to integral installations. This in the field of electricity and communication as well as in home automation and control, mechanics, hydraulics, air-conditioning and special installations.
