ZENER, a benchmark in the Telecommunications sector since 1985

1985

ESTABLISHMENT

Zener was founded in 1985, and shortly afterwards, despite its young age, expanded the activities making use of the opportunity provided by the fast technological progress.

The company starts to work in the deployment of TV links, repeaters, and radio stations with satellite reception.

1998

EVOLUTION

With the progress of fibre optic networks, ZENER became a pioneer in the design, construction, installation and maintenance of HFC (hybrid fibre coaxial) cable networks and began to create alliances with the main regional cable companies such as Retecal, Telecable, Madritel, Tenaria, Ono or Canarias Telecom.

Faced with new growth perspectives, we diversified our activities, specialising in the deployment of mobile telephone networks, making use of the 2G, 3G, and 4G technology.

2000

NATIONAL GROWTH

The emergence of FTTH technology (Fibre To The Home) provided ZENER with a great opportunity to grow, strengthening the collaboration with telecommunications operators (Vodafone, Orange, Telefónica, MásMóvil, Grupo Euskaltel ...) at a national level.

The company decides to pave the way in new sectors such as energy, civil works and security.

2010

INTERNATIONAL PROJECTS

The ambitious goal to internationalize the company takes us to start performing projects in Portugal, France, Peru, Brazil, Chile, Mozambique, Algeria or Thailand.

This jump to the international stage made it easier for our Renewable Energies Division to grow. We have implemented more than 460 MW in Spain, Italy, Belgium and the Netherlands.

EXPANSION
