Pioneering Electrical Infrastructure
E.T.E. began commercial operations in 1988, installing and commercializing telecommunications and electrical materials. Starting as an invited contractor for EDP, we quickly expanded into low voltage infrastructure, renovations, and power connections.
By 1992, we advanced to medium voltage aerial lines (30kV) for EDP. In 1993, Portugal Telecom pre-qualified us as a recommended contractor for exterior telecommunications networks.

In 2000, E.T.E. completed the Quality System implementation process and obtained ISO 9002 certification through SGS ICS. We have maintained our accreditation continuously since then.
Our effective Quality Management system ensures that every project meets the highest standards, from initial planning through final delivery and beyond.
