Assembly and installation of ETRA transformers and retention tanks

SONEC offers you turnkey projects including transport, unloading, assembly and start-up of ETRA transformers, supervision of SANERGRID dry-type transformers start-ups, and installation of retention tanks and fireproof covers. We intervene throughout France thanks to our teams, our suppliers’ fitters, and our network of regional partners authorized to intervene in electrical distribution stations.

On-site assistance and technical supervision

SONEC is the first company in Europe to have the KESA label for the supervision of the installation of ETRA transformers under manufacturer’s warranty. Our experts provide factory contact in French on the installation sites in compliance with French regulations. For other SANERGRID design equipment (retention, fire and bird protection, diagnosis and cleaning of high-voltage insulators, drainage water decontamination, etc.), our experts travel to the site to coordinate the site teams.

On-site dimensioning

For your custom projects, our teams go on site to take measurements, analyze the specificities of the site and transmit them to our production engineering.

On-site diagnostics

Our experts in transformers and environmental risks will come to your site to advise you on the analysis of your technical problems regarding the installation of a new transformer, permutations, compliance with standards on retention, fire protection of substations, water law, etc.

Depending on your needs, these services can be followed either by an engineering report describing the recommendations, or by an estimate for the realization of the adequate materials.

Transport and unloading

We deliver our equipment everywhere in France and can also manage the unloading of our equipment thanks to our French partners specialized and authorized to work in electrical substations.

Plans, studies and calculation notes

We draw and design all our solutions on 3D CAD and digital applications at the cutting edge of technology. We are thus able to provide you with drawings in all formats, as well as calculation notes according to your particular requirements.
