Our activities


We support all our clients in their project design. Depending on how advanced your project is, we can either just advise you on specific subjects or entirely design the whole system to meet your needs.

COSYSTEC is independent from manufacturers; this guarantees that you will get unbiased advice from us. You can choose the equipment manufacturer you want for all or part of your cabinet.

We systematically endeavour to find the most economic solution that corresponds to standard requirements, whether this be for switchgear, protections or cables.


Dedicate yourselves to setting up and organising construction works. COSYSTEC will make your cabinets and deliver them fully equipped and ready to use, under one sole name.

We work in close collaboration with manufacturers to offer our clients innovative solutions that meet their needs. Our various official quality seals guarantee top-level quality of service.

Electric cabinet and panel wiring is our core business, and we also offer numerous services and products in connection to it.


As our technicians are trained and have electrical certification, they can carry out tests directly on site. Depending on the importance and scale of the project, these tests can take place before or after cabinets are connected and in the presence of representatives of the various trades involved.

We can also help you optimise industrial high- and low-voltage electrical networks. To compensate reactive energy, you can choose from our range of capacitor banks.

For maximum service continuity we have various UPS systems that can best adapt to all types of installations through exclusive technology.


COSYSTEC proposes engineering, preventive and corrective maintenance, audit and advisory services to its clients. Renowned for its reactivity and organisation, COSYSTEC is a trustworthy partner. We design, produce and maintain low voltage installations:

  • Electric cabinets
  • Distribution
  • UPS systems
  • Capacitor banks
