Press Release - CG receives GL Renewables certification for its Slim Distribution Transformers

  • SLIM® and Bio-SLIM® Distribution Transformers from CG offer most efficient solutions for wind farm offshore platforms
  • Bio-SLIM® is the latest and most advanced environmental friendly transformer solution by CG
  • Market for offshore wind farm to grow by 9 times to 51 GW by 2020*


Mechelen, November 28th, 2013. Avantha Group Company, CG was awarded the certification from Germanischer Lloyd Renewables Certification (GL RC), for its liquid immersed SLIM® and Bio-SLIM® distribution transformers. The testing for adherence to certification norms was carried out according to GL`s Guidelines for the Certification of Offshore Wind Turbines, Edition 2012. The transformers are hermetically sealed with bio-degradable fluid which reduces the risk of pollution at environmentally sensitive locations, such as offshore wind farms.


The certificates are valid for five years (2018) and were provided for two of CG`s components: the SLIM® and BioSLIM® Distribution Transformer KNAN, (up to 3500 kVA, 50 Hz), and the SLIM® and BioSLIM® Distribution Transformer KFAF/KFWF (up to 6500kVA, 50 Hz).The certificates were rewarded for CG`s superior system design, the implementation of design requirements in Production and Erection (IPE) and quality system. Prototype tests were conducted as a part of the Design Assessment of the components. Incidentally, CG also received the GL certification for the onshore market in 2012.


CG has grown to become the market leader for transformers in offshore wind farms. As of today more than 1.000 units have been installed worldwide in offshore projects. CG is one of the world`s leading manufacturers of three-phase transformers, offering a full range of products including liquid-filled distribution transformers and power transformers, auto-transformers, phase-shifters and HVDC station transformers, conventional and mobile substations.


According to GWEC (Global Wind Energy Council) 5.5 GW of offshore capacity was installed accumulatively worldwide at the end of 2012. According to more ambitious projections up to 80 GW could be installed worldwide by the end of 2020.


CG`s SLIM® and Bio-SLIM® distribution transformers offer the most efficient solutions for wind farm offshore platforms - they promise reliability, fire safety, longer life time and low maintenance, withstanding severe harshness of the environment, general cost of installation and maintenance.


According to Holger Trecksel, Head of Sales and Business Development GL RC said "The certification demonstrates that CG`s transformer has been designed, documented, manufactured and tested in compliance with the latest technical requirements documented in GL RC`s Offshore Guidelines."


Commenting on the certification, Avantha Group Company CG`s CEO & Managing Director, Mr. Laurent Demortier said, "The Wind offshore sector is one of the fastest growing segments within CG. We are committed to provide our customers energy-efficient, cost-effective, reliable and best-in-class solutions. This GL RC ` certification demonstrates the adequacy of SLIM® and BioSLIM® Distribution Transformers to withstand the specific harsh environment at the Wind offshore power projects."
