1 Energy Trasmission & Distribution Services - Italy Retrofit solutions for plant modernization. Answers for energy.

solutions for plant modernization Retrofit It is a intervention approach that provides the technical upgrade as well as the update of the installed equipment to the current standards.

2 solutions for plant modernization Retrofit It is a intervention approach that provides the technical upgrade as well as the update of the installed equipment to the current standards. We have several years' experience in the development of new retrofit solutions for withdrawable circuit breakers for MV switchgears, that can be Siemens' or other manufacturer s. Thanks to our know-how we are able to realize technical solutions customized on our customers' requirements. All our equipments are tested with Type Tests in laboratories certified by SINAL to guarantee you the best solution for the market. Our solution includes To view the accredited tests go to the site and click on "Banche dati" Circuit breakers Trucks Functional wiring of operating mechanism Safety interlocks The new Siemens vacuum circuit breakers used for retrofits mantain or improve the performance of the existing circuit breakers. They are maintenance free and enviromental friendly The new trucks for withdrawability have the same dimensional and functional features, the same main sectioning contacts and the same earthing system as the existing circuit breakers. The wiring of the auxiliary circuit connectors and its features are identical to those of the existing circuit breakers. The new circuit breakers for the retrofit solutions are integrated with interlock devices identical to the ones installed in the existing circuit breakers.
