This paper presents an ecosystem which aims at continuing the initiative of sustainable developments. This approach become more and more integrated in the regulation framework of the energy markets as the directives 2009/125/EC and 2014/25/EU. This ecosystem deals with increase the lifetime expectancies of medium voltage switchgear and controlgear exposed to special and severe service conditions. The association of sensors and algorithms enable to anticipate any early ageing. However a strong product design is still required, with a complete functional analysis anticipating the constraints met during the product lifecycle [1]. All of this allows a better expected lifespan coupled with a minimized environmental footprint.

The metal enclosed switchgear suitable for installation in MV / LV public distribution substations or private customer substations are key elements to ensure continuity of service in electricity supply. For that purpose, MV equipment shall comply with the requirements for insensitivity to harsh ambient environmental conditions found in the field. Based on modern technologies, new architectures of MV switchgear are able to meet these high requirements. Adapted operating modes allow to fulfill all usual expected functionalities duri ng operational life on site.
