The next generation F-gas-free insulated switchgear (GIS) for 24 kV distribution networks
Aligned with our sustainability commitment, over the past decade we’ve been working on alternative options to eliminate F gases. We’ve identified the technical attributes that are most relevant for our main clients to select the most suitable alternative.
An F-gas-free solution based on five requirements
We have developed a state-of-the-art technology of integral gas insulation that is materialized in two new complete ranges of distribution switchgears. Engineered with zero changes in design parameters and operation, to achieve zero uncertainties in health, safety, reliability and performance.
Thus, we have the best alternative for the distribution grid to meet the following requirements:
1. Natural origin gas: industrial natural air
Natural air components. Industrially manufactured. Fully accessible.
Our innovative technology is based on a gas composed uniquely of natural components existing in the air, and industrially produced in a controlled and tested environment. A combination that contains no fluorine and that avoids the humidity present in the ambient air; while being easily reproducible and accessible as it is patent-free.
2. Minimum filling pressure
Well-known behavior. Proven tightness.
This requirement is based on more than 30 years of field experience in different site conditions, thus minimising uncertainties.
3. Easy operation & exploitation
Innovative load break switch. Circuit-breaker with proven technology.
The design of this solution features an already proven and tested switching and breaking technology in our well experienced SF6 switchgear ranges.
Regarding the switching functions, the core of the cubicle is an innovative load break switch. In particular, for circuit breaker protection functions the solution is based on experienced, vacuum breaking technology.
4. Compact dimensions
Similar footprint. Optimised dimensions.
Our new ranges maintain similar dimensions to the existing ones with SF6 insulation, thus allowing our customers the possibility of installing them in reduced spaces.
5. Digital native
Sensoring. Automation.
Our switchgears are designed to integrate sensors and remote monitoring as well as control and protection devices. Ready for automation to enhance management and digitalization of the electrical grid.
