Consists of a wide range of SF6 fully insulated compact, modular cubicles enabling the configuration of any electrical diagram in Medium Voltage Secondary Distribution networks up to 36kV.
This development brings a highly safe, reliable and user-friendly assembly, capable of withstanding all environmental conditions.
The performance of routine test across the various phases of the assembly procedure and the use of the most innovative manufacturing techniques assure the highest level of quality, as reflected in its ISO 9001 certification.
Features
- Protection and safety for people, goods and equipment against internal arc effects, proven through test performed in accordance with IEC 62271-200 standard.
- Capable of withstanding harsh environmental conditions (including flooding), long service life and absence of maintenance in live parts through full gas insulation and the use of screened connectors.
- Full modularity and future extensibility in both directions through compact connecting set. Flexibility to configure all types of diagram with the use of a connecting set.
- Smaller size and lower weight, making handling and installation easier.
- Safe and simple operation through the use of user-friendly driving mechanisms, including interlocks as standard.
- Extra safety: incorporation, a light voltage presence indicator; and optionally, an acoustic alarm preventing earthing.
- Accessories and live testing as an option.
- Horizontal fuse holders with front access, protected within a gas tank.
- Easy cable connection through front plug-in or screwable terminals.
