Miniver/c series is a set of prefabricated units, for internal use, in modular composition. these metal clad units have a metallic structure in lsc2B-pM class, air insulated and ready to be equipped with interrupting devices, vacuum insulated in withdrawable execution.
Principal features of the MINIVER / C
- Wide range of functional units
- Modular structure
- Internal arc version (if requested)
- Equipped with mechanical and electrical interlocks for maximum safety
- Compactness and optimization of the spaces
- Version with double outgoing in one cubicle available
- Easy installation and maintenance operation
- Certifications on type tests and acceptance tests available
With its features the Miniver/c range is ideal for offering solutions designed for being adapted to every type of applications, maintaining the continuity of service and safety for operators.
The flexibility of Medium voltage switchgears make them suitable for several installations in important electrical plants as:
- Industry (Cement, Petrochemical, Metallurgy, paper)
- Utilities and Distribution (Power plants, substations, cogeneration, new technology energy) • Marine (Passenger ships, Military ships, special ships, off shore)
- Transport (Railways, Underground transport, airports)
Reference standards
Rules the Miniver/c range is compliant with the following international rules:
- IEC 62271-1 – general rule for high voltage devices
- IEC 62271-200 – metal-enclosed switchgear and controlgear for rated voltage above 1kV and up to and including 52kV
