Medium Voltage electrical Cabinets
Metal enclosed MV cabinets are compact modular structures made with top quality metal sheets with a thickness of not less than 2 mm painted with a RAL 7035 colour with a textured surface.
The fundamental prerogatives of this type of cabinet are:
- Operator safety
- Modularity of the system that allows the realization of any system solution
- Easy operation thanks too HMI, synoptic graphic display
- Use of circuit breakers, insulated in vacuum or in SF6, which allow easy operation, do not require maintenance of the power parts and reduce the maintenance of the control parts
The supply of the cabinets is always accompanied, both in paper and digital format, by the following documentation:
- Final drawing
- Test report
- Declaration of conformity with the CEI EN standards in force
- Technical documentation relating to the equipment used
In addition, reports relating to peak withstand tests, short-time currents on the protection circuit and dielectric tests will be available.
