Challenge
Within a project for a foundry in Poland, it was necessary to design a medium-voltage switchgear capable of handling high currents at a voltage level of 36 kV while simultaneously adapting to the limited installation space of the facility. The solution had to be clear in layout, service-accessible, and operationally safe in a demanding industrial environment.
Our Solution
IVEP supplied a steel, air-insulated medium-voltage switchgear of type MVSI-CB, designed as a segmented switchgear cabinet with two independent sections, arranged on two levels.
This concept enabled a clear separation of the incoming and outgoing parts of the distribution system and optimized the use of space within the technical hall.
Technical Specifications
- Rated voltage: 36 kV
- Rated current: 4,000 A
Switchgear Layout
The switchgear is divided into two functional sections:
- Section A – Incoming feeder (lower level)
- equipped with a disconnector
- Section B – Outgoing feeder (upper level)
- equipped with a circuit breaker and a disconnector
This arrangement ensures:
- clear operator orientation,
- logical structuring of the power path,
- safe access during maintenance and service operations.
Design and Construction
The switchgear features a steel structure and air insulation, providing a robust and proven solution for heavy industrial applications. The design focuses on mechanical strength, long-term stability, and reliable operation in the harsh environment of a foundry.
Result
- Functional and well-organized MV distribution solution for a foundry operation.
- Efficient use of space thanks to the two-level arrangement.
- Safe operation at high currents and a voltage level of 36 kV.
- The equipment was delivered on December 15, 2020, and successfully commissioned.
IVEP Value
This project demonstrates IVEP’s ability to design spatially and technically well-engineered medium-voltage solutions that respond not only to electrical parameters, but also to the operational layout and operator ergonomics.
