Single-phase air-insulated medium voltage switchgear for railway power supply. UniGear R switchgear panels comply with all the standards and specifications for type tested high voltage switchgear with metal enclosure and which comply with IEC 60298 and 60694 standards.
Each cabinet is divided into different compartments dedicated to power equipment (busbar compartment, circuit breaker compartment and cable compartment) of auxiliary equipment (low voltage compartment, electrical boxes for connecting wires). The compartments are separated from each other by metal partitions. This design ensures the safety of personnel and equipment in the event of an internal arc fault.
As for the internal arc, type tests have been carried out according to IEC IEC 62271-200, the panel has been classified as LSC2B, IAC AFLR 25 kA, 1s (50 Hz) and IAC AFLR 40 kA, 0.5 s (16.7 Hz).
