Core

  • Rapid Grid Deployment: Full substation commissioning in under 24 hours for emergency restoration, grid maintenance bypass, and remote mining sites.
  • Multi-Axle Heavy-Duty Transport Chassis: Compatible with Sitrak/heavy tractor trucks, engineered for cross-country highway and unpaved terrain transport.
  • Hermetic SF6 Gas-Insulated Switchgear (GIS): Compact footprint with high impulse withstand and maintenance-free operation.
  • Integrated Microclimate SCADA Control Cabin: IP54 temperature-controlled operator room with protection relays, remote telemetry, and auxiliary AC/DC distribution.
  • Dual Cooling System: ONAN/ONAF high-efficiency radiators with automated low-noise forced air cooling for continuous full-load operation in ambient temperatures up to 50°C.
