Product Features
Low Loss
Efficient energy savings through proper selection of core flux density and reduction of winding current density and structural losses.
Low Partial Discharge
Dust control, rounded electrode design, and vacuum oil filling effectively reduce partial discharge levels.
Temporary power supply
Provides all functions of a traditional substation with simple on-site installation—just connect the input and output cables for quick commissioning.
Easy transport
Compact structure with integrated vehicle transport design offers convenient transport, flexible use, and adaptation to diverse deployment scenarios.
Vibration- and shock-resistant
Reinforced, anti-loosening structural design of key components adapts to frequent jolting, sudden stops, and sharp turns for more stable operation
Quick grid connection
Reserved standard interfaces and wiring space enable more efficient on-site connection, shortening layout and commissioning time
