ZN Type Zigzag Neutral Earthing Transformer 10kV 35kV
Scope of Application
Photovoltaic Step-Up Stations
Used to provide a neutral grounding path for inverter-side faults, limiting fault current and enabling rapid protection isolation.
Package Substations
Integrated into compact prefabricated units to establish a stable neutral ground while suppressing harmonics and transient overvoltages in outdoor environments.
Industrial Power Supply Systems
Employed in resistor- or reactor-grounded systems to control single-phase fault current amplitude and ensure reliable relay protection for continuous production operations.
Product Description
-
1 - We utilize a Zn (zigzag) winding configuration, which offers high zero-sequence impedance and low positive-sequence impedance, ensuring no disruption to the system's normal power supply.
-
2 - Our design achieves excellent performance with low losses, minimal temperature rise, and low operating noise.
-
3 - We employ an enhanced insulation class to ensure high resistance to lightning strikes and switching overvoltages, making the transformers suitable for PV box-type booster stations and prefabricated substations.
-
4 - Both oil-immersed and dry-type designs are available, with protection ratings customizable to specific requirements.
