Product Overview
Rockwill’s 35kV oil-immersed earthing transformer is specially engineered to provide a reliable neutral grounding point in medium-voltage networks where direct grounding is not available. Designed with a zig-zag winding configuration, this 3-phase transformer ensures optimal zero-sequence impedance, effectively limiting ground fault currents and stabilizing transient overvoltages.
Its robust oil-immersed construction guarantees long-term insulation reliability and thermal performance in outdoor environments.
Key Features
Zig-Zag Winding: Enables controlled neutral grounding and effective zero-sequence current flow for protective device coordination.
High Insulation Performance: Complies with 35kV-class insulation levels and withstand voltage standards.
Efficient Core Design: Made of cold-rolled grain-oriented silicon steel to reduce core losses and no-load current.
Copper Windings: Oxygen-free copper ensures reduced winding losses and superior short-circuit resistance.
Fully Sealed Tank: Maintenance-free with anti-corrosion surface and integrated oil conservator (if required).
Standardized Manufacturing: Built in accordance with IEC 60076, IEEE, and customer-specific utility codes.
Typical Applications
Medium-voltage distribution systems (33/35kV class)
Renewable energy substations (solar, wind)
Isolated generator grounding systems
Utility and industrial MV feeders requiring neutral grounding
Protection system grounding via NGR (Neutral Grounding Resistor)
