Oil Immersed Grounding Transformer Features
- Industrial-Grade Grounding Protection：This Oil Immersed Grounding Transformer is a core model of industrial earthing transformers, designed to provide stable artificial neutral points for medium-voltage industrial grids. It efficiently diverts fault currents and limits transient overvoltages, meeting the rigorous grounding safety requirements of industrial earthing transformers in heavy-duty scenarios.
- Oil-Immersed Structure for Durability：The Oil Immersed Grounding Transformer adopts advanced oil-immersed insulation and heat dissipation technology, ensuring excellent thermal stability and insulation performance. Compared with other types of industrial earthing transformers, it boasts stronger resistance to harsh industrial environments such as high humidity and dust, enabling long-term reliable operation.
- Flexible Adaptation to Industrial Grids：As a versatile member of industrial earthing transformers, this Oil Immersed Grounding Transformer supports multiple grounding configurations (zig-zag, solid grounding, etc.). It seamlessly integrates into medium-voltage industrial power systems, adapting to diverse load characteristics and grid operation demands of industrial earthing transformers applications.
- Robust Construction & Low Maintenance：The Oil Immersed Grounding Transformer features a fully sealed tank and corrosion-resistant coating, minimizing oil aging and leakage risks. It requires minimal daily maintenance, aligning with the low-operation-cost needs of industrial earthing transformers in factories, substations, and other industrial facilities.
- Synergistic Operation with Industrial Systems：This Oil Immersed Grounding Transformer works in tandem with other industrial earthing transformers to form a multi-level grounding protection network. It enhances the overall stability of industrial power systems, effectively preventing equipment damage caused by grounding faults and safeguarding the safe operation of the entire production line.

Industrial earthing transformers electric's technology
- Core:The core of our Oil Immersed Grounding Transformer uses high magnetic conductivity grain-oriented cold-rolled silicon steel and a 45° five-step overlapping method, cutting down no-load loss and current—key for industrial earthing transformers performance. Simulation analysis controls vibration, and flexible core-coil/clamp connections reduce noise by 10–15dB, meeting the low-noise needs of industrial earthing transformers.
- LV Winding:The Oil Immersed Grounding Transformer’s LV windings adopt premium foil conductors or full copper wire, optimizing ampere-turn balance and reducing magnetic flux leakage to boost anti-short-circuit capability. Its excellent oil passage design enhances heat dissipation, lowering temperature rise and improving overload capacity for industrial earthing transformers in variable load scenarios.
- Tank:The Oil Immersed Grounding Transformer tank is made of high-quality steel, with phosphating rust removal and FVC anticorrosive coating to resist oil and chemical corrosion. It is suitable for harsh outdoor environments, matches the application demands of industrial earthing transformers, and features easy installation and maintenance-free operation.
