In modern power distribution networks, high-voltage substations demand total operational continuity, extreme thermal efficiency, and long-term durability. The 230kV Transformer engineered by Shandong Lukong Electric Equipment Co., Ltd. serves as a vital cornerstone for high-voltage transmission grids, regional substations, and mega-scale industrial power systems. Built with over three decades of advanced power equipment manufacturing heritage, our 230kV Transformers deliver maximum energy efficiency, exceptionally low partial discharge, and superior short-circuit withstand capabilities for global utility infra
structure.
To support seamless integration into diverse utility networks and international grid standards, every 230kV Transformer is designed and manufactured in strict compliance with top-tier electrical engineering protocols:

| Key Parameter | Technical Specification |
| Rated Primary Voltage | 230kV (Customizable up to 245kV max system voltage) |
| Secondary / Tertiary Voltage | 115kV, 69kV, 34.5kV, 13.8kV, or custom secondary ratings |
| Cooling Method | ONAN / ONAF / OFAF / OFWF |
| Voltage Regulation | On-Load Tap Changer (OLTC) / Off-Circuit Tap Changer (OCTC) |
| Partial Discharge Level | Low partial discharge (<10 pC at rated voltage) |
| Rated Frequency | 50 Hz / 60 Hz |
| Compliance Standards | IEC 60076, IEEE C57, ISO 9001, CE |
Every 230kV Transformer manufactured in our state-of-the-art facility uses high-permeability, cold-rolled grain-oriented (CRGO) silicon steel cores. Coupled with precision step-lap joint technology, our advanced magnetic circuit minimizes no-load losses, reduces excitation currents, and lowers operational noise, offering significant lifecycle cost savings for utility operators.
Voltage fluctuations on high-voltage transmission lines can jeopardize equipment downstream. Our 230kV oil-immersed power transformers come equipped with highly reliable On-Load Tap Changers (OLTC). This enables smooth, automatic, or remote voltage adjustments under full-load conditions without dropping power supply, maintaining a steady voltage profile across fluctuating load cycles.
Designed for heavy-duty industrial and grid applications, each 230kV Transformer features reinforced mechanical clamping structures, high-density insulating pressboard, and transposed copper winding conductors. This robust construction ensures maximum mechanical strength to withstand severe short-circuit electromagnetic forces and transient electrical surges.
Engineered to operate reliably in harsh ambient environments—including high-altitude regions, coastal areas, and extreme temperature zones—our transformer tanks undergo multi-layer anti-corrosion surface treatments. The hermetically sealed oil tank structure prevents moisture and oxygen ingress, slowing dielectric oil degradation and extending maintenance intervals.
Our 230kV Transformer series is widely deployed in high-capacity global power projects, serving as reliable equipment for:
Utility Transmission & Distribution Substations: Functioning as primary step-down transformers in regional high-voltage electrical grids.
Renewable Energy Grid Interconnection: Connecting utility-scale solar PV fields, onshore/offshore wind power stations, and battery energy storage systems (BESS) directly to the 230kV transmission grid.
Heavy Industrial & Mining Complexes: Delivering stable, high-volume electrical power to steel mills, chemical plants, aluminum smelters, and mining operations.
