110kV Power Transformers
80000 kVA 110 kV Oil-Immersed power Transformer
In the scenario of ultra-large-scale power transmission, the insufficient load-bearing capacity of equipment and the high power transmission loss are industry pain points. When purchasing, there is concern about the incompatibility of the equipment with various supporting equipment and the difficulty in troubleshooting in the future. We have launched the 80000KVA/110kV ultra-large high-voltage transformer, focusing on the core requirements of ultra-large-scale power transmission. We can customize the specific Oil Immersed Transformer specifications, which are compatible with the Dry Type Transformer supporting system. It can precisely interact with Box Type Substation , High And Low Voltage Switchgear , and is suitable for the grid connection of Combined Photovoltaic Substations and regional backbone power grids with a capacity of hundreds of millions of kilowatts. When paired with an Electric Power Converter , it can achieve efficient power regulation and effectively solve problems such as unstable power supply for ultra-large loads, high transmission loss, and difficult equipment compatibility. It ensures the long-term safe and efficient operation of the backbone grid and helps purchasers reduce overall operating costs, strengthening the core barrier of ultra-large-scale power transmission. Its core value lies in the ability to carry ultra-large loads and adapt to multiple scenarios. It covers regional backbone grid hubs, ultra-large new energy bases, and extremely heavy industrial clusters. It is the core supporting equipment for ultra-high voltage and ultra-large capacity distribution scenarios.

Design features
What the design is built around
Overcapacity bearing, low consumption, high efficiency
With a rated capacity of 80000KVA, it breaks through the bottleneck of ultra-large equipment bearing capacity, has a far superior anti-short-circuit and anti-load shock capability compared to industry standards, and has an electricity transmission loss of more than 15% lower than products of the same specification. It is compatible with the grid connection requirements of Combined Photovoltaic Substations for ultra-large-scale grid connection and high-power transmission in the backbone grid. When paired with an Electric Power Converter, it can further improve the efficiency of power utilization.
Compatibility with multiple devices, easy troubleshooting
Without the need for large-scale renovation of the existing distribution system, it can be seamlessly adapted with Box Type Substation and High And Low Voltage Switchgear. It is compatible with the supporting standards of Oil Immersed Transformer and Dry Type Transformer. The equipment is equipped with an intelligent monitoring module, which can provide real-time feedback on the operating status, significantly reducing the difficulty of troubleshooting in the future and reducing the labor input for maintenance.
Tips
Installation must strictly follow the installation specifications for ultra-large power equipment to ensure proper foundation bearing, ventilation and heat dissipation, and lightning protection. After customizing the Oil Immersed Transformer, regular inspections of the insulation oil quality, oil level, and sealing conditions are required. When operating in conjunction with Box Type Substation and Electric Power Converter, the intelligent monitoring module needs to be regularly calibrated to avoid the impact on equipment lifespan due to sudden load changes.
