Design features
What the design is built around
Ultra-large capacity redundancy, low consumption and stability
Rated capacity 100,000 KVA, voltage 220 KV. It has extremely strong load-bearing capacity and can withstand peak load impacts of national power grid hubs. Combined with the Electric Power Converter, it enables low-loss transmission of electrical energy and is compatible with Combined Photovoltaic Substations for large-scale grid connection. Its operational stability far exceeds industry standards.
Full-scenario compatibility and convenient operation and maintenance
Customizable Oil Immersed Transformer parameters can be designed according to the requirements of national power grids, perfectly compatible with Dry Type Transformer supporting equipment. No large-scale renovation of Box Type Substation, High and Low Voltage Switchgear is needed. Installation and commissioning are efficient, significantly reducing project implementation costs and operational difficulties.
Tips
The installation must strictly follow the 220KV super-large power equipment specifications. Special attention should be paid to ensuring the bearing capacity of the foundation, heat dissipation, and lightning protection. After customizing the Oil Immersed Transformer, the insulation oil quality and sealing performance should be tested quarterly. When operating in conjunction with the Box Type Substation and Electric Power Converter, regular load tests should be conducted to avoid overloading.
