100000 kVA 110 kV Oil-Immersed power Transformer
In the scenario of a super-large power hub, the insufficient equipment carrying capacity and poor grid coordination are the industry pain points. During the procurement process, concerns about the high difficulty of customizing the equipment, weak compatibility with supporting equipment, and uncontrollable long-term operation and maintenance costs are your problems. We have launched the 100000KVA/110kV super-large high-voltage transformer, specifically designed for ultra-large-scale power transmission and hub power supply. It can be customized with high-end Oil Immersed Transformer specifications, compatible with the standard of Dry Type Transformer , and deeply linked with Box Type Substation , High And Low Voltage Switchgear . It is suitable for the grid connection of Combined Photovoltaic Substations with tens of thousands of kilowatts and national-level regional backbone power grid hubs, and can be paired with Electric Power Converter to achieve lossless power regulation, effectively solving the problems of unstable power supply for super-large loads, difficult customization and adaptation, and high operation and maintenance costs. It enables the backbone grid to operate safely, efficiently, and with low consumption, helping the purchaser build a stable and reliable super-large power transmission system and highlighting the value of core power supply equipment. Its core value lies in the carrying capacity of super-large loads and customized adaptation. Its applications cover national-level regional backbone grids, tens of thousands of kilowatt-level new energy bases, and super-heavy industrial core areas. It is a benchmark equipment for ultra-high voltage super-large distribution scenarios.

Design features
What the design is built around
Limitless capacity, loss-free transmission
The rated capacity reaches 100,000 KVA, breaking through the carrying limit of industry's super-large equipment. The anti-short-circuit and anti-grid shock resistance capabilities meet international standards. The power transmission loss is reduced by more than 18% compared to products of the same specification. It is suitable for the grid connection of Combined Photovoltaic Substations of tens of thousands of kilowatts and the high-power transmission of backbone power grids. When paired with the Electric Power Converter, it can achieve zero-loss regulation of power, ensuring the stability of power transmission.
Flexible customization and strong adaptability
Based on the requirements of national power grids and super-large new energy bases, the core parameters of Oil Immersed Transformer can be customized. It can perfectly integrate with Dry Type Transformer equipment and does not require the renovation of existing Box Type Substation and High and Low Voltage Switchgear systems. The customization cycle is short, the adaptability is high, and it significantly reduces the project implementation cost.
Tips
The installation must comply with the national standards for the installation of large-scale power equipment. Special attention should be paid to ensuring the bearing capacity of the foundation, intelligent heat dissipation, and lightning protection grounding. After customizing the Oil Immersed Transformer, the insulation oil quality, oil level, and sealing performance should be tested every six months. When operating in conjunction with Box Type Substation and Electric Power Converter, coordinated debugging should be carried out regularly to avoid the impact of grid fluctuations on the safety of equipment operation.
