110kV Power Transformers
63000 kVA 110 kV Oil-Immersed power Transformer
In large-scale power distribution scenarios, the equipment carrying capacity is insufficient and the grid's interactivity is poor, which are the industry's pain points. During procurement, concerns include the inability to smoothly adapt the equipment to the grid, high difficulty in subsequent operation and maintenance, and delayed response in after-sales services. We have launched the 63000KVA/110kV ultra-large high-voltage transformer, which is specifically designed for ultra-large power transmission scenarios. It can be customized with a dedicated Oil Immersed Transformer specification, compatible with the standard of Dry Type Transformer , and efficiently interacts with Box Type Substation and High And Low Voltage Switchgear . It is suitable for Combined Photovoltaic Substations for ultra-large-scale grid connection and regional backbone power grids, and can be paired with Electric Power Converter to achieve precise power regulation, effectively solving problems such as unstable power supply in ultra-large power capacity, difficult grid adaptation, and cumbersome operation and maintenance. It enables efficient and low-consumption operation of the backbone grid and helps purchasers strengthen the core defense line of power transmission, reducing long-term operating costs. Its core value lies in the collaborative adaptation of ultra-large power capacity and the grid. Its applications cover regional backbone substations, ultra-large new energy bases, and ultra-heavy industrial clusters. It is the core core equipment for high-voltage backbone power distribution scenarios.

Design features
What the design is built around
Extra-large power capacity, strong grid adaptability
The rated capacity reaches 63000 KVA, exceeding the carrying limit of conventional equipment. It has outstanding resistance to short circuits and grid shocks, and can seamlessly connect to regional backbone grids. It meets the ultra-large-scale power transmission and grid connection requirements of Combined Photovoltaic Substations, operates in coordination with High And Low Voltage Switchgear and Electric Power Converter, and ensures stable grid voltage.
Customized adaptation, controllable operation and maintenance
Based on the requirements of the backbone power grid and large-scale industrial scenarios, specific parameters of Oil Immersed Transformers can be customized. It is compatible with the equipment of Dry Type Transformers. There is no need for large-scale renovations to the existing Box Type Substations. The operation and maintenance process is standardized, which can significantly reduce the difficulty of operation and maintenance and the manpower input.
Tips
The equipment installation must strictly comply with the installation standards for the backbone power grid, ensuring proper foundation load-bearing and ventilation and heat dissipation. After customizing the Oil Immersed Transformer, regular inspections of the insulating oil quality, oil level, and sealing performance are required. When operating in conjunction with the Box Type Substation and Electric Power Converter, regular grid linkage tests must be conducted to prevent load fluctuations from affecting the equipment operation.
