In the 220 kV large-scale hub power distribution scenarios, the lack of equipment load redundancy and weak customization adaptability are industry pain points. During procurement, concerns arise about the equipment not meeting the core hub requirements, delayed after-sales response, and high project adaptation costs are your problems. We have launched the 90000 kVA/220 kV super-large high-voltage transformer, focusing on ultra-large capacity redundancy and customized adaptation. It can be customized with high-end Oil Immersed Transformer specifications, compatible with Dry Type Transformer as a standard, and deeply adapted to Box Type Substation, High And Low Voltage Switchgear, achieving deep compatibility with Combined Photovoltaic Substations for grid connection of tens of thousands of kilowatts and national-level 220 kV backbone grid core hubs for power supply. When paired with Electric Power Converter, it can realize low-energy transmission and precise regulation of electricity, effectively solving the problems of insufficient redundancy in large-scale hub power supply, difficult customization adaptation, and weak after-sales support. It enables long-term stable and efficient operation of the backbone grid, helping purchasers reduce adaptation costs and strengthening the core defense line of national power hubs. Its core value lies in the ultra-large capacity redundancy and customized services, covering national 220 kV backbone grid core hubs, core areas of tens of thousands of kilowatts of new energy bases, and power supply hubs for heavy industrial clusters. It is the preferred equipment for 220 kV-level large-scale core power distribution scenarios.

2. Customized Adaptation, Thoughtful Service: Based on the core 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. There is no need for large-scale modification of the existing Box Type Substation and High/Low Voltage Switchgear systems. An exclusive customized service team is provided to follow up throughout the adaptation and commissioning process, reducing the difficulty of project implementation.

Tips:

The installation must strictly follow the 220 kV super-large power hub equipment installation specifications. Special attention should be paid to ensuring the bearing capacity of the foundation, efficient heat dissipation, and lightning protection and 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, load redundancy tests should be conducted regularly to ensure the ability to cope with sudden load fluctuations.

FAQ (Frequently Asked Questions):

Q1: Where does the load redundancy advantage of this transformer lie? Can it handle sudden load surges at the hub?

A1: The load redundancy is sufficient. The rated capacity of 90,000 KVA can easily handle the sudden load fluctuations at large-scale hub facilities. It has outstanding shock resistance and, when paired with the Electric Power Converter, can quickly regulate the power output, preventing sudden load changes from affecting the stability of power supply. It can be linked with Box Type Substation and High and Low Voltage Switchgear to adjust the load distribution in real time, and is suitable for the load fluctuation requirements after the grid connection of Combined Photovoltaic Substations.

Q2: Is the customization of Oil Immersed Transformer specifications a lengthy process? Can it be synchronized with the project schedule?

A2: The customization cycle is controllable. The regular customization cycle is 35-40 days. It can be flexibly adjusted according to the project progress. The dedicated customization team will provide continuous follow-up throughout the process, from parameter confirmation to production debugging, ensuring efficient connection throughout the entire process. The customization specifications can perfectly integrate with the Dry Type Transformer supporting equipment and the existing Box Type Substation, High and Low Voltage Switchgear systems, without the need for additional adaptation and time-consuming processes.

Q3: How is the product after-sales support? Can the core hub scenario failure handling be responded to promptly?

A3: The exclusive core hub after-sales guarantee system offers 4-year free warranty. During the warranty period, non-human faults are free for repair and replacement of core high-voltage components. A 24-hour emergency after-sales team is equipped. In core areas, on-site handling is provided within 24 hours; in remote areas, it is available within 48 hours. Customized technical guidance is provided for life, fully meeting the long-term operation requirements of national-level core hubs.
