High-performance 2500KVA 20KV Oil-immersed Transformer adaptable to various power supply needs

 

Currently, power engineering equipment generally suffers from high energy consumption and insufficient load stability, making it difficult for most traditional substations to meet the long-term continuous power supply requirements of factories and photovoltaic power plants. You often face challenges such as high equipment losses, low compatibility with supporting cabinets, and high difficulty in outdoor maintenance. To address these issues, we offer a 2500KVA 20KV oil-immersed transformer, combined with a dry-type transformer, box-type substation, High And Low Voltage Switchgear, Electric Power Converter, and Combined Photovoltaic Substations, providing integrated optimization from equipment selection to overall power distribution layout. This equipment uses a low-loss core and a sealed oil storage structure, stably supporting a 2500KVA rated capacity, adapting to 20KV high-voltage input conditions, and achieving compliant temperature rise control during long-term full-load operation. It is suitable for various scenarios such as industrial and mining areas, integrated photovoltaic power plants, and urban power distribution networks. After being put into use, the no-load loss of the new equipment is significantly reduced compared to older transformers. Combined with a complete set of high and low voltage Power Distribution Equipment, it can shorten the on-site installation cycle and reduce long-term operation and maintenance costs. It can also be linked with Combined Photovoltaic Substations and Electric Power Converters to achieve smooth switching between photovoltaic power generation and the municipal power grid, catering to both industrial production and new energy power generation needs. The equipment’s compatibility covers the vast majority of small and medium-sized power distribution projects.

 

Product Features

Low Consumption and Long-Term Operation: The 2500KVA 20KV Oil-immersed Transformer uses a high-permeability cold-rolled iron core. Its no-load and load losses strictly meet international Energy Efficiency standards, allowing for long-term continuous operation without frequent shutdowns for cooling. It is suitable for uninterrupted production plants and large-scale Combined Photovoltaic Substations providing continuous power supply.

Strong Compatibility: It can seamlessly match Box Type Substations and High and Low Voltage Switchgear. It also supports combination with Electric Power Converters and Dry Type Transformers to build hybrid power distribution systems. Project procurement does not require finding multiple suppliers to source matching equipment.

 

Practical Tips

1.When deploying this Oil-immersed Transformer outdoors, it is recommended to use a standard Box Type Substation for enclosure to isolate it from rain and dust, extending the lifespan of the insulating oil and coils.

2.If used in a photovoltaic project, before using it with an Electric Power Converter, verify the transformer output parameters to ensure they match the power supply system parameters of the Combined Photovoltaic Substations.

 

FAQ

Q: Is it suitable to use a 2500KVA 20KV Oil-immersed Transformer and a Dry Type Transformer together in the same distribution room?

A: Yes, they can be used together. Only a separate cooling area needs to be planned. The oil-immersed equipment is designed for high-capacity outdoor power supply, while the dry type equipment is suitable for indoor precision workshop power supply. Using a High And Low Voltage Switchgear can achieve zoned control of the circuit.

 

Q: What is the routine maintenance cycle for the equipment?

A: Under normal operating conditions, the insulating oil quality is tested every six months, and the coils and terminals are inspected annually. If deployed in dusty mining areas or open-air areas with Combined Photovoltaic Substations, the maintenance cycle is shortened to four months.

 

Q: What after-sales services are included after purchase?

A: A complete equipment testing report is included with the shipment. A complete set of Box Type Substation and switchgear installation drawings are provided. Remote technical guidance is provided after shipment. For large orders, engineers can be arranged for on-site commissioning. Core components enjoy the standard warranty period.

 

Q: Can this transformer be used with an Electric Power Converter for photovoltaic grid connection?

A: Fully compatible. The 20KV high-voltage specification is compatible with most photovoltaic conversion equipment. Combined with Combined Photovoltaic Substations, it can stably complete the entire process of power voltage boosting and grid connection.
