Product overview
2500kVA 20KV oil-immersed Power Transformer
For large industrial parks, mining enterprises and regional centralized power supply projects, high-load and long-term continuous power consumption have become a necessity. The bearing capacity and stability of equipment at the high-voltage end are particularly crucial. This 2500kVA 20KV Oil-immersed Transformer is specifically designed for 20KV high-voltage power transmission conditions and is widely used in large production bases, centralized power distribution stations, industrial and mining load centers, and large-scale new energy supporting projects, meeting the stable power demand for large areas and high bases. The entire machine can be combined and used with Box Type Substation . It can be coordinated with High And Low Voltage Switchgear to complete the overall planning of the high-voltage circuit.
The on-site power distribution layout is flexible. It can either independently serve as the main power supply equipment or be combined with Oil Immersed Transformer and Dry Type Transformer for networking. Relying on Electric Power Converter to stabilize power quality, it can smoothly connect with Combined Photovoltaic Substations , adapting to the modern power distribution mode of using traditional power grids and distributed energy together, and helping to upgrade and implement the power distribution system in the factory area.
Product Highlights It is manufactured strictly in accordance with the 20KV high-voltage insulation standards, with ample capacity for load storage. It can handle continuous full-load and short-term impact loads with ease. The voltage output is stable, and the overall power loss is controlled reasonably, making it suitable for continuous industrial operation throughout the year.
It adopts a fully sealed high-strength box structure, which is resistant to corrosion, dust, moisture and weathering. The overall rigidity is strong. Whether it is installed in an indoor distribution room for centralized placement or outdoors in a field station for open layout, it can operate stably for a long time and has a wide environmental adaptability.
Instructions for Use The installation site must ensure an open and ventilated environment, and reserve a standard heat dissipation spacing. Avoid a closed and hot environment where heat accumulates to ensure the heat dissipation efficiency and extend the equipment's service life. Daily maintenance mainly involves regular visual and sealing inspections. Focus on checking the weld seams and oil circuit conditions. The operation is simple, and the overall operation and maintenance burden is light.
Design features
What the design is built around
Low-loss magnetic core
Cold-rolled grain-oriented silicon steel and a stepped core reduce no-load loss and audible noise.
Sealed tank construction
Welded tank, quality-gasketed cover and pressure-tested seals reduce oil leakage risk in outdoor duty.
Thermal margin for hot climates
Cooling surfaces and oil volume are selected for high ambient temperature and cyclic loading.
System compatibility
MV terminals, cable boxes and LV bushings are matched to the switchgear and protection scheme.
