Product Overview
As a key high capacity power distribution equipment in the 10kV/35kV power grid system, the 5000kVA oil immersed power transformer plays a crucial role in voltage conversion, power transmission, and efficient power distribution. With its core advantages of ultra large capacity output, high efficiency power conversion, and stable operation around the clock, the step up down transformer can be precisely adapted to various high load power consumption scenarios, including large industrial and mining enterprises, new energy power plants such as photovoltaic/wind power/energy storage, urban core power distribution nodes, large commercial complexes, data centers, and key infrastructure projects. It provides safe, continuous, and reliable power supply for large scale power demand and can flexibly cope with various complex power conditions.
5000kVA power transformer is a core piece of high capacity power distribution equipment in the 10kV/35kV power grid. Besides its fundamental functions of voltage conversion, power transmission, and distribution, its on load tap changing model (SZ series) offers significant advantages. This model supports a voltage regulation range of ±3×2.5%, allowing for flexible adjustment of the output voltage without shutdown while the transformer is operating under load. This effectively addresses complex conditions such as grid voltage fluctuations and load changes, ensuring the stability of the power supply voltage.

Oil Immersed Transformer FAQ
1. What is the short circuit withstand capability of your transformers?
Our designs meet IEC standards. Typical short circuit impedance is 4‑8%, and units pass certified short circuit tests to ensure no winding displacement or damage.
2. Do you provide remote monitoring features?
Yes. We can integrate oil temperature, winding temperature, oil level, and DGA sensors with remote communication (4G, RS485, or Ethernet) for smart grid applications.
3. What is the typical lead time for a custom oil immersed transformer?
Standard designs: 4‑6 weeks. Custom units (special voltage, impedance, or accessories): 8‑12 weeks, depending on factory load and complexity.
