1. Product Definition & Core Functions

As a core device in the power system, the oil-immersed transformer uses insulating oil as a dual-purpose medium: it not only provides electrical insulation to ensure the isolation of key components such as windings and iron cores, but also acts as a cooling medium to transfer heat generated during operation to the outside for temperature control. Its core mission is to realize voltage transformation, long-distance transmission and terminal distribution of electrical energy, serving as a key hub for energy conversion and transmission in the power system.

2. Core Advantages

  • Mature Technology: Verified by long-term industrial practice, it features improved design and manufacturing processes, stable technical routes, and low failure rates.
  • High Reliability: Exhibits excellent stable operation performance in complex power grid environments, with superior anti-interference and anti-impact capabilities, adapting to long-term continuous working requirements.
  • Strong Overload Capacity: Equipped with sufficient thermal capacity reserve, it can withstand operating conditions exceeding the rated load for a short time, responding to power grid load fluctuations.
  • Long Service Life: The insulating oil and core components have excellent anti-aging performance, with a service life far exceeding similar equipment under normal maintenance, achieving high cost-effectiveness throughout the life cycle.

3. Application Fields

Benefiting from its technical advantages, it is widely used in various key fields, including:
  • Power Generation Side: Supporting power station units to achieve power boosting and transmission;
  • Transmission and Distribution Side: Backbone power grid networks, undertaking medium and high-voltage power transmission over long distances and regional distribution;
  • Industrial Field: Power supply supporting for large factories and heavy industry facilities;
  • Commercial Field: Power guarantee for urban distribution networks and large commercial complexes.

    Especially in medium and high voltage, large capacity application scenarios, it occupies an irreplaceable dominant position.

4. Operating Environment

Mainly suitable for outdoor operating environments, capable of adapting to temperature changes, rain, snow and other climatic conditions in the natural environment.
