Oil-immersed Transformers Product Details: Delve into the comprehensive features that characterize our cutting-edge oil-immersed transformers, crafted for optimal power management.
Oil-immersed transformers, a pinnacle of engineering in power systems, are indispensable for voltage conversion and power transmission. Designed to meet high current and large capacity demands, they boast outstanding stability and reliability, making them the ideal choice for modern power grids.
Model Meaning: Unravel the significance behind our model designations, each tailored to ensure precision and clarity in identifying our transformative solutions.
Performance Characteristics: Explore the robust features that define our transformers, engineered for peak efficiency and enduring performance under the most demanding conditions.
1. Winding structure: Our high-voltage winding employs a multi-layer cylindrical design, featuring continuous or connecting continuous structures. This innovative design enhances shock distribution, minimizes magnetic leakage, and provides superior mechanical strength and resistance to short circuits.
The high-voltage winding adopts a multi-layer cylindrical structure, either continuous or connecting continuous, enhancing winding shock distribution, minimizing magnetic leakage, and ensuring high mechanical strength with strong short-circuit resistance.
2. Iron core design: Our transformers utilize premium cold-rolled grain-oriented silicon steel sheets. The full diagonal seam stacking method significantly reduces no-load loss and no-load current, optimizing efficiency.
Adoption of high-quality cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method drastically reduces no-load losses and no-load current, contributing to the transformer's supreme efficiency.
3. Fastening and anti-loosening: We employ advanced fastening techniques for both core and windings. Self-locking anti-loosening nuts secure high and low voltage leads, adopting a non-hanging center structure to endure transportation vibrations. All fasteners include nuts to prevent loosening over long-term operation.
The core and windings are secured with robust fastening measures, and high and low voltage leads are equipped with self-locking anti-loosening nuts, adopting a non-hanging center structure to withstand transportation vibrations. All fasteners come with locking nuts to ensure they remain secure during long-term use.
4. Vacuum processing: Our vacuum drying process for coils and cores, along with vacuum filtering and injection of transformer oil, effectively minimizes moisture within the transformer, ensuring optimal performance and longevity.
Coils and cores undergo vacuum drying, while transformer oil is meticulously vacuum filtered and injected to minimize internal moisture, ensuring exceptional performance and durability.
5. Oil tank design: The corrugated sheet oil tank features a breathing function, compensating for oil volume changes due to temperature fluctuations. It eliminates the need for an oil storage cabinet, reducing the transformer's height and enhancing its compact design.
