Oil-immersed Transformers Product Details:
Our Oil-immersed transformers represent the pinnacle of power equipment technology, playing a crucial role in power systems for seamless voltage conversion and power transmission. Crafted for high current applications, these transformers offer unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding Structure:
Our high-voltage windings utilize a sophisticated multi-layer cylindrical, continuous, or connected continuous structure. This design enhances shock distribution, minimizes magnetic leakage, and delivers exceptional mechanical strength and robust short-circuit resistance, ensuring long-lasting performance.

2. Iron Core Design:
Employing premium-grade cold rolled grain oriented silicon steel, our transformers utilize a full diagonal seam stacking technique, significantly reducing no-load loss and minimizing no-load current, thereby boosting efficiency.

3. Fastening and Anti-Loosening:
Every core and winding is rigorously secured with advanced fastening techniques. High and low voltage leads feature self-locking anti-loosening nuts, allowing the structure to withstand transportation vibrations. Complete with fastening nuts, the system guarantees stability during long-term operations.

4. Vacuum Processing:
Through meticulous vacuum drying of coils and cores, alongside vacuum-filtered oil injection, our process ensures minimal moisture presence, enhancing the transformer's longevity and reliability.

5. Oil Tank Design:
Our innovative oil tank design incorporates corrugated sheets with a breathing function to adapt to temperature-induced volume changes. The absence of an oil storage cabinet reduces the transformer's height, optimizing space.

6. Other Features:
Boasting an elegant appearance and compact design, these transformers require minimal installation space and are ideal for maintenance-free operation, making them a preferred choice for diverse applications.
These transformers are perfectly suited for deployment in power plants, substations, industrial and mining enterprises, as well as rural power grids, ensuring superior performance in power distribution systems.

 

Environment and Requirements:
Ambient Temperature: Typically required to range between -25°C to +40°C, ensuring optimal performance across diverse climates.
Altitude Limit: Designed for installations not exceeding 1000 meters above sea level, ensuring adaptability to various geographic conditions.
Air Humidity: Ensures reliable operation with relative humidity not surpassing 90% at +25ºC, enhancing durability.
Installation Place: Select an area devoid of corrosive gases and obvious contamination to ensure longevity and optimal performance of the transformer.

 

Maintenance and Upkeep:
Regular Inspection: It's crucial to frequently monitor the oil level and conduct oil insulation strength tests. Promptly replace the transformer oil if any issues are detected to maintain peak performance.
Stable Operation: Implement practices to ensure the transformer's stable operation, preventing overloads, short circuits, and other potential anomalies.
Safety Attention: Prioritize factors such as plant ventilation and fire prevention during installation, adhering to technical specifications for safe and correct setup.
