Oil-immersed Transformers Product Details:
Oil-immersed transformers are an indispensable asset in modern power systems, primarily facilitating voltage conversion and seamless power transmission. These transformers are meticulously engineered to cater to the demand for high current and large capacity in power systems, ensuring unmatched stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding utilizes a sophisticated multi-layer cylindrical structure, whether continuous or connecting continuous, enhancing shock distribution, minimizing magnetic leakage, and delivering superior mechanical strength and exceptional short-circuit resistance.

2. Iron core design:
Incorporating premium cold rolled grain oriented silicon steel sheets with a full diagonal seam stacking method, this design dramatically reduces no-load loss and curtails no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
Robust fastening mechanisms secure the core and windings, complemented by self-locking anti-loosening nuts on critical components like the high and low voltage leads, ensuring resilience against transport-induced vibrations. All fasteners are equipped with specialized nuts to maintain integrity during prolonged operation.

4. Vacuum processing:
Employing advanced vacuum techniques, coils and cores undergo meticulous drying processes, while transformer oil is expertly vacuum filtered and injected, significantly minimizing internal moisture to extend the transformer's lifespan.

5. Oil tank design:
The oil tank features innovative corrugated sheets with a breathing function to adeptly compensate for oil volume fluctuations due to temperature changes, eliminating the need for a traditional oil storage cabinet and subsequently reducing the transformer's overall height.

6. Other features:
This product boasts an elegant design, compact size, and minimal installation footprint, making it the quintessential maintenance-free solution for diverse applications.
Recognized for its versatility, this transformer finds widespread application in power plants, substations, industrial and mining enterprises, as well as rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: Ideally should range from -25°C to +40°C, accommodating a wide variety of environments.
Altitude limit: Operational reliability is ensured at altitudes not exceeding 1000m.
Air humidity: Designed to operate with no more than 90% relative humidity at a comfortable 25ºC, ensuring performance consistency.
Installation place: Choose locations devoid of corrosive gases and noticeable dirt to maximize product longevity and effectiveness.

 

Maintenance and upkeep:
Regular inspection: Routine checks of oil levels and insulation strength are essential. Address any issues promptly by replacing transformer oil to maintain peak performance.
Stable operation: Assure the transformer's enduring stability by preventing overloads, short circuits, and similar anomalies, guaranteeing optimal functionality.
Safety attention: Prioritize plant ventilation and fire prevention measures during installation, strictly adhering to technical specifications for flawless setup.
