Detailed Insights into Oil-immersed Transformers:
Our oil-immersed transformers are essential components in modern power systems, expertly crafted for efficient voltage conversion and seamless power transmission. Tailored for high current and large capacity demands, these transformers boast exceptional stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical, continuous, or connecting continuous design, optimizing shock distribution, minimizing magnetic leakage, and enhancing mechanical strength and robust short-circuit resistance.

2. Iron core design:
Utilizing premium cold-rolled grain-oriented silicon steel sheets with an innovative full diagonal seam stacking method, this design significantly reduces no-load loss and no-load current.

3. Fastening and anti-loosening:
Each core and winding is secured with advanced fastening techniques. High and low voltage leads are equipped with self-locking anti-loosening nuts in a non-hanging structure, ensuring resilience against transport vibration. Fasteners come with protective nuts for enduring stability during prolonged use.

4. Vacuum processing:
Our vacuum drying for coils and cores, combined with vacuum-filtered oil injection, ensures minimal moisture infiltration, enhancing transformer longevity and performance.

5. Oil tank design:
Featuring a corrugated sheet design with breathing capability, our oil tank adapts to temperature-induced volume changes without an oil storage cabinet, reducing the transformer's height for a more compact solution.

6. Other features:
Aesthetically pleasing, compact, and space-efficient, our transformers are ideal for maintenance-free operations.
Our transformers find extensive application in power plants, substations, industrial and mining sectors, and rural power grids, enhancing efficacy within power distribution systems.

 

Environment and Requirements:
Ambient temperature: Optimal operation is expected within a temperature range of -25°C to +40°C.
Altitude limit: Recommended installation altitude should not exceed 1000m.
Air humidity: Should maintain less than 90% relative humidity at +25ºC for best performance.
Installation place: Choose a locale devoid of corrosive gases and visible contaminants for optimal installation.

 

Maintenance and upkeep:
Regular inspection: Routine checks of oil levels and insulation strength are crucial; any issues should prompt timely transformer oil replacement.
Stable operation: Ensure smooth transformer operation by averting overloads and short circuits, adhering to safety standards.
Safety attention: Prioritize ventilation and fire safety during installation, following technical specifications for accuracy.
