Discover the Oil-immersed Transformers - Where Engineering Meets Excellence:
Oil-immersed transformers stand as a cornerstone in power systems, delivering seamless voltage conversion and robust power transmission. Crafted to satisfy the high current and large capacity demands of modern power systems, they epitomize stability and cutting-edge reliability.

 

Model Meaning - Clarity in Specification:

 

Performance Characteristics - Delivering Unmatched Excellence:

1. Advanced Winding Structure:
Our high-voltage winding utilizes a sophisticated multi-layer cylindrical and continuous design, enhancing shock distribution, minimizing magnetic leakage, and ensuring superior mechanical strength with formidable short-circuit resistance.

2. Innovative Iron Core Design:
Employing high-quality cold-rolled grain-oriented silicon steel sheets, our design with a full diagonal seam stacking method significantly curtails no-load loss and diminishes no-load current.

3. Robust Fastening and Anti-Loosening Measures:
The core and windings are meticulously secured with advanced fastening techniques. Equipped with self-locking anti-loosening nuts, the structure is designed to endure transit vibrations. Every fastener features a locking nut ensuring unwavering stability during extended operation.

4. Superior Vacuum Processing:
Through vacuum drying of coils and cores, alongside vacuum-filtered oil injection, our process ensures minimal moisture presence within the transformer, preserving integrity.

5. State-of-the-Art Oil Tank Design:
Crafted from corrugated sheets with a breathing function, the oil tank accommodates oil volume changes due to temperature shifts without necessitating an oil storage cabinet, thereby reducing the transformer's height.

6. Distinctive Additional Features:
Featuring a sleek appearance and compact form, it's a maintenance-free solution that requires minimal installation space, making it a top choice for modern needs.
Our transformers are extensively employed in power plants, substations, industrial, mining enterprises, and rural power grids, enhancing power distribution systems worldwide.

 

Environment and Requirements - Ensuring Compatibility and Functionality:
Optimal Ambient Temperature Range: To ensure optimal performance, the ambient temperature should range from -25°C to +40°C.
Altitude Limitation: Operational altitude should not exceed 1000m to maintain efficiency.
Air Humidity Optimal Range: Air humidity should not surpass 90% relative humidity at +25ºC to uphold optimal performance.
Preferred Installation Location: Select an installation area that is free from corrosive gases and noticeable dirt to ensure longevity and reliability.

 

Maintenance and Upkeep - Keeping Your Systems Running Smoothly:
Regular and Thorough Inspection: Consistently monitor the oil level and test oil insulation strength. Address any discrepancies by promptly replacing the transformer oil.
Ensure Stable and Reliable Operation: To prevent issues like overloads or short circuits, maintaining stable transformer operation is crucial.
Safety and Precautionary Measures: Prior to installation, evaluate plant ventilation and fire prevention measures, adhering strictly to technical installation guidelines.
