Product Details:
Oil-immersed transformers are indispensable tools in modern power systems, expertly engineered for efficient voltage transformation and power distribution. These transformers cater to high-current, large-capacity requirements, guaranteeing unparalleled stability and reliability in electrical networks.
Model Meaning:
Performance Characteristics:
1. Advanced Winding Structure:
The high-voltage winding incorporates a sophisticated multi-layer cylindrical, continuous, or interconnected structure. This innovation enhances shock distribution, minimizes magnetic leakage, and ensures exceptional mechanical strength and short-circuit resilience.
2. Superior Iron Core Design:
Crafted with premium cold-rolled, grain-oriented silicon steel sheets, using a full diagonal seam stacking method, this design efficiently reduces both no-load loss and no-load current, optimizing performance.
3. Robust Fastening and Anti-Loosening Features:
Our transformers boast meticulously fastened cores and windings, secured with self-locking anti-loosening nuts. This resilient structure withstands transportation vibrations, ensuring all fasteners remain secure during prolonged operations.
4. Precision Vacuum Processing:
Employing a meticulous vacuum drying process for coils and cores, alongside vacuum-filtered oil injection, this technique effectively minimizes moisture content, safeguarding transformer efficiency and longevity.
5. Innovative Oil Tank Design:
Featuring a corrugated sheet oil tank with innovative breathing capability, this design compensates for oil volume fluctuations due to temperature changes, eliminating the need for an oil storage cabinet and reducing overall transformer height.
6. Additional Distinctive Features:
With its sleek appearance, compact size, and minimal installation footprint, this transformer is the ultimate maintenance-free solution for modern power distribution needs.
Widely deployed in power plants, substations, industrial, mining enterprises, and rural power grids, these transformers are integral to contemporary power distribution systems.
Environmental Conditions and Installation Requirements:
Ideal Ambient Temperature: Optimal operation is ensured within a temperature range of -25°C to +40°C.
Elevation Constraints: Safe functionality is maintained at altitudes not exceeding 1000 meters.
Humidity Considerations: Relative humidity should remain below 90% at a temperature of +25ºC for optimal performance.
Preferred Installation Location: Select an environment devoid of corrosive gases and excessive dirt for best results.
Maintenance and Upkeep:
Routine Inspections: Regularly assess the oil level and conduct oil insulation strength tests, replacing transformer oil promptly if issues are detected.
Ensuring Stable Operation: Maintain stable transformer operation by preventing overloads, short circuits, and other abnormalities.
Critical Safety Considerations: Before installation, factor in ventilation and fire safety according to technical standards for proper installation.
