Product characteristics

1. Winding structure:
The high-voltage winding is crafted using a sophisticated multi-layer cylindrical, continuous, or connecting continuous design. This innovation enhances the distribution of shocks throughout the winding, minimizes magnetic leakage, and provides exceptional mechanical strength with superior resistance to short-circuits.

2. Iron core design:
Our transformers leverage premium, cold-rolled, grain-oriented silicon steel sheets, meticulously arranged using a full diagonal seam stacking method. This not only reduces no-load loss but also significantly lowers no-load current.

3. Fastening and anti-loosening:
Robust fastening measures secure both the core and windings, incorporating self-locking anti-loosening nuts for high and low voltage leads. The innovative non-hanging center design withstands transportation vibrations, ensuring all fasteners remain secure during prolonged operation.

4. Vacuum processing:
Embrace advanced vacuum processing where coils and cores undergo vacuum drying, and transformer oil is filtered and injected in a vacuum. This meticulous process ensures minimal moisture, boosting transformer longevity and performance.

5. Oil tank design:
The oil tank features a corrugated sheet construction, equipped with a breathing function to adapt to oil volume changes from temperature variations. Designed without an oil storage cabinet, it effectively reduces the transformer's height, optimizing spatial efficiency.

6. Other features:
Boasting an elegant appearance and compact size, our transformers occupy minimal installation space, making them the ideal maintenance-free solution for modern power distribution needs.
Widely utilized across power plants, substations, industrial sectors, mining enterprises, and rural power grids, our transformers offer reliable solutions for varied power distribution systems.

 

Environment and Requirements:
Ambient temperature: Temperature needs to be ideally maintained between a range of -25°C to +40°C.
Altitude limit: Operational altitude should not exceed 1000 meters.
Air humidity: Relative humidity should be kept below 90% at a temperature of +25ºC.
Installation place: Select an installation area devoid of corrosive gases and noticeable dirt for optimal performance and longevity.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on oil levels and perform oil insulation strength tests. Should issues arise, promptly replace the transformer oil to ensure optimal functionality.
Stable operation: To maintain the stability of the transformer, prevent overloads and other anomalies such as short circuits.
Safety attention: Prior to installation, address ventilation and fire prevention issues in adherence with technical specifications to ensure safe and correct installation.
