Overview
Amorphous alloy dry-type transformers exhibit no-load losses that are 75% lower than those specified in Table 4 of GB/T 10228, and load losses that are 15% lower than those specified in the same table, making them state-of-the-art energy-efficient dry-type transformers.
Model and Meaning
Product Features
◆ Energy-efficient and environmentally friendly, with no-load losses 70% to 80% lower than those of conventional Class 10 dry-type transformers;
◆ Strong three-proof performance and high thermal-mechanical stability;
◆ Short payback period, with long-term benefits for customers.Operating Environment
◆ Conditions of Use;
◆ Ambient temperature;
◇ Maximum temperature +40℃;
◇ Minimum temperature: -25°C;
◇ Average temperature of the hottest month: +30°C;◇ Average annual temperature: +20°C;
◆ Altitude not exceeding 1000 m;
◆ The power supply voltage waveform is approximately sinusoidal;◆ The voltages of the three-phase power supply should be approximately symmetrical;
◆ The installation environment is free from obvious contamination;
◆ For indoor use.Structural Features
This product features a low-voltage foil-type winding made by copper foil winding, while the high-voltage winding is wound with H-class high-strength enameled wire. The entire assembly is encapsulated in an epoxy resin reinforced with glass fiber, providing excellent moisture resistance and crack resistance. The core is wound from amorphous alloy strip and adopts either a rectangular cross-section with a four-frame-five-column or a three-frame-three-column structure.
Product Uses
This product boasts low no-load losses, oil-free construction, flame-retardant self-extinguishing properties, moisture resistance, crack resistance, and maintenance-free operation. It can replace conventional dry-type transformers in any application where the latter are currently used, making it suitable for high-rise buildings, commercial centers, subways, airports, railway stations, industrial and mining enterprises, and power plants. It is particularly well suited for installation in environments with stringent fire-safety requirements, such as flammable and explosive settings.
