SC(B)10 Series Resin-insulated Dry Type Transformer,cast resin transformer,dry-type transformerï¼?cast resin dry transformerï¼?step up dry transformer Dry Type Transformer Flame retardant, non-pollution, it can be installed directly in the load center. Maintenance-free, easy to be installed, low operating costs. Product Features Function Characteristics: Flame retardant, non-pollution, it can be installed directly in the load center. Maintenance-free, easy to be installed, low operating costs. The enclosure can be of Good moisture resistance, transformer can be put into operation without pre-drying under 100% humidity in the normal operation.  Low loss, light weight and small volume, low noise, good dissipation of heat, it can be 150% rated load operation under forced air cooling conditions.  Equipped with a complete temperature protection control system to provide reliable protection for the safe operation of transformers.  High reliability. The results of checking for the products that has been put into operation show that the reliability index has reached the international advanced level. Structural Characteristics: Foil Coil: Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine. The foil coil resolves problems such as large short-circuit stress, ampere turn unbalance, poor heat dissipation, existing the winding spiral angle and unsteady manual welding quality due to low voltage and large current coil. At the same time, the end of winding is treated with cast resin, solidification to make shape, moisture-proof and anti-fouling, the lead for copper bar is welded by argon arc welding automatically. Temperature Control Device: the transformer adopts BWDK series of signal thermometer. The temperature components are embedded in the upper half of the low-voltage coil, can detect and display the temperature of separate phase coil automatically and continuously, also have the functions of over-temperature alarm and trip.

Our dry-type transformers, also known as "dry transformers," are designed to provide efficient and reliable electrical power distribution. These transformers use air or resin as the cooling medium instead of traditional oil. This design minimizes the risk of environmental contamination and allows for safe operation in various settings. Key features of our dry-type transformers include: 1. **Safety and Environmental Friendliness:** As there is no oil involved, the risk of fire and environmental impact is significantly reduced. This makes them a safer and more environmentally friendly option. 2. **Versatility:** Dry-type transformers are suitable for a wide range of applications, including industrial facilities, commercial buildings, and residential areas. They can be customized to meet specific voltage and power requirements. 3. **Low Maintenance:** These transformers generally require lower maintenance compared to oil-filled transformers, resulting in cost savings over their lifecycle. 4. **Compact Design:** The absence of oil allows for a more compact and lightweight design, making them easier to install and suitable for locations with space constraints. 5. **Efficiency:** Our dry-type transformers are designed for high efficiency, ensuring minimal energy loss during power distribution. Whether for upgrading existing infrastructure or implementing new projects, our dry-type transformers are engineered to deliver optimal performance, reliability, and safety in diverse electrical applications.

Three-phase transformers are used to convert the available 3-phase mains voltage into any load voltage. To cater for the wide range of application areas involved,these transformers are essentially available in the same kinds of designs as the single-phase transformers, e.g. Three-phase dry-type transformer: separate winding version Three-phase series transformer: autotransformer winding version Three-phase safety, isolating, mains or insulating transformer: separate winding version In terms of how the 3 coils are connected, there are various options available and each of these provides the transformers with specific properties. The vector group code is composed of the following elements: The upper-case letter indicates the higher-voltage winding (the highest voltage in terms of operation). The lower-case letter indicates the lower-voltage winding. The brought-out neutral is indicated by means of N or n (depending on voltage level). â?¢ The distinctive number indicates the phase angle of the lower voltage in relation to the higher voltage (distinctive number multiplied by 30). The following winding connection options are available Delta: D, d Wye (or star): Y, y Zigzag: Z, z Example: Dyn5 Higher-voltage winding is delta-connected. Lower-voltage winding is star-connected with a brought-out neutral. The lower voltage lags behind the higher voltage by 150�° (5 x 30�°). Unless specifically requested otherwise, the transformers are configured with a double-star connection and a brought-out neutral (vector group Yyn0); for autotransformers the vector group is YNa0. Our three-phase transformer range includes all our standardised types for the 25 30.0 kVA performance range and a frequency of 50/60 Hz
