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
