introduction of SG(B)12~18 dry type transformer
GNEE TRANSFORMER supplies SG(B)12~18 non-encapsulated H-class dry type transformer.
SGB series non-encapsulated H-class dry-type transformer adopts the special process technology of (Germany) MORA dry-type transformer, so that the product can fully meet the requirements of fireproof, waterproof and environmental protection. It is an ideal product for power distribution system, and is widely used in subways, ships, mines, chemical industries, power enterprises and densely populated buildings and other occasions with special require- ments for safety and fire protection.
Features:
- High – Temperature Resistance
The H – class insulation enables these transformers to operate in high – temperature environments without significant degradation of performance. This is crucial in applications where ambient temperatures may be elevated, such as in industrial settings with large amounts of heat – generating equipment or in areas with hot climates. For example, in a steel mill, where the operating temperature can be quite high, the SG(B) H – class dry transformer can maintain stable power conversion.
- Fire – Resistant and Environmentally Friendly
The use of non – combustible H – class insulation materials makes these transformers highly fire – resistant. This reduces the risk of fire hazards in case of electrical malfunctions, enhancing safety in various installations. Additionally, since they do not use oil as a coolant like some traditional transformers, there is no risk of oil leakage, which is more environmentally friendly. They are suitable for installation in areas where environmental protection is a priority, such as near water bodies or in densely populated urban areas.
- Low Noise Operation
SG(B) packageless H – class dry transformers are designed to operate with low noise levels. The optimized core design and winding technology reduce the mechanical vibrations and electromagnetic noises that are common in transformers. This makes them ideal for applications where noise pollution needs to be minimized, such as in hospitals, schools, and residential areas.
- High Efficiency
With advanced design and high – quality materials, these transformers achieve high energy efficiency. The low – loss core and well – designed windings result in reduced power losses during operation. This not only saves energy but also helps in reducing operating costs for users. In commercial buildings with large power demands, the high – efficiency operation of SG(B) H – class dry transformers can lead to significant savings in electricity bills over time.
