Product Overview
Basic Information
• Model Meaning: "S" stands for three-phase, "C" represents epoxy resin-cast dry-type transformers, "B" indicates that the coils are wound with copper foil materials, and "18" is the design sequence level code, representing its performance sequence level. The larger the number, the better the performance. NX1 means it meets the first-level energy efficiency standard.
• Capacity Range: It covers various specifications ranging from 30 KVA to 6300 KVA.
• Voltage Ratings: Common high-voltage side voltages include 6 kV, 10 kV, 11 kV, etc., and the low-voltage side voltage is mostly 0.4 kV.
Performance Features
• Energy-saving and High Efficiency: Both no-load loss and load loss are relatively low, meeting the first-level energy efficiency standard. Compared with the traditional SCB14 transformers, the no-load loss is reduced by 20% - 30%, and the load loss is also decreased, which can effectively save energy and reduce operating costs.
• Safe and Reliable: It adopts a dry-type structure and doesn't require oil injection, avoiding safety hazards such as leakage and fire that may occur in oil-immersed transformers. Its high-quality insulating materials and reliable protection systems also ensure the long-term stable operation of the equipment.
• Low Noise: With advanced noise reduction technology, it generates extremely low noise during operation, usually around 40 - 60 decibels, making it suitable for places with high requirements for noise.
• Convenient Maintenance: The dry-type transformer has a simple structure with few components, requiring little maintenance work. Moreover, there is no need to regularly replace the oil, greatly reducing the maintenance cost.
• Strong Adaptability: It has a wide load range, capable of withstanding from no-load to heavy load, from power frequency to impulse. It can operate stably under different environmental conditions, such as high temperature and humid environments.
