20kV Dry-type Distribution Transformer SC(B)12-NX3 Energy Efficiency Level 3 800kVA

• Product Type

  This equipment is an epoxy resin cast dry-type distribution transformer that uses air as the insulation and cooling medium. Its oil-free structure fundamentally eliminates the risks of equipment short circuits and environmental pollution caused by oil leakage—rather than merely reducing such risks—providing high safety guarantees for the long-term stable operation of the power distribution system.

  
  

• Model Interpretation

  "SC(B)" is the exclusive identifier for epoxy resin cast dry-type transformers, with each letter corresponding to practical usage advantages: "S" represents a three-phase design, suitable for centralized power supply to multiple users; "C" refers to the cast insulation process, which enhances the insulation stability of the equipment in environments with large temperature differences; "B" denotes low-voltage foil windings, which can reduce electromagnetic noise during operation. "12" serves as the design serial number, aligned with industry-specific technical specifications to ensure compatibility with existing power distribution equipment. Manufacturer-customized suffixes like "NX3" are mostly tailored designs for adapting to narrow installation spaces or high-humidity environments. "Energy Efficiency Class 3" meets the basic energy efficiency standards for national distribution transformers, and its energy consumption level is more suitable for scenarios where sensitivity to operating costs is low and only basic power supply needs to be met.

  
  

• Core Advantages & Application Scenarios

  The equipment has excellent moisture and dust resistance. Even in humid areas during the rainy season in southern China or dusty environments near small processing plants, it can maintain stable operation without the need to purchase additional moisture-proof or dust-proof enclosures, reducing initial investment. Its heat dissipation system is optimized for medium-low load conditions, eliminating the need for frequent cleaning or maintenance of heat dissipation components. While ensuring basic power supply for residents and small businesses, it maximizes the reduction of operation and maintenance costs. Therefore, it is more suitable for projects that prioritize basic safety and budget control and have no excessive energy efficiency requirements—such as small community convenience stores and power distribution renovation in old residential areas—rather than being limited to conventional scenarios.
