Product Overview-
Product TypeThis equipment is an epoxy resin cast dry-type distribution transformer, featuring air-based insulation and cooling systems. Unlike traditional oil-immersed transformers, its oil-free structure rules out oil leakage hazards entirely—this design upgrade directly elevates operational safety, especially in enclosed spaces.
-
Model Interpretation"SC(B)" denotes epoxy resin cast dry-type transformers, where each letter reflects key performance traits: "S" = three-phase operation (for stable power supply), "C" = cast insulation (enhancing durability), "B" = low-voltage foil winding (improving current-carrying capacity). "12" serves as the design serial number, aligned with industry-specific technical norms to ensure consistent quality. "NX3" is a manufacturer-customized suffix, typically tied to structural refinements (e.g., space-saving designs) or scenario-specific tweaks (e.g., humidity adaptation). "Energy Efficiency Class 3" meets the minimum energy efficiency criteria in national distribution transformer standards, delivering balanced power usage for basic needs.
-
Core Advantages & Application ScenariosBoasting reliable moisture and dust resistance, it performs well in harsh environments like damp workshops or dusty warehouses—no extra protective enclosures are needed. It’s also suitable for direct installation in indoor distribution rooms, such as those in shopping malls or residential underground garages. Its heat dissipation system is optimized for medium-low load operations, striking a great balance between performance and cost. This makes it a top pick for projects that prioritize basic safety and budget control over high energy efficiency, such as small retail outlets or standard residential community power distribution systems.
Target Market
