Product Overview

  • Model Interpretation

    "SC(B)" is the identification code for epoxy resin cast dry-type transformers, with each letter corresponding to scenario-specific value: "S" represents a three-phase structure, which can meet the simultaneous power supply needs of multiple users; "C" refers to the cast insulation process, which improves the equipment’s insulation stability in environments with temperature fluctuations; "B" denotes low-voltage foil windings, which can reduce energy loss during operation. "12" serves as the design serial number, aligned with industry-specific technical specifications to ensure the equipment’s compatibility with existing power distribution systems. Manufacturer-customized suffixes like "NX3" mostly focus on scenario-based optimizations, such as narrow-body structural design (for small power distribution rooms) or adaptive protection for high-humidity environments. "Energy Efficiency Class 3" meets the requirements of national basic energy efficiency standards for distribution transformers, and its energy consumption level is suitable for scenarios where sensitivity to operating costs is low and only basic power supply needs to be met.
