The SCB12 is a three-phase dry-type distribution transformer with epoxy resin cast insulation that meets the 2nd-level energy efficiency standard. It is currently a mainstream energy-saving product on the market and is widely used in high-rise buildings, power stations, industrial and mining enterprises, and other places with high requirements for fire protection and safety. For purchase needs, please contact our factory.
The name SCB12 is a detailed blueprint of the transformer's advanced design and capabilities:
S - Three-Phase (San Xiang): Designed for high-power, three-phase electrical systems, making it the standard for industrial and commercial power distribution.
C - Cast Resin (Cheng Xing Gu Ti): The core and windings are vacuum-encapsulated in epoxy resin. This makes it fire-safe (F1 rating), environmentally friendly (no oil), highly resistant to moisture and contaminants, and ideal for indoor installations close to the load.
B - Foil Winding (Bo Rao): The low-voltage winding is made of a copper foil instead of traditional wire. This provides superior short-circuit strength, better heat dissipation, and higher mechanical stability.
12 - Energy Efficiency Level: This is the most critical feature. The "12" signifies compliance with China National Standard GB 20052-2020 Energy Efficiency Class 2. It represents a significant reduction in no-load and load losses compared to older models like SCB10 or SCB11, leading to substantial cost savings on your electricity bill.
Example: A model labeled SCB12-1000/10 is a Three-Phase, Cast Resin, Foil-Wound, Class 2 Efficient transformer with a 1000kVA capacity and a 10kV primary voltage.
Our SCB12 transformers are engineered for peak performance and reliability. Below is a summary of key specifications.
