Description
Product Technical Advantages
1. Core Manufacturing Process: Utilizes high-quality cold-rolled silicon steel sheets, combined with advanced lamination techniques and binding processes. The core structure is tightly integrated, significantly reducing no-load losses, no-load current, and eddy current losses.
2. High-Quality Winding Design: Constructed using premium oxygen-free copper wire or copper foil. Employs advanced coil structures—such as continuous or multi-layer cylindrical designs—to ensure superior conductivity and thermal stability, while significantly enhancing short-circuit withstand capability and mechanical strength, and balancing electromagnetic force distribution.
3. “Dual-Low” Design (Low Loss / Low Noise): The product strictly complies with the latest energy efficiency standards and national regulations. By optimizing the core structure and cooling system, it achieves low energy loss and operational cost savings while simultaneously significantly reducing operational noise levels.
4. Comprehensive Mechanical Safety: Manufacturing processes ensure the active part (core and coils) is securely positioned. It effectively withstands vibrations and shocks during transportation and long-term operation, thereby safeguarding internal structural stability and extending the product’s service life.
5. Intelligent Voltage Regulation: Offers an optional on-load voltage regulation (OLTC) feature. This allows for automatic or manual adjustment of voltage output without interrupting power supply, perfectly meeting the stringent voltage quality requirements necessitated by fluctuations in grid load.
