S20-3150KVA oil immersed transformer

　　The S20-3150KVA oil-immersed transformer is a highly efficient, energy-saving, and reliable power equipment suitable for medium-to-large-scale industrial and power system applications. Below is an analysis from four dimensions: technical parameters, performance advantages, application scenarios, and market conditions.

　　I. Technical Parameters

　　Rated Capacity: 3150KVA, catering to medium-to-large-scale power demands.

　　Voltage Configuration: The high-voltage side supports 10kV and 35kV (customizable), while the low-voltage side is 0.4kV, meeting diverse grid voltage requirements.

　　Energy Efficiency Class: Class II energy efficiency, compliant with GB20052-2020 standards. No-load losses are reduced by 10%-30% compared to traditional models, and load losses are reduced by 20%, resulting in a 25% improvement in overall energy efficiency.

　　Insulation Class: Class H or higher, enabling operation in high-temperature environments and ensuring long-term stable performance.

　　Cooling Method: Standard natural cooling, with optional forced air cooling or water cooling systems to enhance overload capacity.

　　II. Performance Advantages

　　1. High Efficiency and Energy Savings

　　Utilizes high-grade oriented silicon steel sheets and oxygen-free copper conductors to reduce iron and copper losses.

　　Typical no-load loss value ≤1% of rated current, with significantly reduced load losses, minimizing energy waste.

　　2. Safety and Reliability

　　Fully enclosed structural design (protection class IP20/IP44), with strong short-circuit withstand capability.

　　Adaptable to harsh environments ranging from -25°C to 40°C, ensuring high operational stability.

　　3. Low Noise and Environmental Friendliness

　　Combines corrugated tank technology with low-noise processes, resulting in an operating noise level ≤55dB, reducing environmental impact.

　　4. Material and Process Optimization

　　Coil Material: Optional full copper or full aluminum construction. Full copper offers superior conductivity, while full aluminum provides lighter weight and corrosion resistance.

　　Core Technology: Five-step lap silicon steel sheets with burr-free shearing technology, further reducing no-load losses.

　　Tank Design: Corrugated tank or plate-type radiator, improving heat dissipation efficiency by 20%.

　　III. Application Scenarios

　　Industrial Sector: Suitable for high-load environments such as metallurgy, petrochemicals, and mining, meeting large-capacity power demands.

　　Power Systems: Ideal for grid distribution upgrades and renewable energy power station grid connections, enhancing grid energy efficiency and stability.

　　Commercial and Public Facilities: Ensures stable power supply for large shopping malls, hospitals, transportation hubs, and other critical facilities.

　　IV. Market Conditions

　　Price Range: Varies significantly based on manufacturer and configuration.

　　Standard Models: Approximately RMB 28,500/unit (e.g., Henan Chengde Electric).

　　High-End Models: Approximately RMB 345,000/unit (e.g., Shandong Jiaxing Electric).

　　Customized Models: For example, a 35kV high-voltage side model can cost up to RMB 175,000/unit (e.g., Shandong Xinrong).

　　Procurement Recommendations

　　Select Reputable Manufacturers: Prioritize ISO-certified enterprises to ensure products meet national standards.

　　Focus on After-Sales Service: Warranty periods typically exceed 20 years; confirm operational and maintenance support capabilities.

　　Customization Requirements: Supports customization of voltage class, protection class, cooling method, etc., to meet specific scenario needs.
