Non-Crystalline Alloy Transformer Purchase Guide

　　I. Core Advantages

　　Non-crystalline alloy transformers are primarily characterized by their ultra-low no-load losses, which can be reduced by 60%-80% compared to traditional silicon steel transformers. They are particularly well-suited for scenarios with a load factor below 40%, such as rural power grids and renewable energy grid connections. Their iron cores are made of non-crystalline alloy strips, which feature high magnetic permeability and low coercivity, effectively minimizing iron losses and meeting China's first-class energy efficiency standards.

　　II. Price Range and Influencing Factors

　　Dry-Type Transformers

　　Small (below 10kVA): Several thousand to tens of thousands yuan

　　Medium (200kVA-1000kVA): Tens of thousands to over a hundred thousand yuan

　　Large (above 1000kVA): Over a hundred thousand yuan, requiring custom quotes

　　Examples: The SCBH15-50 dry-type non-crystalline alloy transformer (200kVA) costs approximately 23,000 yuan; the SCBH15-2000kVA model costs around 130,000 yuan.

　　Oil-Immersed Transformers

　　Small to Medium (100kVA-1600kVA): 50,000 to 150,000 yuan

　　Large (above 2000kVA): 100,000 to 300,000 yuan

　　Examples: The SH15-M-1000/10 oil-immersed transformer costs approximately 103,000 yuan; the S11-M-1250/10 model costs around 83,000 yuan.

　　Factors Influencing Prices

　　Brand: Leading brands like TBEA and Jinpan Technology command higher prices but offer mature technology; regional suppliers such as Shandong Huaheng provide better cost-effectiveness.

　　Energy Efficiency Rating: Products with first-class energy efficiency have a premium of about 10%-15%, but offer significant long-term energy savings.

　　Customization Requirements: Special environments (e.g., high temperatures, corrosion) or functions (e.g., intelligent monitoring, explosion-proofing) incur additional costs.

　　III. Selection Recommendations

　　Select by Application Scenario

　　Indoor/Dry Environments: Prioritize dry-type transformers (e.g., SCBH15 series) for their maintenance-free operation and high safety.

　　Outdoor/High-Humidity Environments: Choose oil-immersed transformers (e.g., SH15 series) for their superior heat dissipation and sealing performance.

　　Renewable Energy Sector: Recommend non-crystalline alloy dry-type transformers for their compatibility with the fluctuating loads of photovoltaic and wind power systems.

　　Match Capacity to Demand

　　Commercial Buildings/Industrial Parks: 100kVA-1600kVA 10kV transformers, such as the Jiangsu Hong'an SCBH15 series.

　　Large-Scale Industries/Power Grid Projects: 2000kVA and above 35kV transformers, such as the TBEA SCB18 series.

　　Rural Power Grids/Distributed Energy: Small-capacity transformers below 200kVA to reduce costs.

　　Key Parameter Comparisons

　　Load Loss: Prioritize products with load losses below the industry average (e.g., the Noah SCBH15-800 model has a load loss of 6960W).

　　No-Load Loss: Non-crystalline alloy transformers should have no-load losses at least 60% lower than those of silicon steel transformers.

　　Insulation Class: Opt for F-class or H-class insulation to withstand high-temperature environments.

　　IV. Supplier Recommendations

　　Industry Leaders

　　TBEA: Offers solutions across all voltage levels, with leading technology in 35kV large-capacity transformers and a nationwide service network.

　　Jinpan Technology: A core global supplier for renewable energy, with a high market share in photovoltaic and wind power transformers and products exported to Europe and the Americas.

　　Regionally Advantaged Suppliers

　　Shandong Huaheng: With an annual production capacity of 1.5 million KVA, supports customization for 6KV-35KV voltage levels and offers a comprehensive range of S11/S13/S20 series.

　　Henan Taixin Electric: Provides S11/S13 energy-efficient transformers and offers 24-hour on-site services, suitable for the Central Plains region.

　　Specialized Transformer Suppliers

　　Jiangsu Juli Power: Focuses on 35kV non-crystalline alloy transformers and supports non-standard customization, such as the SH15 non-crystalline alloy transformer.

　　Qingdao Qingdian Electric: Offers sealed oil-immersed transformers and supports large-scale transformer customization, such as the S11-2000kVA model.

　　V. Procurement Considerations

　　Technical Solution Verification

　　Require suppliers to provide detailed solutions, including iron core material (non-crystalline alloy strips), winding structure (double/triple winding), and cooling method (oil-immersed natural cooling/forced air cooling).

　　Prioritize products certified by international organizations such as KEMA and CUL to avoid grid connection failures.

　　Cost and Delivery

　　Bulk Purchases: Negotiate prices with small to medium-sized suppliers; quotes for 10kV/630kVA transformers can be as low as 85% of the industry average.

　　Urgent Deliveries: Choose suppliers in the East China region (e.g., Shanghai Chuanyong) for short logistics radii and 48-hour delivery capabilities.

　　Framework Agreements: Sign annual agreements with suppliers like Shunte and Jinpan to hedge against price fluctuations.

　　After-Sales Support

　　Confirm whether suppliers offer full lifecycle services, such as transformer condition monitoring and remote fault diagnosis.

　　Require suppliers to have regional warehouses nationwide to ensure core component replacement cycles (e.g., temperature controllers, fans) of no more than 24 hours.

　　VI. Risk Mitigation

　　Low-Price Traps: Avoid suppliers that reduce costs by thinning silicon steel sheets or lowering insulation levels, as these products may have no-load losses exceeding standards by over 20%. Request type test reports to verify parameters.

　　Service Gaps: Small to medium-sized suppliers may lack high-voltage testing equipment, leading to return-to-factory repair cycles of 15-30 days. Prioritize suppliers with complete testing capabilities (e.g., Henan Taixin Electric).

　　Trade-In Programs: Utilize supplier recycling policies to dispose of old equipment; some manufacturers offer 10%-15% subsidies for replacements, reducing upgrade costs.
