In industrial production, commercial operations, and infrastructure projects, the 6kV–10kV 500kVA three-phase dry-type transformer is a widely used power device. Its price varies significantly based on technical configuration, materials, energy efficiency, and customization. This guide offers a comprehensive look at the pricing, influencing factors, and expert recommendations to help you make a cost-effective decision.
Price Range Overview
Basic Models: Priced between ¥40,000 – ¥60,000, these models feature full copper windings, epoxy resin insulation, IP00 protection, and natural air cooling. Suitable for general industrial distribution, commercial buildings, and municipal facilities.
High-Efficiency Models: Costing ¥65,000 – ¥100,000, they come with energy-saving low-loss technology, Level II energy efficiency or higher, and optional IP23 forced air cooling. Ideal for data centers, large hospitals, and urban rail systems.
Special Models: Ranging from ¥100,000 – ¥250,000, options include explosion-proof mining transformers with KA certification and amorphous alloy types with ultra-low no-load loss. Perfect for mines, tunnels, and renewable energy plants.
Main Factors Affecting Transformer Price
Material Selection: Full copper windings provide better conductivity and durability but increase costs by 30%–50% over aluminum. Amorphous alloy cores reduce no-load loss by up to 80%, but cost 50%+ more than silicon steel core types.
Energy Efficiency Grades: Level II transformers are 15%–20% more expensive than Level III (SCB10), while Level I can be up to double the cost due to technical complexity and premium materials.
Customization: Enhanced protection (IP23/IP44), forced cooling, smart monitoring, and special voltage design (e.g., 6kV/0.4kV) typically increase pricing by 10%–30%.
Brand & After-Sales Service: Well-known brands like CEEG or Shandong Huaheng may charge 10%–20% more for stable quality and nationwide support. Services such as on-site installation, commissioning, and 5-year warranty also add to the total cost.
Purchasing Advice
Clarify Priorities: Choose SCB10/SCB11 for balanced performance, SCB13/SCB14 for high-efficiency needs, and mining or amorphous types for harsh environments.
Track Raw Material Prices: Copper constitutes 40%–60% of cost—consider bulk purchases during price dips. Amorphous alloy prices depend on rare earth supply—check market stability beforehand.
Check Supplier Qualifications: Always request valid production licenses, type test reports, and ISO certificates. Prefer suppliers with proven project experience to ensure compliance and smooth delivery.
Negotiate Effectively: Large orders (10+ units) often get 5%–10% discounts. Clarify prepayment ratios and credit terms to optimize cash flow and cost management.
Choosing a 6kV–10kV 500kVA three-phase dry-type transformer involves evaluating multiple cost drivers and matching specifications to your project’s demands. By understanding the price structure and supplier landscape, you can secure the most cost-effective solution that meets both technical and operational standards.
