2026 Mainstream Price Range for 1250kVA Dry-Type Transformers

Current market prices are influenced by core factors such as materials, manufacturing processes, and energy efficiency, showing a clear three-tiered distribution. The following prices are direct factory prices (excluding installation and transportation), avoiding intermediary markups, and are therefore more valuable for reference:

Basic Entry-Level Tier (45,000 RMB - 80,000 RMB): Short-Term Emergency Option

Products in this range mainly use aluminum windings or copper-aluminum mixed structures, with the core model being the SCB10 series, only meeting basic power distribution needs. The manufacturing process uses conventional casting, with an IP20 protection rating, and no additional temperature control or noise reduction design. It is suitable for temporary power distribution in small industrial and mining enterprises, remote outdoor low-load scenarios, and projects with extremely limited budgets. From a manufacturer's perspective: some small manufacturers may quote as low as 45,000 RMB, but this may involve using ordinary silicon steel sheets for the core and cutting corners on the windings. Although the initial cost is low, the annual losses are high, and the lifespan is only 8-10 years.  It is not recommended for long-term fixed-scenario use. 

Mainstream Practical Range (80,000-150,000 RMB): Preferred for Industrial and Commercial Use

This is the most in-demand market segment and our factory's main supply range.  All products feature all-copper windings, covering SCB11, SCB12, and SCB13 series models, complying with the GB 20052-2024 national standard Level 1 energy efficiency. The manufacturing process utilizes vacuum epoxy resin casting (penetration rate ≥99%), equipped with a fan temperature control system, achieving an IP30 protection rating, and a no-load noise level of ≤55dB. These models are suitable for most industrial parks, commercial complexes, and general data centers.  Specific pricing reference: SCB11-1250kVA/10kV all-copper model: 89,000-100,000 RMB; upgraded SCB13 series (30% lower no-load loss than SCB11): 97,000-130,000 RMB; models using our factory's 30Q130 high-permeability silicon steel sheets are priced at approximately 105,000 RMB, offering excellent value for money.

High-End Custom Range (150,000-250,000 RMB): Specialized for Specific Scenarios

Designed for high-demand scenarios, the core advantages lie in stability, intelligence, and environmental adaptability. The mining-specific KSG series meets explosion-proof, moisture-proof, heat-resistant, and salt spray resistance requirements, priced at 150,000-180,000 RMB; data center-specific models utilize nano-modified resin technology and are equipped with IoT monitoring modules (real-time monitoring of temperature rise and loss), priced at 180,000-220,000 RMB; the SCBH15 series with amorphous alloy cores, due to extremely low no-load loss, can be priced at around 250,000 RMB, suitable for high-end projects with strict energy consumption control requirements. These products require 1-2 months for customization, and the manufacturer will work closely with clients to optimize solutions based on specific scenario needs.

Manufacturer's Secrets: 5 Core Factors Affecting Price (Avoiding Hidden Costs)

Core Material: The long-term cost difference between all-copper and aluminum windings

The winding material is a key price differentiator. All-copper windings cost 15,000-30,000 RMB more than aluminum windings, resulting in a 15%-30% higher price. However, from an application perspective, the advantages of all-copper extend far beyond this. Pure copper offers 60% higher conductivity than aluminum, reducing load losses by 15%-20%, and boasts high mechanical strength and corrosion resistance, resulting in a lifespan of 25-30 years.  While aluminum windings are initially cheaper, they are prone to oxidation and rapid temperature rise, leading to higher annual maintenance costs.  Based on a 30-year lifespan, the total cost of ownership is approximately 180,000 RMB higher than that of a pure copper model. All our mid-to-high-end models come standard with pure copper windings, and we can provide material testing reports for traceability.

Energy Efficiency Rating: A Cost-Effective Choice Driven by Policy

From 2026 onwards, newly commissioned transformers must meet Level 1 energy efficiency standards, leading to the gradual phasing out of the high-energy-consuming SCB10 series, which is the core reason for its lower price. The SCB13 and SCB14 series, with lower no-load losses, are priced 10%-15% higher than the SCB11, but they qualify for a 70% VAT refund policy, making them more cost-effective in the long run due to energy savings. Furthermore, voltage regulation and cooling methods also affect the price: on-load voltage regulation models are 15,000-20,000 RMB more expensive than off-load voltage regulation models, and forced air cooling is 10,000-15,000 RMB more expensive than natural air cooling. Selection should be based on grid fluctuations and load conditions.

Process and Protection: Details Determine Lifespan

The manufacturing process directly impacts equipment stability. Vacuum casting is 20,000-30,000 RMB more expensive than conventional casting, but its high epoxy resin penetration effectively resists humid environments, preventing insulation failures in areas like southern China and coastal regions. Upgrading the protection level from IP20 to IP40 requires adding a sealed dustproof structure, increasing costs by 15%-20%, suitable for dusty and high-humidity environments. Additionally, low-noise models (no-load noise ≤45dB) are 10,000-15,000 RMB more expensive than standard models, suitable for noise-sensitive locations such as hospitals and office buildings.

Brand and Service: Avoiding Hidden After-Sales Risks

A significant portion of the price difference between reputable manufacturers and smaller factories lies in warranty and service. Our factory's SCB11 all-copper models are 20,000-30,000 RMB more expensive than those from smaller manufacturers, but we offer a 5-year warranty on core components (windings, iron core), including on-site installation and commissioning, and annual inspection services, avoiding extra costs due to improper installation or fault repairs. While smaller factories offer lower prices, they typically only provide a 1-year warranty and lack a professional maintenance team, resulting in significantly higher costs for future fault handling.

Market Fluctuations: The Manufacturer Teaches You How to Lock in a Reasonable Price

Copper accounts for 30%-40% of the total cost of a transformer. Short-term increases in copper prices will lead to a 5%-10% increase in the price of a single unit. During peak seasons (March-June, September-November), due to concentrated project procurement, prices are 3%-5% higher than in the off-season. We recommend that if the project cycle allows, customers should purchase during the off-season when copper prices are stable, or sign a long-term agreement with the manufacturer to lock in prices; if immediate delivery is needed, our factory keeps SCB11 and SCB13 series in stock, with a delivery time of 7-15 days. The price is slightly higher than customized models but without rush fees.

Manufacturer's Targeted Selection Advice: The Right Fit for the Application is the Optimal Solution

Avoid Low-Price Traps: Verify Materials and Qualifications

When purchasing, be sure to require the manufacturer to provide material testing reports and production qualification certificates to confirm that the windings are all copper and the iron core is made of high-permeability silicon steel sheets. Avoid purchasing products that use "copper-aluminum mixed materials disguised as all-copper," as these devices are prone to overheating and frequent failures, increasing downtime losses. Our factory supports on-site material inspection by customers, ensuring transparency and traceability throughout the process.

Select Based on Application Scenario: Balancing Initial and Long-Term Costs

Basic models can be used for temporary power distribution and low-load scenarios, but for fixed commercial and industrial applications and densely populated areas (commercial complexes, data centers), prioritize all-copper, IP30 protection, and Level 1 energy efficiency models. For example, after a foreign-funded enterprise in Suzhou Industrial Park adopted our SCB11 all-copper model, the annual downtime due to failures decreased from 37 hours to 2 hours, saving nearly 10,000 RMB in energy costs annually.

Reserve Upgrade Space: Adapting to Future Needs

If there are future needs for load expansion or intelligent upgrades, reserve interfaces during the selection process. Our factory offers models with pre-reserved IoT monitoring interfaces, allowing for easy upgrades to intelligent operation and maintenance functions without disassembling the equipment later, saving 30% on costs compared to retrofitting.

Industry Trends: Must-See Procurement Directions for 2026

With the energy transition and tightening energy efficiency policies, high-efficiency, intelligent dry-type transformers are becoming mainstream. The market share of SCB13 and SCB14 series is continuously growing, while inefficient models are gradually being phased out. In the future, products with intelligent monitoring and low-carbon manufacturing processes will command a higher premium, but as industry consolidation increases, the price of mainstream all-copper models is expected to stabilize. As a manufacturer, we are continuously optimizing our production processes to provide more cost-effective solutions for our customers while ensuring quality.
