medium voltage transformer price list
The following is the price reference and key information compilation of **Medium Voltage Transformers**, covering
different types, capacities, and application scenarios:
I. Classification and Price Range of Medium Voltage Transformers
Medium voltage usually refers to the voltage level of **1kV~35kV**. Common types include **oil-immersed transformers*
*, **dry-type transformers**, **current transformers (CT)**, **voltage transformers (VT)**, etc. The following is the price
reference in the international market in 2024:
1. Oil-Immersed Distribution Transformers (10kV~35kV)
| Capacity (kVA) | Voltage Level | Price Range (USD per unit) | Typical Applications |
| 100 | 10kV | $1,000~$3,000 | Small-scale commerce, community power distribution |
| 250 | 10kV | $2,000~$5,000 | Industrial branch lines, small factories |
| 630 | 10kV | $5,000~$12,000 | Medium-sized industries, commercial complexes |
| 1250 | 10kV | $10,000~$25,000 | Large factories, regional substations |
| 2000 | 35kV | $20,000~$50,000 | High-voltage power transmission and distribution, park power supply |
2. Dry-Type Transformers (10kV~35kV)
| Capacity (kVA) | Cooling Method | Price Range (USD per unit) | Advantages |
| 200 | Air cooling | $2,500~$6,000 | Low noise, maintenance-free |
| 500 | Forced air cooling | $5,000~$15,000 | Indoor power distribution, data centers |
| 1000 | Liquid cooling | $12,000~$30,000 | High power density, industrial applications |
3. Current Transformers (CT) and Voltage Transformers (VT)
| Type | Voltage Level | Price Range (USD per unit) | Usage |
| Medium voltage CT | 10kV~35kV | $200~$2,000 | Current measurement and protection |
| Medium voltage VT | 10kV~35kV | $300~$5,000 | Voltage monitoring and relay protection |
II. Core Factors Affecting the Price
1. **Capacity and Voltage Level**:
- The larger the capacity and the higher the voltage level, the price increases exponentially (e.g., 10kV
100kVA vs. 35kV 2000kVA).
2. **Cooling Method**:
- Oil-immersed (low cost) < Dry-type (maintenance-free) < Liquid cooling (high power).
3. **Materials and Processes**:
- Copper winding vs. Aluminum winding (Copper core is 20%~30% more expensive), fully sealed design vs.
ordinary casing.
4. **Certification and Standards**:
- Products that comply with standards such as IEC, ANSI, and GB require additional certification costs.
5. **Customization Requirements**:
- Special voltage ratios, explosion-proof designs, intelligent monitoring functions (such as SCADA interfaces)
will increase costs.
III. References of International Market Suppliers
1. **Wankong Electric in China**:
- 10kV 100kVA oil-immersed transformer: **$800~$2,000** (MOQ 1 unit).
- 35kV 2000kVA dry-type transformer: **$15,000~$40,000** (Customization required).
2. **Indian Suppliers** (IndiaMART):
- 11kV CT: **₹5,000~₹10,000** (Approximately $60~$120).
- 3-phase 630kVA transformer: **₹5.7 lakh** (Approximately $7,000).
3. **European and American Brands** (such as ABB, Siemens):
- The price of products with the same specifications is **2~4 times** that of Chinese/Indian products, but they
offer a longer warranty period (5~10 years).
IV. Procurement Suggestions
1. **Clarify Parameters**:
- Provide parameters such as voltage level, capacity, connection group (such as Dyn11), and short-circuit impedance
to obtain accurate quotations.
2. **Compare Suppliers**:
- Chinese suppliers offer high cost-effectiveness, while European and American brands are suitable for projects with
extremely high reliability requirements.
3. **Consider Additional Costs**:
- Transportation costs (accounting for 5%~15% of the total price), installation and commissioning fees (approximately
$500~$2,000 per unit), and import duties (depending on the region).
