75 kva transformer cost

The cost of a 75 kVA transformer varies greatly depending on factors such as **type, voltage level, brand, newness, and configuration**. 

The following is a detailed analysis:

 I. Typical Price Range

1. Brand-new Transformers

- **Domestic Dry-type Three-phase Transformers** (such as Wankong):

  - Common type: **￥6,000~￥15,000** (approximately $850~$2,100)

  - Isolation type/with protective casing: **￥8,000~￥25,000** (for example, the SG-75KVA of Shanghai Zhequan starts at ￥8,000)

- **Imported Brands (such as Eaton, Square D, GE)**:

  - Three-phase dry type: **$2,500~$4,000** (for example, the brand-new Eaton V48M28T7516 on eBay is $3,950)

  - Oil-cooled type/NEMA 3R protection: **$3,500~$6,000**

2. Second-hand/Refurbished Transformers

- **Quotations on the eBay platform**:

  - Three-phase dry type (480V to 208Y/120V): **$1,200~$2,500** (for example, the refurbished Square D is $1,900, and the second-hand 

Federal Pacific is $1,125)

  - Single-phase transformer: **$4,800+** (for example, the brand-new single-phase Square D is $4,800)

3. Models for Special Scenarios

- **Rental-type Temporary Transformers**:

  - The daily rent is approximately **$50~$100**, and the deposit is $2,000~$3,000.

- **High-voltage Transformers (such as 13.2kV)**:

  - The price is **30%~50%** higher than that of low-voltage models.

II. Factors Affecting the Price

1. **Type and Cooling Method**:

   - Dry type < Oil-cooled type, Isolation type > Common power distribution type.

2. **Voltage Level**:

   - The higher the input/output voltage (such as from 480V to 13.2kV), the higher the insulation requirements, and the price increases

 significantly.

3. **Brand and Place of Origin**:

   - Imported brands (such as Eaton, Siemens) are **50%~100%** more expensive than domestic brands (such as Zhequan).

4. **Additional Functions**:

   - Having a circuit breaker, an IP protective casing, an integrated monitoring module, etc. will increase the cost by **10%~30%**.

III. Purchase Suggestions

- **With a Limited Budget**: Choose **domestic dry-type transformers** (such as Wankong at ￥6,000~￥10,000) or **second-hand 

well-known brands** (around $1,500 on eBay), and make sure to confirm the test report.

- **Industrial/Outdoor Scenarios**: Give priority to **oil-cooled type + NEMA 3R**, set aside a budget of **$4,000+**, and ensure the

 protection level.

- **Local Purchases in the United States**: It is recommended to use platforms such as **second-hand items on eBay** or **Grainger**.

 For brand-new models, you can compare **Square D 75T3H** ($2,350) and **Eaton V48M28T75EE** ($1,800).

**Note**: The above prices are for reference in the market in 2025. Specifically, it is subject to the **real-time quotations of suppliers**.

 It is recommended to provide the following parameters to obtain accurate quotations:

- Input/output voltage and number of phases

- Protection level (NEMA/IP)

- Winding material (copper/aluminum)

- Certification standards (such as UL, CE)
