2025-06-17

If you need dry-type transformers, please contact our company. China is a global leader in the manufacturing and export of dry-type transformers, providing a wide variety of transformer products at competitive prices.


The main advantages of purchasing from China

1. Cost-effectiveness: Significant economies of scale and lower production costs.

2. Manufacturing scale: Numerous factories, ranging from large original equipment manufacturers to specialized workshops.

3. Complete supply chain: Easy access to raw materials (copper, aluminum, steel, epoxy resin, insulating materials).

4. Technical capabilities: Many manufacturers meet international standards (IEC, IEEE, UL, CSA, GB), and provide customized designs.

5. Complete product range: Casting resin (most common), vacuum pressure impregnation (VPI), open-type windings; covering various voltage levels (low voltage, medium voltage), kVA ratings, and protection levels (IP00 to IP55).

Key manufacturing clusters

Jiangsu Province (Changzhou, Yangzhou, Taizhou): Top manufacturers are highly concentrated.

Zhejiang Province (Wenzhou, Hangzhou): Strong strength in electrical components and transformers industry.

Guangdong Province (Foshan - Shunde District, Dongguan, Shenzhen): Important industrial center, especially Foshan/Shunde.

Shanghai: Has some large-scale international and domestic enterprises.

Shandong, Hebei, Fujian: Also have important manufacturing bases.

Types of Chinese suppliers

1. Large original equipment manufacturers (OEM):

Producing under their own brand, usually with strong R&D and quality control capabilities.

Examples: Jiangsu Huapeng Transformer Co., Ltd., TTE Electric, Jiangsu Yinhe Transformer, SGB-SMIT Group (has significant business in China), Hitachi Energy (has factories in China), Siemens (has factories in China), WEG (has factories in China), Jiangsu Jingke Intelligent Electrical Co., Ltd., Zhejiang Yada Electric Co., Ltd.

2. Professional dry-type transformer factories: Many medium-sized companies focus on dry-type transformers and provide high-quality customized products.

3. Export trading companies: Acting as intermediaries; it is essential to verify that their sources of supply come from reputable factories and have technical knowledge. Although it simplifies logistics, it adds an additional layer.

4. "Factory direct sales stores"/small workshops: May have lower prices, but require strict review of their quality and reliability.

Key considerations when purchasing

1. Definition requirements: Voltage (low voltage: <1 kilovolt, medium voltage: typically 3.3 kilovolt - 36 kilovolt), kVA rating, frequency (50 Hz/60 Hz), enclosure type (protection level), cooling category (AN/AF), standards (IEC 60076-11, IEEE C57.12.01, GB 1094.11, UL 506/UL 5085), certifications (ISO 9001, ISO 14001, specific UL/CSA certifications).

2. Supplier review is crucial:

Factory audit: Strongly recommended (in person or through a third party) to assess factory facilities, quality control processes, and technical capabilities.

Technical review: Evaluate design drawings, test reports (routine, type, special) as well as material specifications.

Certification verification: Ensure the certifications are valid and relevant.

Reputation verification: Check reviews, project references, and industry standing. Evaluations on B2B platforms like Alibaba and Made-in-China are a starting point, but more in-depth verification is required.

Financial stability: Ensure they can deliver products and provide warranty support.

3. Quality and price: Do not choose the cheapest option blindly. Achieve a balance between cost and verified quality, reliability, and after-sales service. Request detailed quotations, listing material and specification details.

4. Communication and Documents: Ensure clear communication channels and provide detailed technical/commercial documents (contracts, specifications, test plans, transportation terms - such as FOB, CIF - international trade terms).

5. Logistics and Delivery Dates: Consider transportation costs and possible delays. Discuss the delivery dates in a practical manner.

6. After-sales Service: Clearly define warranty terms, the availability of technical support, and the supply of spare parts.

Finding Suppliers:

B2B Trading Market: Alibaba, Made-in-China Network, Global Sources. Use strict filtering conditions and verify relevant statements.

Industry Directories: Specialized directories for the electrical industry (online and offline).

Trade Exhibitions: Major events such as the China International Industrial Fair (CIIF) held in Shanghai, the Canton Fair (relevant sections), and specialized electrical/transformer exhibitions held in the aforementioned clusters.

Consultants and Purchasing Agents: They may be valuable for market research and expansion, especially for those unfamiliar with the market. 

In conclusion:

China has great potential in the procurement of dry-type transformers. The key to success lies in clearly defining one's own requirements and conducting thorough due diligence on potential suppliers to ensure quality, reliability, and cost-effectiveness. Always prioritize technical capabilities and proven quality control over the lowest price.
