1. China’s Green Manufacturing Breakthroughs: A Group Success
China has established a comprehensive competitive advantage in the dry-type transformer green manufacturing sector through collective innovation rather than individual efforts. Key achievements span the entire value chain:
Green Design Innovations
- Three-dimensional wound core technology: Chinese companies have developed proprietary 3D wound core transformers with significantly reduced core loss (up to 25% lower than traditional designs)
- High-efficiency design: SCB18/SCB20 series products have been mass-produced by over 75% of mainstream manufacturers, achieving “ultra-first-tier” energy efficiency levels (15% lower no-load loss, 10% lower load loss than standard first-tier efficiency)
Material Revolution
- Vegetable oil insulation: China leads in developing vegetable oil dry-type transformers using natural esters extracted from plant seeds (soybean, rapeseed). These offer 97% biodegradability, zero pollution risk, and enhanced fire safety
- Amorphous alloy breakthrough: Domestic amorphous raw material development has created a solid foundation for amorphous dry-type transformers, achieving 70% lower no-load losses compared to conventional models
- Water-based eco-coatings: Chinese enterprises provide locally sourced, reliable water-based coatings that eliminate VOC emissions during production
Manufacturing & Performance Advantages
- Superior efficiency: Products now meet GB20052-2020 standard with first-tier energy efficiency penetration reaching 63.5% (up from 41.2% in 2020)
- Ultra-low environmental impact: Green transformers feature >98% material recyclability, <2% combustible content, and 90% lower production energy consumption compared to conventional manufacturing
- Smart manufacturing integration: About 34% of high-end market products now feature integrated online temperature control, partial discharge monitoring, and remote communication
2. Market Leadership & Global Impact
China has become the world’s largest dry-type transformer producer and exporter:
| Metric | Value | Global Position |
|---|---|---|
| Global market share | 38% (2025), projected 42% by 2030 | #1 |
| Export volume | 46% of global shipments | Largest exporter |
| Production capacity | 15.8 million units (2025), 23.4 million by 2030 | #1 |
| Growth rate | 13.1% CAGR | Faster than global average |
This dominance stems from China’s complete industrial chain, cost competitiveness, and technological innovation under the “dual carbon” strategy.
3. Key Green Manufacturing Breakthroughs
1) Vegetable Oil Dry-Type Transformers
- Core advantages: Non-toxic, fully biodegradable, high flash point (300+°C), and no environmental pollution risk when leaked
- China’s edge: Complete independent intellectual property rights from raw material production to final product, with 500kV vegetable oil transformers already in commercial operation
2) Three-dimensional Wound Core Technology
- Innovative structure: Eliminates traditional butt joints, reducing magnetic leakage and core loss by 15-20%
- Manufacturing benefits: Simplified production process, reduced material usage, and enhanced mechanical stability
3) Amorphous Alloy Applications
- Energy efficiency leap: SCBH15 series amorphous dry-type transformers achieve 70% lower no-load losses than conventional S10 series
- Material innovation: Domestic amorphous strip production now meets international quality standards at competitive costs
4) Biodegradable Insulation Materials
- Game-changing breakthrough: China has developed world’s first 35kV degradable epoxy resin cast dry-type transformer that fully degrades within 24 hours, enabling closed-loop resource utilization
4. Current Challenges & Future Outlook
Challenges
- Awareness gap: Many traditional manufacturers still lack understanding of green manufacturing concepts and implementation capabilities
- International competition: While global players are withdrawing from certain segments, competition remains fierce in high-end markets
- Market acceptance: Some customers still prioritize initial cost over long-term environmental benefits
Strategic Opportunities
- Policy tailwind: China’s “Made in China 2025” and “dual carbon” goals provide strong policy support for green manufacturing, including tax incentives and government procurement preferences
- Market expansion: Global demand for eco-friendly transformers is growing, especially in urban infrastructure, renewable energy, and data centers
- Technology leadership: By continuing to invest in R&D, Chinese companies can solidify their position as global green transformer innovators
5. CHH Power’s Green Manufacturing Strategy
As a forward-looking enterprise, CHH Power is committed to leading the green transformation with three core initiatives:
- Complete green product portfolio: Develop and promote vegetable oil transformers, 3D wound core dry types, and amorphous alloy products that exceed international energy efficiency standards
- Full lifecycle sustainability:
