China has emerged as a global powerhouse in electrical equipment manufacturing, combining advanced technology, rigorous quality standards, and cost-effective production. At the forefront of this industry stands Jiangsu Yawei Transformer Co., Ltd.—a leading power transformer factory dedicated to serving global power grid infrastructure projects. As a professional manufacturer of power transformers and high-voltage electrical equipment, we specialize in producing transformers for substations, distribution systems, and transmission lines. Our products comply with IEC, IEEE, and other international standards, ensuring seamless integration into any grid worldwide. With deep engineering expertise and an unwavering commitment to continuous technological and quality improvements, Yawei is the trusted partner for infrastructure developers across continents.
Why Global Projects Choose Yawei as Their Chinese Transformer Partner
International infrastructure projects demand suppliers who understand global standards, logistics, and project management. Jiangsu Yawei has built its reputation on meeting these demands consistently. Global engineering contractors, utility companies, and EPC firms choose Yawei because we offer:
International compliance: Full adherence to IEC, IEEE, and other standards eliminates requalification risks.
Proven export experience: Decades of shipping transformers to Asia, Africa, South America, the Middle East, and Europe.
Engineering collaboration: Our technical team works directly with your engineers to ensure precise specifications.
Competitive lead times: Large-scale manufacturing capacity enables on-time delivery even for urgent projects.
Value without compromise: High-quality materials and processes at factory-direct prices.
Comprehensive Product Portfolio for Grid Infrastructure
Yawei’s product range covers every major application within power grid infrastructure:
Substation Transformers
Substations are the control centers of any grid. Yawei manufactures power transformers from 5 MVA to 120 MVA with voltage classes up to 220 kV. Features include on-load tap changers, low partial discharge levels, and high short-circuit withstand capability. Cooling configurations (ONAN, ONAF, OFAF) are selected based on local ambient conditions and load profiles.
Distribution Transformers
For the final link to end-users, Yawei offers oil-immersed and dry-type distribution transformers from 50 kVA to 5 MVA. Pole-mounted, pad-mounted, and ground-mounted configurations are available. Amorphous metal core options provide ultra-low no-load losses for projects prioritizing energy efficiency.
Transmission Transformers
Long-distance high-voltage transmission requires transformers of exceptional robustness. Yawei designs auto-transformers and generator step-up (GSU) transformers for voltage levels up to 220 kV and beyond. These units feature enhanced insulation systems, superior short-circuit strength, and corrosion-resistant finishes for harsh environments.
High-Voltage Electrical Equipment
Complementing our transformers, Yawei manufactures HV switchgear, ring main units, load break switches, and surge arresters—providing complete substation solutions from a single supplier.
Compliance with International Standards: IEC, IEEE, and More
Global grid infrastructure projects cannot tolerate non-compliant equipment. Jiangsu Yawei ensures that every transformer leaving our factory meets or exceeds the requirements of:
IEC 60076 series – Power transformers (international markets)
IEEE C57.12 series – Distribution and power transformers (North American specifications)
IEC 62271 series – High-voltage switchgear
GB/T standards – Chinese national standards (for projects within China or accepting equivalent certifications)
Our in-house high-voltage testing laboratory performs routine tests on every unit, type tests on representative samples, and special tests as requested by clients. Third-party witnessed tests (SGS, TÜV, or customer representatives) are standard practice for international projects.
Engineering Solutions for Diverse Global Conditions
China’s manufacturing expertise is valuable, but local engineering adaptation is essential. Yawei leverages decades of experience to tailor transformers for specific project environments:
High altitude (above 2000m): Corrected dielectric withstand and cooling system adjustments.
Extreme temperatures (-40°C to +55°C): Special oil grades, low-temperature starting provisions, and optimized radiator sizing.
Coastal and industrial zones: C5-M corrosion protection, stainless steel hardware, and sealed designs to prevent moisture ingress.
Seismic zones: Base isolation systems and reinforced tank construction tested to IEEE 693 or equivalent standards.
Limited transport access: Split-phase designs, compact configurations, or mobile transformer solutions.
Continuous Technological and Quality Improvements
Being a leading factory means never standing still. Jiangsu Yawei invests continuously in R&D and manufacturing process improvements:
Technological Advancements
Amorphous metal cores reducing no-load losses by 60-70% compared to conventional silicon steel.
Natural ester fluids providing fire-safe, biodegradable alternatives to mineral oil.
Smart transformer monitoring with embedded fiber-optic sensors and DGA ports for predictive maintenance.
3D magnetic field simulation optimizing core and winding designs to minimize stray losses.
Quality Improvements
ISO 9001, ISO 14001, and ISO 45001 certified management systems.
Lean manufacturing and Six Sigma reducing defects and improving consistency.
Supplier quality audits ensuring only premium materials enter our factory.
Continuous employee training maintaining high skill levels across all production stages.
