Certifications IEC 62271-200, IEC 694, GB3906, DIN VDE 0670
The 63kVA 33kV/0.433kV Dry Type Transformer is compatible with overseas 33kV voltage systems. Leveraging its own factory's mature customized production capabilities, it can meet the voltage parameters and regulatory requirements of different regions, providing safe and stable power distribution for small factories, commercial areas, and remote sites overseas, showcasing Huajidian's professional manufacturing standards.
We can provide a full range of technical services for overseas projects, covering selection and design, installation guidance, and after-sales maintenance. Our professional foreign trade team can also assist clients with product certification and technical integration, reducing project implementation risks. Based in China, we strictly adhere to international power standards to create high-performance, cost-effective power equipment for global clients.
The core uses high-permeability, oriented cold-rolled silicon steel sheets, combined with a stepped core structure and fully oblique joint technology. Both no-load and load losses are superior to industry standards, effectively reducing electricity expenses in the long term, meeting the cost control needs of small industrial and commercial projects.
The core is reinforced with high strength, resulting in low operating noise and vibration, minimizing environmental interference. It is suitable for small factories, community power distribution, and other scenarios.
The windings contain no flammable insulating oil, eliminating the risk of fire, explosion, and oil leakage inherent in oil-immersed transformers. It complies with fire safety regulations and can be installed in various scenarios such as buildings, basements, and small outdoor power distribution rooms.
The cast windings are integrally molded, possessing high mechanical strength and resisting external impacts during transportation, installation, and operation. They exhibit excellent short-circuit resistance and can operate stably even during sudden power grid short circuits.
The smooth resin surface is resistant to dust accumulation, requiring only simple wiping daily. No oil changes or filters are needed, resulting in extremely low maintenance costs, making it suitable for long-term unattended use in remote areas.
The 63kVA 33kV/0.433kV Dry Type Transformer comes standard with an air-cooled (AN) mode, relying on natural convection for heat dissipation. No additional fan is required, resulting in a simple structure, fewer potential failure points, and no additional energy consumption.
The entire unit is equipped with a high-strength steel frame and pre-drilled standard mounting holes, supporting multiple installation methods. Transportation and installation are convenient, meeting the rapid deployment needs of small projects.
Huajidian boasts a professional dry-type transformer R&D team. For the special 33kV voltage level, it can provide customized solutions based on the voltage, frequency, and industry standards of various countries, and has already delivered compatible products for multiple overseas projects.
From silicon steel sheets and copper materials to resin casting, every process undergoes rigorous inspection. Before leaving the factory, multiple tests are conducted, including insulation withstand voltage, partial discharge, and temperature rise. Products comply with IEC international standards and local power regulations, ensuring stable and reliable quality.
The factory is equipped with advanced vacuum casting equipment, core processing lines, and a professional testing laboratory, achieving integrated production from raw materials to finished products. This ensures on-time delivery of large-volume orders and rapid response to small-batch customized needs.
A remote rural power supply project in Southeast Asia selected 12 Huajidian 63kVA 33kV/0.433kV Dry Type Transformers to build the regional distribution network. The area has scattered residents, limited on-site maintenance conditions, and stringent local fire safety requirements.
The equipment has been operating stably for over two years since its commissioning. Its self-cooling structure is well-suited to the local environment, and its low-loss design saves the project approximately 15% on electricity annually. The oil-free structure completely eliminates fire risks, and its low-noise operation has not affected residents' lives. The client highly appreciates the product quality and comprehensive service, and both parties have reached a long-term cooperation agreement for future expansion projects.
Q1: Can this 63kVA dry-type transformer be installed in a confined indoor space?
A1: Yes. The product uses a full resin casting structure, contains no insulating oil, poses no fire or oil leakage risks, meets fire safety requirements, and can be installed normally in confined areas such as basements and indoor power distribution rooms.
Q2: What kind of heat dissipation method does the 63kVA 33kV/0.433kV Dry Type Transformer use, and does it require additional cooling equipment?
A2: The equipment uses an air self-cooling mode, relying on natural air convection for heat dissipation. No auxiliary cooling devices such as fans are required, resulting in a simple structure and low failure rate.
Q3: Can the product be adapted to the voltage and industry standards of different countries?
A3: Yes. We have mature customized R&D and production capabilities, and can adjust product solutions according to local voltage, frequency, and regulations to meet the usage requirements of different overseas markets.
