Global Certification Standards
Our H61 Distribution Transformer strictly complies with international mainstream power equipment standards and European grid access specifications. The product fully conforms to IEC 60076 international transformer standards, EN 60076 European standard and national GB/T 1094 series standards. It has obtained CE certification (LVD/EMC) for EU market entry and ISO9001 quality management system certification. Each transformer undergoes rigorous factory testing including partial discharge detection, power frequency withstand voltage test, short-circuit resistance test, temperature rise test and full-load continuous operation test, fully meeting global grid safety and energy efficiency access standards.

Exported Countries & Market Coverage
Benefiting from standard H61 design, ultra-low loss performance and full international certifications, our H61 Distribution Transformers have been widely exported to global high-standard grid markets. It has stable long-term operation cases in European countries (Italy, Spain, Poland, Romania, Bulgaria), Southeast Asia (Thailand, Malaysia, Indonesia, Vietnam), Middle East (UAE, Saudi Arabia, Qatar), Africa (South Africa, Ghana, Kenya, Nigeria), Central Asia (Kazakhstan, Uzbekistan) and South America (Chile, Peru, Colombia). The product adapts to 50Hz/60Hz dual-frequency grid systems and meets high-standard energy-saving and safety requirements of European and international power grids.

Core Product Features
1. H61 Standard Ultra-Low Loss Design: Adopts high-performance grain-oriented silicon steel sheet and optimized magnetic circuit structure, strictly following H61 industry design specifications. The no-load loss and load loss are far lower than conventional transformers, reaching the latest international super energy-saving level, effectively reducing long-term grid energy waste.
2. Stable Oil-Immersed Cooling System: Adopts ONAN natural oil circulation cooling mode, with reasonable internal oil circuit layout and large-area heat dissipation structure. It ensures uniform heat dissipation inside the equipment, effectively controls temperature rise under full-load and intermittent overload operation, and avoids thermal aging of insulating materials.
3. Excellent Anti-Short Circuit & Anti-Impact Performance: The winding adopts reinforced fastening structure and high-strength insulating materials. Through professional short-circuit resistance structural design, it can resist instantaneous current impact and external grid fluctuation, effectively preventing winding deformation and equipment damage, and improving operational stability in complex grid environments.
4. Low Noise & Environmentally Friendly Operation: Optimized core lamination process and vibration reduction structure design effectively suppress electromagnetic noise and mechanical vibration. The full-sealed oil tank structure avoids insulating oil leakage, realizing low noise, pollution-free and environmentally friendly operation, suitable for urban and residential dense areas.
5. Strong Environmental Adaptability: The outer shell adopts high-strength steel plate and anti-corrosion electrostatic spraying treatment, with good waterproof, dustproof, rust-proof and anti-aging performance. It can stably adapt to various climatic environments such as high temperature, low temperature, humidity and sandstorm, suitable for indoor and outdoor long-term unattended operation.

Product Advantages
1. Superior Energy-Saving & Low Operating Cost: H61 high-standard energy-saving design greatly reduces no-load and load power consumption. Although the initial investment is moderate, it can save a large amount of electricity costs for users in long-term operation, with significant economic and energy-saving benefits.
2. High Safety & Low Failure Rate: Adopts mature and reliable H61 standard system and high-quality matching accessories. With strict factory testing and stable structural performance, the equipment has strong grid adaptability and extremely low failure rate, reducing maintenance and replacement costs caused by equipment failure.
3. Green & Low-Carbon & Policy Compliant: Meet international and European energy-saving and carbon emission reduction standards, fully compliant with global green power grid construction policies. It is the preferred model for grid upgrading, new energy matching and energy-saving renovation projects in various countries.
4. Easy Installation & Wide Compatibility: Adopts universal standard size and interface design, compatible with most global grid distribution systems. It supports indoor platform installation and outdoor floor-mounted installation, with simple on-site construction, short commissioning cycle and strong project adaptability.
5. Standardized Customization & Complete Service: Support customized voltage ratio, capacity, wiring group and protection configuration according to user project requirements. Equipped with complete international certification documents and multilingual technical materials, providing global professional after-sales technical support and long-term operation guidance.
