Bulgaria, as a key energy hub in the Balkan region, is currently undergoing a significant transformation of its electrical grid. Following the European Green Deal and the Integrated National Energy and Climate Plan (INECP), Bulgaria is prioritizing the modernization of its aging distribution infrastructure. For a Three-phase Distribution Transformer Manufacturer, the Bulgarian market presents unique demands—ranging from the industrial revitalization in Plovdiv to the large-scale renewable energy integration in the Dobrudzha region.
Information Gain: Unlike many standard markets, Bulgaria's distribution network primarily operates on 20kV and 10kV levels, shifting increasingly toward 20kV for medium-voltage efficiency. As an expert factory, we provide specialized step-down solutions that adhere to the IEC 60076 standards and the latest EU Eco-design requirements (Tier 2), ensuring minimal load and no-load losses for Bulgarian utility providers.
Optimized amorphous alloy cores to reduce idle energy waste in Bulgarian rural grids.
Corrosion-resistant coating designed for the high-salinity coastal air of the Black Sea.
High-grade insulation materials that exceed European lifespan benchmarks.
Our R&D department is focused on "Digital Twin" technology integration. Future distribution transformers for the Bulgarian market will include IoT sensors for real-time temperature monitoring, oil gas analysis, and predictive maintenance—crucial for the Electricity System Operator (ESO) of Bulgaria to minimize downtime.
Henan Pirooz Power Co., Ltd. is a comprehensive electrical power equipment manufacturer integrating research and development, engineering design, production, sales, and after-sales service. The company specializes in customized solutions for power transformers and complete sets of transmission and distribution equipment, providing reliable and efficient electrical products for global energy infrastructure projects.
The company operates a modern manufacturing facility with a complete production system covering product design, precision machining, assembly, and full electrical testing. Equipped with advanced production lines and strict quality control procedures, Henan Pirooz Power Co., Ltd. ensures that all products meet international standards and customer-specific technical requirements, maintaining high performance, safety, and durability.
Its core product range includes 10kV–35kV oil-immersed power transformers (such as S11, S13, S14, and S20 series), dry-type transformers (including SCB10, SCB11, SCB13, and SCBH15 series), as well as on-load tap-changing transformers, rectifier transformers, and furnace transformers designed for specialized industrial applications.
In addition to transformers, the company also provides complete electrical system solutions, including high and low voltage switchgear, European-style compact substations, American-style pad-mounted substations, and underground distribution substations. These integrated solutions are widely applied in power grid construction, industrial manufacturing, mining, metallurgy, petrochemicals, transportation systems, and renewable energy projects.
Procuring three-phase transformers for the Bulgarian market requires a deep understanding of European compliance. Our Bulgaria-Focused Export Division ensures that every unit shipped to Sofia, Plovdiv, or Varna meets the following criteria:
Fully compliant with EN 50588-1, ensuring our transformers can be legally installed and operated within the EU grid.
Seamless delivery options to Port of Varna or Port of Burgas, with all documentation prepared for smooth EU customs clearance.
We provide 24/7 technical consulting and have a growing network of local partners for installation and maintenance across Bulgaria.
Yes, we specialize in 20kV/0.4kV and 10kV/0.4kV configurations, which are the standard for Bulgarian medium-voltage distribution. We can also customize tap-changers for specific local requirements.
Standard models (S11/SCB13) usually have a production cycle of 15-25 days. Shipping to the Port of Varna typically takes 30-40 days via sea freight, or faster via intermodal rail options.
Absolutely. All our exports to the EU market comply with the latest Eco-design Directive Tier 2 requirements for reduced load and no-load losses.
Yes, we have supplied numerous 1000kVA to 2500kVA box-type transformers specifically designed for photovoltaic systems in high-temperature environments.
