As Greece continues its ambitious "Greece 2.0" National Recovery and Resilience Plan, the modernization of the electrical grid has become a cornerstone of national development. Vacuum Pressure Impregnated (VPI) Transformers have emerged as the preferred technology for Greece's unique geographical and industrial challenges. From the humid Mediterranean coastlines of Piraeus to the seismic-active regions of the Aegean islands, VPI technology offers a "dry" solution that balances performance, environmental safety, and structural integrity.
Greece’s energy landscape is shifting rapidly from coal-fired plants in Western Macedonia toward distributed renewable energy sources. This transition requires transformers that can handle fluctuating loads and harsh environments. Unlike traditional oil-immersed units, VPI transformers are moisture-resistant and flame-retardant, making them ideal for high-density tourist areas, historic Athens neighborhoods, and sensitive island ecosystems where oil leakage could cause catastrophic environmental damage.
High-rise buildings and commercial malls in Marousi require self-extinguishing transformers to comply with strict EU fire safety regulations. VPI units provide this without the explosive risks of oil.
The Port of Piraeus, one of the busiest in Europe, utilizes VPI technology for shore-to-ship power (cold ironing), where salt-air corrosion resistance is non-negotiable.
Solar parks in Thessaly and wind farms in Crete benefit from the VPI's ability to withstand thermal cycling and harmonic distortions common in green energy inverters.
The VPI process involves placing the transformer’s core and coil assembly into a vacuum chamber. All air and moisture are removed, and a specialized resin is introduced under high pressure. This ensures that every crevice of the insulation is filled, eliminating "partial discharge" which is the leading cause of transformer failure in high-humidity Greek summers. In contrast to Cast Resin (CRT) transformers, VPI units offer better mechanical flexibility, making them less prone to cracking during the minor seismic events common in the Hellenic arc.
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.
With the strategic partnership between China and Greece (COSCO's investment in Piraeus), the logistical bridge between Henan Pirooz Power and Greek EPC contractors has never been stronger. Greek buyers benefit from:
Procuring transformers for the European market, particularly Greece, requires strict adherence to EN 60076 standards and EcoDesign Directive (EU) No 548/2014. Our VPI units are designed to meet Tier 2 loss requirements, ensuring Greek enterprises reduce their carbon footprint while maximizing energy efficiency.
While global standards exist, Greece has specific secondary distribution needs. We offer 20kV/400V configurations specifically tuned for the Hellenic Public Power Corporation (PPC/DEI) network requirements.
Our VPI transformers use Class H or Class K insulation materials, which are environmentally neutral. At the end of their service life, these units are 90% recyclable, aligning with the EU Circular Economy Action Plan.
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. These products are widely used in power utilities and heavy industries requiring stable and efficient energy distribution.
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.
