South Korea stands as a global titan in semiconductor manufacturing, automotive innovation, and battery technology. For industries operating in high-precision environments like the "Gyeonggi-do Semiconductor Cluster" or the shipyards of Ulsan, Isolation Transformers are not just components—they are the critical guardians of power quality. As a leading manufacturer serving the Korean peninsula, we understand that the demand for galvanic isolation and harmonic suppression has never been higher.
Korea’s transition towards "Industry 4.0" and smart manufacturing requires electrical infrastructure that can mitigate transient spikes and ensure zero-interference between sensitive CNC machinery and the power grid. Our isolation transformers are engineered to meet KEPCO (Korea Electric Power Corporation) standards while integrating international E-E-A-T principles for reliability and safety.
Our transformers utilize Cold-Rolled Grain-Oriented (CRGO) silicon steel and advanced amorphous alloy cores to minimize no-load losses. For Korean customers focusing on RE100 and ESG compliance, our SCB series dry-type transformers offer the highest energy efficiency ratios in the industry.
Given Korea's coastal industrial zones, our transformers feature helical coil epoxy resin casting. This ensures moisture resistance, flame retardancy, and high mechanical strength against the vibrations common in heavy shipbuilding and port crane operations.
With multi-tap configurations (380V/220V/440V/480V), we provide seamless integration for imported European or American machinery into the Korean 60Hz grid environment. Our SG Series provides industrial-grade step-up/down capabilities with less than 1% voltage fluctuation.
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 (S11, S13, S14, and S20 series), dry-type transformers (SCB10, SCB11, SCB13, and SCBH15 series), as well as rectifier and furnace transformers. These integrated solutions are widely applied in power grid construction, industrial manufacturing, mining, and renewable energy projects worldwide.
Procuring isolation transformers for the Korean market requires more than just a datasheet. It requires an understanding of local regulatory frameworks like the KC (Korea Certification) and KS (Korean Industrial Standards). Our global supply chain team ensures that every unit shipped to Korea includes:
Isolation transformers provide galvanic isolation, separating the primary and secondary circuits. This is vital for fabs in Korea as it eliminates ground loops, reduces common-mode noise, and protects sensitive photolithography equipment from voltage transients on the KEPCO grid.
Yes. We specifically manufacture units designed for the Korean 60Hz frequency and standard voltages (220V Single-phase, 380V Three-phase). We also provide custom taps for 440V and 480V for specialized industrial equipment.
Standard units are often in stock. For custom engineered solutions, the production cycle is typically 15-25 days, followed by 5-7 days for shipping via major maritime routes to Incheon or Busan ports.
Our products are manufactured according to IEC standards and we provide all necessary documentation (test reports, CE, ISO) required to facilitate local KC certification and safety inspections by KESCO (Korea Electrical Safety Corporation).
As the world moves toward decentralized energy, our technical roadmap includes the integration of IoT-based monitoring systems. Future isolation transformers will not only isolate power but also provide real-time data on winding temperature, load efficiency, and harmonic distortion directly to your facility's Energy Management System (EMS). We are committed to supporting South Korea's "Green New Deal" by producing transformers with ultra-low loss cores and 100% recyclable insulation materials.
