I 04 05 Power Transformers Technology Hyosung is the leading supplier of the power transformer industry. Starting with the development of the 154kV high-voltage transformer in 1969, Hyosung introduced the 345kV and the 765kV transformers subsequently for the first time in the country, and the sixth in the world. Hyosung’s power transformers are designed to withstand all environmental hazards. In the rated power range up to 2000MVA and operating voltage up to 765kV, these transformers have off- load or on-load tap changers to adapt them to various network conditions. Hyosung manufactures transformers under IEC, JEC, ANSI, BS and all required national standards. Hyosung offers individual solutions for satisfying requirements related to types of operation, low noise and low losses, connection technology, type of cooling, transportation, installation and so on. Various Types Various types of transformers are available according to the specific requirements including single phase and three phase transformers, auto and multi-winding transformers, reactors and transformers for special applications such as furnace transformer, rectifier transformer and more. Fit Design If there are any constraints related to transportation or site conditions, we can offer fit design transformer to ensure smooth shipping and installation. We also possess experience in transportation by airplanes. Safety To ensure safe operation of our transformers, potential hazards are identified and eliminated at all stages. Safety during installation is ensured by extending on-site support to customers by our experienced and efficient supervisor. Flexible Manufacturing System Our production flow management system is fully computerized and automatically controlled to prioritize and finalize the manufacturing schedules based on delivery dates. This system yields the most optimized use of resources and also enables us to accommodate the unexpected and/or urgent orders by customers with shorter time delivery requirements. Simple Handling and Maintenance Compact design of our transformers ensure easy and smooth handling of transformers whereas Efficient design and manufacturing process and use of reliable components and accessories from reputed manufacturers ensure the trouble free operation rendering low maintenance cost of the equipment. Customized Solutions Tailor-made customized transformers can also be supplied based on the specific requirements. Smart Grid Enabled Design, manufacture, installation, and maintenance &repair of electric power facilities (transformer, GIS, and switchboard) are based on technology and knowhow accumulated over the past 35 years. By linking Hyosung’s new preventive diagnostic system, users can diagnose the status of the equipment and schedule inspections through data received in real-time, including partial discharge and insulation oil deterioration, OLTC monitoring, insulation oil temperature, operation status of cooling fans, pumps, motor operation, and oil filter pressure.

Design CConcept Hyosung’s transformers are designed and manufactured through verification from the design stage using design program, electromagnetic field analysis program, and structural analysis program. Dielectric Strength Hyosung transformers offer superior dielectric strength to withstand impulse voltage. Our advanced technology design principles ensure low capacitance between winding and the ground for proper coordination of insulating material mitigating any potential creepage issues. Thermal Capability The coils that form the electric circuit inside the transformer as well as the core material which creates the magnetic circuit must dissipate heat effectively. This heat must be released through the insulating oil which in turn radiates to the air through the cooler or radiator system. This cooling effect is vital as it is directly linked to insulation life and the total capacity of the transformer. Hyosung’s transformers emphasize improving cooling performance as well as regulating the temperature of the hottest spots by using an advanced cooling system. Mechanical Strength Hyosung transformers exhibit excellent mechanical strength because the design is able to distribute mechanical force evenly in event of a short circuit condition. Consideration is also given to engineering for overseas and rail transportation requirements required for delivery to the customer’s site.
