Description
The manufacturer produces oil-immersed transformers, from distribution to power transformers for power systems. According to the company's overview brochure, the power transformer programme covers three-phase units with voltages up to 550 kV and power up to 800 MVA; transformer production is located in Korea (Cheongju, Cheonan and Busan plants) and abroad. Oil-immersed transformers of the medium voltage class (manufacturer's catalogue 2019): voltage up to 69 kV, power up to 80 MVA. Standard series: three-phase 22.9 / 3.3 or 6.6 kV units of 3000–50,000 kVA; 22.9 kV / LV — 100–750 kVA; 6.6–3.3 kV / LV — 100–3000 kVA. Insulation class A (105 °C), winding temperature rise 65 K and oil temperature rise 60 K; cooling systems with natural and forced oil circulation (ON / OF / OD) and air or water external cooling (AN / AF / WF); windings of aluminium or copper; efficiency at full load about 98.7–99.4 %. A wide choice of bushings, on-load tap changers for 100, 150 and 300 A, fuse protection options and special tests. Standards: IEC 60076 and ANSI/IEEE C57. Quality is confirmed by an ISO 9001 system and by tests in the company's own institute PT&T (Power Testing & Technology), and also with partners UL, CE, KEMA and CESI. The manufacturer supplies equipment to 224 customers in 77 countries through 7 foreign companies and 12 branches (according to the catalogue). Applications: power system substations of 110–500 kV, unit transformers of power plants, main step-down substations of industrial enterprises (metallurgy, oil and gas, chemicals), renewable energy substations, and distribution networks of 6–35 kV. Note: detailed technical parameters of the extra-high-voltage power transformers (vector groups, losses, impedance voltage) are not given in the available materials and are determined by the technical specification.
