Specially designed for supporting high‑voltage frequency converters, this transformer adopts Class‑H insulating materials. It realizes multi‑pulse rectification by multi‑winding phase‑shifting technology, which can effectively suppress harmonics and supply stable isolated power for frequency‑conversion systems. Its capacity ranges from 300 kVA to 10000 kVA, applicable for voltage classes of 3 kV, 6 kV, 10 kV, etc.
Excellent heat resistance, moisture‑proof and flame‑retardant performance. Compact structural design for small footprint; high phase‑shift accuracy and good grid‑side power factor; strong capability of short‑circuit‑withstanding and thermal‑cold shock resistance. Easy for routine maintenance and suitable for complex working conditions.
Widely used in metallurgy, petrochemical, electric power, mining, building materials and other industries. It is suitable for energy‑saving retrofitting with variable‑frequency speed regulation of fans, pumps and other equipment, as well as scenarios with high fire‑protection requirements and large load fluctuations such as offshore oil platforms and water‑works.
