introduction of 3150 kVA substation Transformer
GNEE TRANSFORMER supplies 3150 kVA oil immersed substation transformer.
This oil-filled transformer offers exceptional performance, with features such as low loss, low noise, and high efficiency.Its tank is constructed from 304 stainless steel, which effectively prevents corrosion and withstands harsh environments. Featuring double-wound copper material, it includes five-step voltage regulation of ±2.5%. The transformer's winding temperature rise is 55°C, allowing it to operate continuously in high-temperature conditions.
