Product Introduction
The S11 and S13 series of fully sealed oil-immersed transformers are expertly engineered for 50Hz AC systems with original working voltages of up to 20kV. These transformers are ideal for power systems in various industries, including petroleum, metallurgy, chemicals, and textiles, as well as large, dust-prone environments.
Introducing the coil core fully sealed distribution transformer, a cutting-edge, low-noise, and low-loss transformer. Its innovative core design significantly reduces no-load loss and no-load current by 60% to 80%, enhancing efficiency. The continuous winding of high and low voltage coils around the core pillar ensures tight winding and excellent concentricity, thereby improving anti-theft features. Experience a noise reduction of over 10 decibels and a lower temperature rise of 16-20K. The pure circular cross-section of the continuous winding iron core optimizes silicon steel sheet orientation, reducing no-load loss by 20% to 30%.
