Product Introduction
The S11 and S13 series of fully sealed oil-immersed transformers are meticulously engineered to excel in AC 50Hz systems with working voltages up to 20kV. Perfectly tailored for diverse industries such as petroleum, metallurgy, chemicals, textiles, and light industry, as well as high-dust environments, these transformers deliver unparalleled robustness and reliability for all your distribution needs.
Our cutting-edge coil core fully sealed distribution transformer epitomizes the next generation of low-noise, low-loss technology. Featuring a no-joint core, it dramatically reduces no-load loss and no-load current by 60% to 80%. The high and low voltage coils are seamlessly wound on the core pillar for optimal tightness, concentricity, and improved anti-theft properties. Experience an impressive noise reduction exceeding 10 decibels and a temperature rise lowered by 16-20K. The purely circular cross-section of the continuously wound iron core maximizes the silicon steel sheet's orientation, reducing no-load loss by a remarkable 20% to 30%.
