S11, S13 series of fully sealed oil-immersed transformers are suitable for AC 50Hz, working voltage 20kV and below. They are ideal for petroleum, metallurgy, chemical, textile, light industry enterprises, and large dust environments as distribution transformers.
This new generation of low-noise, low-loss transformer features a core without joints, significantly reducing no-load loss and current (by 60%~80%). The high and low voltage coils are continuously wound for tight concentricity and enhanced anti-theft performance. Noise is reduced by over 10 decibels, and temperature rise is lowered by 16-20K.
